Titre : Robust Triboelectric Charging of Identical Balloons of Different Radii Type de document : Article Auteurs : Francisco Vera, Auteur ; Rodrigo Rivera, Auteur ; Manuel Ortiz, Auteur ; Francisco Antonio Horta-Rangel, Auteur Année de publication : 2022 Article en page(s) : p.246-247 Langues : Anglais (eng) Descripteurs : HE Vinci
Electricite ; Electrostatique ; Expérience scientifiqueRésumé : Electrification by rubbing different materials is a well-known phenomenon with a history that began more than five centuries B.C. ago. However, simple experiments can lead to contradictory or inconsistent results, and the history of this phenomena is plagued with non-intuitive results. For example, triboelectric charging by rubbing identical materials is possible. In this work we want to highlight some historical aspects of triboelectricity that could enrich the discussion of electrostatics in an undergraduate physics course. We will focus on the effect of strain on the triboelectric properties of a sample, which we think is not well known to physics teachers. We will show that it is possible to obtain robust polarities by rubbing identical rubber balloons of different radii and we will also show that this charging method can be very useful in introductory physics courses.

Observation ; Particule élémentaireRésumé : Neutrinos are perhaps the least understood of the known denizens of the subatomic world. They have nearly no mass, interact only via the weak nuclear force and gravity, and, perhaps most surprising, the three known species of neutrinos can transform from one variant into another. This transformation, called neutrino oscillation, has been demonstrated only relatively recently and has led to speculation that there might be another, even more mysterious, neutrino variant, called the sterile neutrino. While the sterile neutrino remains a hypothetical particle, it is an interesting one and searches for it are a key research focus of the worlds neutrino scientist community.

AccélérationMots-clés : accélération centripède Résumé : There is a close connection between simple harmonic motion and uniform circular motion. This connection is widely taught and included in standard textbooks. Here, we exploit this connection to simultaneously derive two results from introductory mechanics: the period of a mass- spring system and the centripetal acceleration formula.Previously published derivations of the centripetal acceleration formula often rely on calculus, either via explicit computation or arguing geometrically about limits. One approach relies entirely on the kinematics of vectors, without invoking limits. Our approach likewise does not use limits, but is rooted in dynamics.

Enseignement ; Étudiants ; Physique ; Sociologie de l'étudiantRésumé : In this paper, we describe the work of a teacher (Sarah) as she attempted to use culturally relevant pedagogy in her physics classroom. Culturally relevant pedagogy (CRP) is an approach to teaching developed by Gloria Ladson-Billings, with the goal of encouraging learning through drawing on students cultural capital as a centerpiece of their instruction. CRP meets the academic and cultural needs of diverse students through recognizing and building upon their cultural backgrounds, experiences, and interests in instruction. We describe how our experience working with Sarah broadened and honed our original understanding of CRP as we documented Sarahs instructional successes, as well as the challenges, she encountered in her physics teaching. Based on our work with Sarah, we provide recommendations to inform other physics teachers as they attempt to employ CRP.

Enseignement ; Logiciel ; PhysiqueRésumé : The importance of introducing computational approaches early and actively in science education is widely acknowledged among educators and scientists. Many great ideas have been put forward and implemented by advocates and organizations such as Partnership for Integration of Computation into Undergraduate Physics (https://www.compadre.org/PICUP) and the Science Education Resource Center at Carleton College (https://serc.carleton.edu/teaching_computation/index.html). According to Phys21: Preparing Physics Students for 21st-Century Careers, a recent report by the Joint Task Force on Undergraduate Physics Programs, physics students benefit from learning how to represent physics concepts in multiple ways: mathematically, experimentally, and computationally. In his best-selling book on career advice, Cal Newport argues that quickly and effectively learning how to wield difficult tools is a valuable skill for success.

Élasticité ; Oscillation ; VidéoRésumé : A wood cantilever of length ∼2.5 m is driven into resonance using the hand as a simple driver. Video recordings of these oscillations are analyzed to determine experimental second harmonic (n = 2) damped resonance frequencies. These frequencies are compared to theoretical ones, obtained from measurements of elastic moduli, damping properties, and physical dimensions of the cantilever. Experimental frequencies agree with theoretical ones to within their respective uncertainties. Experiments described here can be incorporated seamlessly into introductory college physics laboratories, following discussions of simple harmonic oscillators (including damping). These kinds of experiments are useful for developing students skills in designing and troubleshooting experiments, analyzing video recordings, and modeling data using computers. The ease of set up and simple apparatus also make these activities ideal for remote learning such as during the recent COVID-19 pandemic.

Baromètre ; GSM ; Instrument de mesure ; Pression ; ThermodynamiqueRésumé : As smartphones have become a part of our everyday life, their sensors have successfully been used to allow data acquisition with these readily available devices in a variety of different smartphone-based school experiments. Such experiments most commonly take advantage of the accelerometer and gyroscope. A less frequently used sensor in smartphone-based experiments is the pressure sensor or barometer. Pressure sensors in smartphones can improve indoor navigation, for example in multi-story shopping malls. In a popular smartphone experiment, the barometer is used to determine the current altitude in an elevator with the barometric height formula. Along with accelerometer data and by deriving the height data to calculate the velocity, z(t), v(t), and a(t) plots can be generated and shown to students in real time.

Didactique des sciences ; Enseignement des sciences ; MagieRésumé : There is an ongoing challenge with STEM education: making physics, math, and science, in general, interesting, understandable, and retentive for college science and non-science majors, K-12 students, and the public. If not imparting detailed knowledge, at least one would like to introduce important concepts that will be remembered, appreciated, and hopefully would be pursued in more detail by audience members. One solution: as noted by Socrates, Wisdom begins in wonder. Indeed, magic as a form of wonderment dates back to Socrates and even earlier. One of the first magic books, The Discoverie of Witchcraft by Reginald Scot, was published in 1584, predating publication of many science texts. In this paper the author, based on recent research, advocates using special forms of magic to both amaze and teach, and in particular to illustrate the wonders of modern physics, i.e., Natures magic, but with connections also to classical physics.

Ephéméride ; Lumière du soleil ; PropriétéRésumé : The camera obscura is a well-known optical device in the form of a closed box with a hole in one of its walls through which light rays pass, forming an inverted image of the external objects on the opposite wall, as can be seen in Fig. 1(a). Despite the simplicity of its basic design, they have been widely used by scientists and artists. In particular, dark cameras have been used throughout history to measure Earth-Sun distance. To do this, ancient scientists used cameras of enormous dimensions to accurately measure the variations in the apparent diameter of the Sun that depend on the Earth-Sun distance. This is because the farther the light travels inside the camera, the larger the projected image will be [Fig. 1(b)]. In this work, the construction of a compact dark camera for educational purposes is presented so that, having reduced dimensions, it allows the images to be very large.

Circuit électronique ; Electronique ; Programmation ; Vitesse du sonRésumé : The determination of the speed of sound in air is a classical experiment, usually performed with a resonance tube apparatus. The measured value can be checked against Eq. (1), which describes the temperature dependence of the speed of sound in dry air. A modern implementation of this speed of sound investigation uses an Arduino Uno microcontroller board, an HC-SR04 ultrasonic distance sensor, and a DS18B20 temperature sensor. The distance sensors transmitter produces a burst of eight ultrasonic rectangular pulses that travel through the air, reflect on an object placed in front at a distance d, and then return to the sensors receiver after an echo time t. This Arduino investigation, unfortunately, is harder to perform than one might expect after a first reading of Ref. 1 or 2. In this article we discuss some sources of experimental errors that can complicate this laboratory activity, and we describe some important steps that must be included in the data collection and analysis procedure, in order to obtain successful results every time.

Cinématique ; Dynamique ; Enseignement des sciences ; ProgrammationRésumé : Ever increasing technological progress opens novel opportunities concerning educational activities, and the ability to use the technology effectively is one of the 21st centurys most demanding skills. The Partnership Forum for 21st-Century Skills (P21) states that no organization can achieve satisfying results without using technology and therefore the use of technology particularly in schools should be at the highest level. Some novel teaching methods have recently emerged based on technological developments, such as STEM education, which is based on the integration of science, technology, engineering, and mathematics. In this study, the motion of a body connected to a pulley system is analyzed by using an Arduino microprocessor and also related mathematical equations. Arduino is a programming platform on which various electronic elements can be connected. There are various Arduino compatible sensors (sound, light, distance, temperature, etc.) that can be coded for their intended use. Due to its cost effectiveness, this technological instrument can be used as a measurement tool in many physics experiments. In this work, the time-varying data of the position of the moving object is determined using the HC-SR04 ultrasonic distance sensor (see Fig. 1). The HC-SR04 distance sensor can determine the distance of the obstacle from the sensor when the transmitted signal is reflected from an obstacle and returned to the sensor, and the Arduino IDE computer program is used to load the corresponding codes into the Arduino and to retrieve the incoming data.

Enseignement des sciences ; Étudiants ; Expérience scientifique ; VidéoRésumé : Recognized as one of the most beautiful experiments of all time, the oil drop experiment performed by Robert Millikan and his graduate students (primarily Harvey Fletcher) is a standard in the repertoire of experiments performed by undergraduate physics students. However, as a teaching lab it does not enjoy a good reputation for three reasons: eyestrain, tedium, and poor, unconvincing results. Several have attempted to make this experiment more student-friendly by improving the optics and replacing the stopwatch with a computer, replacing the eye with a video camera, and utilizing video analysis tools. Currently available versions of the oil drop apparatus for high school and college students have incorporated a number of these features. On the other hand, others are ready to replace the experiment with interactive computer-based simulations. There is another alternative: Have students analyze pre-recorded videos of the Millikan experiment. Besides the Millikan Movies produced at the California State University at Chico, the collection Physics: CINEMA CLASSICS (PCC) contains the essential nuggets from a Physical Science Study Committee (PSSC) educational film made in 1959 sufficient to compute the elementary electric charge.

Apprentissage des sciences ; Efficacité ; Evaluation des apprentissages ; Laboratoires ; Physique ; Résultat scolaire ; Travail de groupeRésumé : Imagine two groups of students in your physics class or lab. In Group A, the students each take on a different task but invest an equal amount of time, energy, and effort in what they do. For example, one student might be the note-taker, while another operates the calculator, computer, or experimental apparatus, and a third keeps everyone on track and makes sure the group is completing assignments correctly. In Group B, on the other hand, the students divide up the work equitably, making sure that each group member participates in every aspect of the various types of work that need to be done. In this case, each student takes a turn operating the apparatus, records their own data, and does some of the analysis. Survey results that we analyzed show that students prefer to work in Group A, but that their physics interest and self-efficacy are boosted most by Group B-style work.

Accélération ; Calcul algébrique ; Cinématique ; Course à pied ; Dinosaure ; VitesseRésumé : Most physics courses begin with one-dimensional kinematics, which is usually restricted to the case of constant acceleration. Here we report a unique exercise for an introductory algebra-based physics course involving the running and non-constant acceleration of the theropod dinosaur Dilophosaurus wetherilli and the world-famous Jamaican sprinter Usain Bolt. Given the interest that most students have about dinosaurs (as well as Usain Bolt), students are excited to examine a hypothetical 100-meter race between Dilophosaurus and Usain Bolt. Since these students have not yet taken calculus, and as part of our effort to build computational skills in our students, numerical methods are used via a spreadsheet to calculate displacements and accelerations numerically from velocity data. This work includes a discussion of uncertainties. Disponible en ligne : Non Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=294014

Diversité ; Enseignement des sciences ; Equité ; Inclusion ; PhysiqueRésumé : Increasingly, the physics community is attending to issues of equity, diversity, and inclusion (EDI), both in language and action. We are more publicly recognizing our individual responsibilities as physicists to address social injustice and systemic oppression. To this end, our physics classrooms are key levers for action. While we have made great strides in teaching traditional content and habits of mind useful in physics, if we expand our educational practices to more completely reflect the full range of what it means to be a physicist, we can make our classrooms more inclusive and equitable and support the needed diversification of our field. Ultimately how, and by whom, physics is enacted are part of the discipline itself and ought to be included in our teaching about the professional practices of physicists. We present two complementary approaches for broadening the focus of our classes, share models for enacting these in middle-division physics courses at two distinct institutional types, and provide evidence of positive impacts on students sense of identity and notions of what it means to be a physicist.

Enseignement des sciences ; Mécanique ; Méthode d'enseignement ; Physique ; RechercheRésumé : Research-based assessments (RBAs) measure how well a course achieves discipline-specific outcomes. Educators can use outcomes from RBAs to guide instructional choices and to request resources to implement and sustain instructional transformations. One challenge for using RBAs, however, is a lack of comparative data, particularly given the skew in the research literature toward calculus-based courses at highly selective institutions. In this article, we provide a large-scale dataset and several tools educators in introductory physics courses can use to inform how well their courses foster student conceptual understanding of Newtonian physics. The supplemental materials include this dataset and these tools. Educators and administrators will often target courses with high drop, withdrawal, and failure rates for transformations to student-centered instructional strategies. RBAs and the comparative tools presented herein allow educators to address critiques that the course transformations made the courses easier by showing that the transformed course supported physics learning compared to similar courses at other institutions. Educators can also use the tools to track course efficacy over time. Disponible en ligne : Non Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=294018

Evaluation des apprentissages ; Physique ; Résolution de problèmeRésumé : For years there has been an acknowledged interest in having students assess the rationality of their solutions to physics problems. In fact, many textbooks now routinely include end-of-problem assessments as part of the authors detailed solutions to examples. Over the past two decades, I have experimented with various forms of end-of-problem assessment strategies for my students in introductory, college-level physics classes. In this note, I will share my observations and recommendations for how this aspect of students solutions can be productive and valuable for them, while providing insights into the students understanding for the instructor.

Energie renouvelable ; Environnement ; Laboratoires ; Physique ; Réchauffement de la planèteRésumé : Although teaching of environmental physics and energy-related topics has increased in the last several years, only a small portion of that has been for non-science majors. Environmental physical science can be used to teach physics to non-science majors by applying learned physics concepts to current issues of interest such as climate change, population growth, sustainability, and renewable energy. The combination of the subject of the environment and a more student-centered learning environment improves the learning experience of the student. It increases the understanding non-science students have for physics. Teaching a physical science class with emphasis on the environment requires labs that engage the students. This lab, in particular, is intended as a final lab in the semester, which shows the students that all the environmental topics are intertwined and influence each other. It ties population growth, climate change, and resource use to show the effects they have on the economy, pollution, ecological footprint, and the welfare of humanity as a whole.

Electronique ; Expérience scientifique ; Instrument de mesure ; ModélisationRésumé : In this article, we present an intriguing experimental exercise that does not fall foul of improper use of instrumentation. The activity is designed as an electronics exercise where the role of the instruments in the measurement of the RC time constant is considered. Essentially, we study the accuracy and precision of a measurement of the RC time constant in a series circuit with an oscilloscope as a function of the value of the resistor, against the predicted linear model of τ = RC. As the value of the resistor approaches the value of the impedance of the oscilloscope, the time constant deviates from the linear model. We show how to adapt the model to account for this and create a mathematical model that agrees with the measurements. It is hoped that such an exercise will solidify a rule of effective use of oscilloscopesthat the resistance of the circuit should be much lower than the impedance of the scopein the mind of the student.

Champs magnétiques ; Planète TerreRésumé : The magnetic field of Earth, Be, is an intriguing topic in the introductory physics curriculum that engages students curiosity and inspires numerous speculations about the nature of this phenomenon. There are several methods for measuring Earths magnetic field. Probably, the most widespread and visual method of measuring the field in student lab experiments utilizes a tangent galvanometer. Recently, PASCO scientific suggested to use a magnetic field sensor for this goal, in a procedure where a magnetic field sensor combined with a rotary motion sensor is rotated in a 2-D plane containing the magnetic field vector of Earth. In this case, the magnetic field detected by the magnetic field sensor is a component of the magnetic field vector oriented relative to the direction of the magnetic field sensor probe (radial component of magnetic field). This means that the detected magnetic field considered as a function of the angle of rotation of the sensor will be a sinusoidal function. The amplitude of this function is the magnitude of Earths magnetic field. In conducting this experiment, initially the sensor is set to zero by placing it in a Zero Gauss Chamber (mu-metal). The equipment setup of the experiment is depicted in the figure shown in Ref. 9. The described experiment requires the use of a dip needle that is a compass pivoted to move in the plane containing the magnetic field vector of Earth. The dip needle shows the dip angle θ (inclination) that Earths magnetic field makes with the horizontal. Besides the previously mentioned devices, this experiment requires the use of an aluminum table clamp, adjustable angle clamp, and angle indicator to ensure proper alignment of the rotary motion sensor in a 2D plane containing the magnetic field vector.

Fréquence de résonance ; Instrument de musique ; MécaniqueRésumé : The interference pattern between two harmonic oscillations with slightly different frequencies are called beats. The beats, as a combined motion, have two different periods, one approximately equal to the period of the original oscillations, and another that is significantly longer and is related to the variable amplitude of the motion. The main objective of this presented work is to engage students attention and demonstrate in a simple way the concept of mechanical beats as a resultant motion of combined oscillations, but also to experience it through a visual projection. The proposed experimental setup is constructed in a way that satisfies both objectives and it consists of two parts that allow us to demonstrate in real time the combination of two harmonic motions. In the first part, the resultant motion is generated by the oscillations of two parallel rulers equipped with mirrors, and in the second part the visual demonstration of the beat occurs on a phosphorescent rotating foil by using a blue violet laser beam.

Aristote ; Histoire des sciences ; Mécanique ; Mouvement ; Paradoxe ; RoueRésumé : Aristotles wheel paradox is a fascinating example of a classical puzzle that can pique a students interest. The existing explanations in the literature are limited to discussions of the wheel trajectory; in this paper, we study the paradox from the viewpoint of motion decomposition, an approach we consider more intuitive. The motion of the point at the wheel edge can be resolved into a uniform rectilinear motion and a uniform circular motion. By analyzing the velocity of the point on the edge of the small wheel, we conclude that when the large wheel is rolling at a constant speed without slipping, the small wheel does actually both roll and slide.

Aimants ; Champs magnétiques ; Induction électromagnétique ; Loi de Faraday ; Physique ; Théorie des cordesRésumé : The question of how the processes around the Faraday generator with its rotating magnet should be interpreted has been controversial since its discovery by Faraday. Does the magnetic field rotate together with the rotating magnet or does it remain stationary? Furthermore, does one only need Faradays flux law to interpret inductive processes, or are there processes in which this law fails and a satisfactory explanation can only be found with the help of the Lorentz force? This question seemed to have been re-solved recently in favor of Faradays flux law, which has been described as a universal law that applies without exception to every conceivable case. The measurements presented here raise doubts as to the validity of this interpretation. Disponible en ligne : Non Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=294030

Three years later, when I applied to universities, two of my four applications were rejected. I was not qualified to apply, because I had not completed a physics course. As I sat in college Physics 1 on the first day of class, the professor asked us to raise our hands if we had not studied physics in high school. I raised my hand. Suddenly, panic struck me as I realized that not one of the other 400+ mostly male students had raised a hand. In that class I learned that physics teaching means direct lecture, notetaking, and occasional entertaining demonstrations. Not a good fit for a social woman from a very poor family in the East Los Angeles area. Working half time precluded joining study groups, so my struggle to learn physics was difficult and lonely. I succeeded primarily by sheer stubbornness and fear of failure. How I wish I had had fellow travelers on my path.

Démonstration ; Dynamique des fluides ; Loi binomiale ; Newton, Isaac ; Physique ; Pression ; Probabilité ; VitesseRésumé : While Bernoullis equation is one of the most frequently mentioned topics in physics literature and other means of dissemination, it is also one of the least understood. Oddly enough, in the wonderful book Turning the World Inside Out, Robert Ehrlich proposes a demonstration that consists of blowing a quarter coin into a cup, incorrectly explained using Bernoullis equation. In the present work, we have adapted the demonstration to show situations in which the coin jumps into the cup and others in which it does not, proving that the explanation presented in Ehrlichs book based on Bernoullis equation is flawed. Our demonstration is useful to tackle the common misconception, stemming from the incorrect use of this equation, that higher velocity invariably means lower pressure.

Apprentissage des sciences ; Discussion ; Evaluation ; Métacognition ; Physique ; RéflexionRésumé : Learning in the classroom is highly influenced by the experiences a teacher plans for students. Concerned that students were not achieving adequate conceptual knowledge during traditional undergraduate physics courses, the authors used the Making Sense of SCIENCE curriculum to tailor a course for 21 pre-service elementary teachers at the University of Mississippi. The organization of instruction, facilitation practices, discussion opportunities, and assessment of content are all important aspects of the learning process. We found the changes we implemented significantly impacted the learning of students enrolled in this course.

Energie cinétique ; Loi physique ; Mécanique ; Mouvement ; VitesseRésumé : The law of conservation of momentum is a fundamental law of nature. It states that the momentum of an isolated system is conserved. In high school or introductory-level physics courses, for simplicity, teachers and textbooks always use collisions in one dimension as the examples to introduce the concept of conservation of momentum. To solve simple problems involving one-dimensional collisions, all we need are basic algebraic manipulations. However, the relation between physical quantities, such as mass and the changes in velocity and kinetic energy, of the colliding objects is not obvious. For instance, if an object A collides with a stationary object B, what is the direction of A after the collision? Is it possible that the final velocity of A is zero in an inelastic collision? In this paper, we argue that the so-called velocity space approach can be highly effective for physics teachers in building a better understanding of the law of conservation of momentum.

Champs magnétiques ; Eclipse (astronomie) ; Rayonnement cosmique ; Soleil (astronomie)Résumé : During the August 21, 2017, solar eclipse, high school students measured secondary cosmic ray flux using QuarkNet detectors. These students conducted experiments examining cosmic ray flux, shower, speed of muons, and muon lifetime using QuarkNet cosmic ray muon detectors (CRMDs). These detectors measure muon flux of momenta greater than ~2 GeV, a threshold imposed by deflection due to Earths magnetic field. This study utilized CRMDs, which are readily available for students, to investigate any deviation in secondary cosmic ray flux resulting from a solar eclipse. Other groups have conducted experiments regarding cosmic rays during eclipses: Kandemir et al. reported on low-energy muons (under 1 GeV) during the eclipse of August 11, 1999; Nayak et al. and Bhaskar et al. studied air showers for gamma ray point sources; and Nishina et al. studied muon flux during a 1936 eclipse. Cosmic rays are charged particles created in exploding stars and active galaxies and travel through interplanetary space at relativistic velocities. The flux is largely unchanged between day and night, when Earth blocks the Sun, and the presence of the Sun and Moon has little effect. A total eclipse provides a dramatic opportunity to search for that fraction of cosmic rays created by the Sun that are intercepted by the Moon. We hypothesized that muon flux will change during a total solar eclipse; however, we designed the experiment to search for signals at various angular scales near the direction of the Sun and to set upper limits on production from the Sun if no signal was observed.

Acoustique ; Enseignement des sciences ; Mécanique ; Optique et photonique ; Physique ; Smartphone ; Vitesse du sonRésumé : In recent years, with the more powerful functions of smartphones, the use of sensors integrated by mobile phones as an auxiliary tool for physical experiment teaching has become more popular. Combined with the related mobile phone apps, people easily can develop and expand the physical experiment contents of mechanics, optics, acoustic phenomena, and so on. These experiments not only help students master the relevant laws of physics, but also permit or encourage students to carry out experimental research, greatly increase students interest in learning, and meet the training requirements of the Next Generation Science Standards. Recently, some experiments about measurement of speed of sound have been introduced. It is amazing and interesting that people can use simple tools to measure the speed of sound. This kind of experiment is very helpful to improve students practical ability in experiment design, data acquisition, and analysis. Inspired by the above experiments, especially the Kundts tube experiment, we demonstrate the acoustic resonance in an air column using a plastic tube, a mobile phone, a loudspeaker, and a tape measure. Through the resonance phenomenon of an air column, the speed of sound in air can be calculated conveniently. The experimental results are in good agreement with the reference value. This kind of homemade experiment can provide guidance for students to carry out relevant research in a non-laboratory environment.

Aimants ; Courant électrique ; Electromagnétisme ; Enseignement des sciences ; Loi de FaradayRésumé : In one of the Faradays experiments an electric current is induced in a conducting loop when a magnet in front of it moves towards or away from the loop. While the direction of circulation of the electric current in the loop has only two options, it depends on three experimental conditions that generate eight cases. Even though the Faraday law or the Lenz law by itself answers for the current sense in each case, we think that a graphic synthesis of all the cases and its corresponding result is a new and interesting exercise we want to discuss. The resulting diagram is a starting point for other exercises on the induced current that a teacher might propose to their students in introductory college physics.

Electronique ; Enseignement des sciences ; Mathématiques ; Modélisation ; PhysiqueRésumé : The subject of mathematics is important for many other subjects, including physics. The questions we ask in physics often need a mathematical translation to be graphically interpreted and transformed. Students learn physics when interacting with physical questions; questions from physics also give insights and discoveries in mathematical problems. In physics we often deal with questions that benefit from being illustrated with mathematical tools. A scientific theory (in physics or in another science) is an isomorphism between physical reality and a mathematical model.

Liquide ; Miroir ; Optique et photonique ; Réfraction ; Soleil (astronomie)Résumé : The refractive index (RI) is probably the single most important parameter in optical systems. Chromatic dispersion, on the other hand, indicates how the RI depends on the wavelength and is central in, e.g., optical communication systems. Chromatic dispersion also plays an important role when teaching optics due to the captivating natural phenomenon of the rainbow and the white light decomposition with a prism. In this work, we propose and explore a method to characterize the refractive index of transparent liquids in the visible range without any dedicated equipment or device (such as prisms, goniometer, laser, detector, etc.).

Astronomie ; Enseignement à distance ; Mécanique ; Mouvement ; PlanèteRésumé : Thanks to the COVID-19 pandemic, virtually all in-person instruction was shut down across the country in 2020 and beyond. This posed special problems for laboratory-based science courses, as those are defined by the conducting of experiments in person and often with specialized equipment unavailable outside of the classroom. Here I discuss a semester-long project for introductory astronomy that can be performed at home with very basic and inexpensive equipment. And, thanks to the vagaries of the orbits of the planets, variations of this activity can be carried out in many future semesters.

Enseignement des sciences ; Littératie ; Physique ; Vocabulaire scientifiqueRésumé : When I began teaching high school physics, I found that many of my students were not just struggling with the mathematics of physics but the way the language was used. Physics is sometimes discussed as being a second language where common words are coded with specific alternate definitions (consider how you use the word delta). Furthermore, many of our students are English Language Learners. Thus, providing developmentally appropriate assistance to building scientific vocabulary not only addresses equity issues but can be a highly effective teaching strategy. In this article, I provide an example of one such approach to addressing literacy issues: a vocabulary building story on Convection, Conduction, and Radiation.

Programme d'études ; Publications ; UniversitésRésumé : Ulysses by James Joyce (18821941) has a surprising amount of 19th-century, classical physics. The physics community is familiar with the name James Joyce mainly through the word quark (onomatopoeic for the sound of a duck or seagull), which Murray Gell-Mann (1929-2019 Physics Nobel Prize 1969) sourced from Joyces Finnegans Wake. Ulysses, however, was ranked number one in 1998 on the Modern Library 100 Best Novels list and is, in whole or in part, in the literature curriculum in university English departments worldwide. The fact that Ulysses contains so much classical physics should not be surprising. Joyces friend Eugene Jolas observed: the range of subjects he [Joyce] enjoyed discussing was a wide one [including] certain sciences, particularly physics, geometry, and mathematics. Knowing physics can enhance everyones understanding of this novel and enrich its entertainment value. Ulysses exemplifies what physics students (science and non-science majors) and physics teachers should realize, namely, physics and literature are not mutually exclusive.

The ship sank in a fraction of the time designers had estimated following a worst case scenario. The purpose of this article is to examine the atmospheric refractive phenomena that might have played a significant role in obscuring the iceberg from Titanics two lookouts. We describe a way in which these phenomena can easily and inexpensively be brought to students in our introductory physics classrooms.

Analyse mathématique ; Apprentissage par problèmes ; Epistémologie des sciences ; MathématiquesRésumé : When students are learning to use math in physics, one of the most important ideas they need to learn is that equations are not just calculational tools; they represent relationships between physical variables that change together (co-vary). How much a change in one variable or parameter is associated with a change in another depends on how they appear in the equationtheir functional dependence. Understanding this sort of relationship is rarely emphasized in introductory mathematics classes, and students who have not yet learned to blend conceptual ideas with mathematical symbols may not see the relevance and power of this idea. We need to explicitly teach functional dependence as part of our effort to help students learn to use math productively in science Disponible en ligne : Non Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=290339

Energie ; VitesseRésumé : What happens when a perfectly elastic ball collides with a completely inelastic ball? It is shown that the outcome depends on the stiffness of each ball. A standard textbook problem in mechanics is to calculate the outcome of a head-on collision between two balls using conservation of momentum and kinetic energy. It is easily shown that the outcome depends on the relative mass of the balls and their initial speeds. In practice, there is always a net loss of kinetic energy during a collision, which can be expressed in terms of the coefficient of restitution (COR) for the collision. The COR is defined as the relative speed of the two balls after the collision divided by the relative speed before the collision. In a perfectly elastic collision the COR is unity. In a completely inelastic collision, the COR is zero. Disponible en ligne : Non Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=290340

Apprentissage des sciences ; Congrès ou conférence ; Enseignement des sciences ; SciencesRésumé : The Next Generation Science Standards (NGSS) is the latest initiative to promote authentic scientific work in the classroom. Previous reform efforts have not caused the change in teacher practice and student learning that was hoped for, despite their ubiquity and accessibility. The culprit may be the culture of school that is often recalcitrant to change. This article argues that the NGSS may be the most scientifically aligned reform but may be doomed to failure unless it can be connected with the culture of schooling. The central idea offered here is to incorporate the professional practice espoused in the NGSS by using a cultural emblem of school sciencethe science fair. The trick is to transform the science fair into a science conference. Disponible en ligne : Non Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=290341

Acoustique ; Mesure acoustique ; OrdinateursRésumé : The typical sound of George Lucas laser blaster in the Star Wars series is well known. What does a laser blaster in Star Wars sound like, and why? Here we show a simple way to produce this sound by using low-cost lab material, like a spring or a Slinky (Fig. 1). Building on the work of Crawford, who analyzed the sound of a Slinky using oscilloscopes, we present a technique for analyzing the sound using mobile devices. For a deeper quantitative analysis, a PC with open-source software is used. Disponible en ligne : Non Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=290342

Astronomie ; Rayonnements électromagnétiquesRésumé : When teaching a general education introductory astronomy course that includes a mathematics prerequisite, it is important to convey that formulas and equations physically represent properties of actual objects and processes that occur that can actually be observed. Students with varying comfort levels with mathematics often need to be convinced that problems involving formulas and equations are more than simply mathematical exercises, but are meant to enhance their understanding of the physical concepts. One way to attempt to do this is to introduce equations related to concepts that are being studied qualitatively, for instance, with lecture-tutorials. Here are several examples making use of lecture-tutorials on topics related to light and stars from the popular manual Lecture-Tutorials for Introductory Astronomy Disponible en ligne : Non Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=290344

Chutes accidentelles ; Cinématique ; Equation ; VitesseRésumé : We investigated a very long chain falling from the pile on the edge of a table to the floor both experimentally and theoretically. In this very simple and novel configuration we showed that the velocity of the chain quickly converges to its asymptotic value, and that the steady-state velocity is proportional to the square root of the height of the table. The results are general and do not depend on the type of chain. We explained our measurements using simple dimensional analysis and Newtons second law. The measurements do not require any special instrumentation other than a stopwatch, a desk, and a chain. This experiment can be performed in any classroom.

In addition, they have the opportunity to follow the QR-coded experimental videos repeatedly, after performing hands-on experiments. Thus, the specialized instructional materials not only help them understand the concepts of transparent, semi-transparent and non-transparent but also develop their social skills.

Applications mobiles ; Didactique des sciences ; Exploration de l'espace ; Mars ; Pression atmosphériqueRésumé : Physics is not a very popular subject at German schools, and several studies indicate that girls are less interested than boys in the traditional physics curriculum. To address this problem, physics education should be up to date, context oriented, interesting for girls and boys, and emerge from their everyday life. The ROSE study shows that astronomy, human biology, and space are interesting for boys and girls and therefore a suitable context for physics lessons. In the field of astronomy and space exploration, the research is both highly current and part of the students life, as they hear about discoveries and missions in the news. One possible future space mission is the human exploration of Mars. Such a trip is not easy; various factors have to be considered and risks must be minimized. One risk is the vacuum in space while there is higher air pressure in the spaceship itself. This aspect must be taken into account when designing a spaceship, for example, the Crew Dragon by Space X.

Lumière ; Optique et photonique ; RéfractionRésumé : The refractive index is a number that governs how light changes its direction of propagation as it enters one material medium from another. This phenomenon is known as refraction and the angles of incidence and refraction of light, referred to the normal to the interface of the two media at the point of incidence, are related by Snells law. The refractive index (RI) depends on the color (or wavelength λ) of light. Tables of values of refractive indices for various media and wavelengths of light, with respect to vacuum, are readily available. The refractive index of a material can be measured by many methods, for example, by using a spectrometer in conjunction with a prism made of the experimental substance. An important class of methods of measuring RI involves the formation of interference patterns. Interferometric measurements are concerned with the study of separation between bright fringes (or dark fringes) resulting from the superposition of light waves, originating from a single source and propagating along paths of different optical lengths (refractive index multiplied by geometric path length). Researchers have exploited (nearly) monochromatic light from laser sources to enhance precision in measuring refractive index by applying interferometric techniques.

Didactique ; Effet doppler ; Espace ; Relativité ; VitesseRésumé : Gravity bends light. One can argue this by reasoning that a beam of light should travel in a curved path when viewed from within an accelerating frame of reference, and then invoking Einsteins principle of equivalence, which asserts that the effects observed in an accelerating frame of reference are indistinguishable from the effects observed in a uniform gravitational field. If light bends in an accelerating reference frame, it must also bend in a gravitational field.

Didactique ; Electricite ; Magnétisme ; MesureRésumé : In physics lessons at secondary school and experimental physics courses at universities, the magnetic field inside a current-carrying solenoid is considered quantitatively. The corresponding equations and theories are supported by measuring the magnetic flux density inside the solenoid with a Hall probe. It has already been shown that smartphones with their internal magnetometer are suitable for quantitative investigations of magnetic fields. E.g., Silva proposed to wind a small coil on a pen and investigate the dependence of the stray field on the number of windings. Ogawara et al. placed a smartphone inside a current loop and studied the dependence of the flux density on current I.

Astronomie ; Bases de données comme sujet ; NASA (USA)Résumé : Many professional astronomy archives are open to the public; software tools are getting better all the time to not just access these data, but also work with them. The Infrared [IR] Science Archive (IRSA) is NASAs home for long-wavelength data, both space- and ground-based. You can use this interface to pull data to create your own lessons, or turn students loose in the archive to discover features of our multi-wavelength universe.

In this article I introduce three lab activities, appropriate for a high school physics course, that are related to temperature and thermodynamics. The first of these is a graphing lab where a dual Fahrenheit-Celsius thermometer is used to create a best-fit trend line that serves to introduce this graphing skill. The second is an experiment to find the melting point of coconut oil, which is a convenient and widely available substance, with a phase change in a safe temperature range. The third is a safer alternative or follow-up to the classic Burn a Peanut lab, where I have students investigate how many calories are in a heat pack hand warmer. The labs are designed to be affordable, easy to set up, and work well as inquiry investigations.Disponible en ligne : Non Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=290533
