Science, Optics and You Online Activities for Students The following activities are provided to help you investigate light, optics, and color. They were written by educators with input from scientists, researchers, students, and teachers. Students, teachers, and parents are encouraged to work together to begin an exploration of concepts that help us learn about how we see our world. Activity 1: Perspectives: Powers of 10 - Scientists look at things using their eyes, but they also use a wide variety of specialized tools that give them extra capabilities. Activity 2: K-W-L: What I Know, What I Want to Know, What I Learned - The K-W-L chart is a way for you to put in writing some of your ideas about lenses. Activity 3: Using Media to Explore Light and Optics - Much of the information that you get comes from the media--newspapers, magazines, radio, and television. Activity 5: Looking Through Lenses - There are many different types of lenses, each with their own characteristics and behaviors. How Does It Work?

Transformers In the photograph, note that the coil on the left has fewer coils than that at right (the insets show close-ups). The sketch and circuit show a step-up transformer. To make a step-down transformer, one only has to put the source on the right and the load on the left. (Important safety note: for a real transformer, you could only 'plug it in backwards' only after verifying that the voltage rating were appropriate.) The core (shaded) has high magnetic permeability (ie a material that forms a magnetic field much more easily than free space does, due to the orientation of atomic dipoles). Vp = − Np.dφ/dt . VpIp = VsIs, whence Is/Ip = Np/Ns = 1/r. So you don't get something for nothing: if you increase the voltage, you decrease the current by at least the same factor. In some cases, decreasing the current is the aim of the exercise.

ippex online - main The Physics Classroom Circuit Simulator Applet This is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage. To turn a switch on or off, just click on it. The "Circuits" menu contains a lot of sample circuits for you to try. Full Screen version. Directions. Standalone (offline) versions. Index of Circuit Examples. Home | Practical Physics Find out about our education projects and free teaching resources from the links on this page. We also offer opportunities for school and college students to take part in STEM-related research over their summer holidays through our Nuffield Research Placements. Our work in education includes funding research and supporting its translation into policy and practice. Our current focus is in science and mathematics, foundations for learning, and secondary education transitions. In the past, we have worked in other subject areas including D&T, history, and languages, and further information is available on our curriculum projects page.

Physics 121.6 Applets The following is a list of applet collections that you may find useful. In the table above however I have links to a few of the many applets available on the web that I think are most useful in illustrating the concepts of this course. Applets 1 - Graphs of Position and Velocity This Applet shows a cow on roller skates! Note the shape of the position vs. time graph and the velocity verses time graph for each of the following cases. Try different non-zero initial velocities with zero acceleration. This second applet displays much the same thing. Run Applet... Applets 2 - Vector Addition This Shockwave applet shows the addition of two vectors (Red vector + Green vector = Blue vector). Run Applet... Another applet which shows much the same thing in a slightly different way.... Run Applet... Applets 3 - Projectile Motion This Applet shows the path of a cannonball fired into the air over a horizontal ground. Run Applet... Here is another applet showing projectile motion with no air resistance.

OSP Simulations Overview » home » Simulations » Overview Overview Search for OSP Simulations or browse by topic Applications There are three ways to distribute and run Java programs. Java Applications Java Web Start Java Applets Each distribution method is slightly different and has its advantages and disadvantages. Other websites or curriculum developers may adopt a different distribution mechanism and additional pages in this section show how Open Source Physics programs can be distributed as applets and using Web Start. A classical-physics model of helium consisting of two electrons in a 1/r potential well and interacting through a 1/r potential. Example: Download the classical helium simulation and run the mech_helium.jar file. Jar Files Ready to run OSP models are packaged in a Java archive (jar) file such as osp_demo.jar of osp_guide.jar. Users may also execute a jar file from within a console (terminal) although it is unlikely that students will want to deal with the complexities of command-line syntax.

Free online Absorb resources You can now access hundreds of free whiteboard resources taken from our Absorb courseware, Search Resources Why are they free? We're doing this to help get Absorb known. If you use the resources on our website, they're completely free! Can I use them in my own lessons? Yes! in Powerpoint presentations, with whiteboard software such as Promethean ActivStudio or SMART Notebook, on your school intranet, on your Moodle site or other VLE. Articles on "Electricity" Why three prongs?Why do wall outlets have three holes? "Grounding" and safety. Right Angle CircuitryDo Lenz' Law and the Right Hand rule still work... after you've been turned INSIDE OUT by that greasy black Fog? "Static Electric" misconceptionsA list of things which gave me a warped view of Electrostatics. Speed of "Electricity"? Triboelectric Series If a cat gets trapped in a clothes dryer full of nylon pantyhose, which way do the electrons flow? Where does EM energy flow in a circuit? How Scientists Define the word "Electricity" Quotes from J.C. Barriers to Understanding ElectricityTwenty misconceptions which prevented me from understanding simple electrical science as a student. "Static" Electricity is really just high voltage.Scuff on the rug, then measure your body voltage. Electricity mistakes and 'nitpicking' also How SHOULD we teach Electricity? "Static" sparks Doorknob sparks and zapping yourself on the car door... and people who suffer from an "electric shock" disease.
