http://www.compadre.org/psrc/items/detail.cfm?ID=13317
The EJS Phases of Moon JS model displays the appearance of the Moon and how it changes depending on the position of the Moon relative to Earth and Sun. The right window shows Earth (at the center) and Moon, as well as a circle tracing out Moon's orbit. The Sun is far to the right in this picture and therefore the right side of Earth and Moon are bright while the left sides are dark. By using the options, the Moon View window (left) shows the appearance of the Moon as seen from Earth when the Moon is in the position shown in the main window.
The EJS Phases of the Moon JS model includes supplemental documents (see below) that include a middle school lesson plan.Astronomy/Fundamentals/Lunar Phaseshttp://www.compadre.org/psrc/bulletinboard/Thread.cfm?ID=13317Sun, 27 Jul 2014 16:46:21 ESThttp://www.compadre.org/psrc/items/detail.cfm?ID=13317Werner Heisenberg

http://www.compadre.org/psrc/items/detail.cfm?ID=13324
This interactive video tutorial allows students to explore concepts of momentum conservation and energy conservation. This vignette shows that when a suspended block of wood is shot from below with a .22 rifle bullet, the bullet embeds in the block which then rises straight up to a distance of just under a meter. Then, if the block is shot off-center and given a noticeable amount of rotational energy, it still rises to the same height as in the previous example. Careful analysis shows that the block behaves according to the laws of physics.

http://www.compadre.org/psrc/items/detail.cfm?ID=13323
This interactive video tutorial allows students to explore collisions and the implications of Newton's Third Law. This vignette features “person-on-the-street” interviews about forces in collisions as a function of the relative speeds and masses of cars. The viewers are shown various video segments of colliding carts, and real cars, with same and different masses and asked about forces. Over 90 percent of the participants believe that faster objects with more mass exert more force. The dynamics cart collisions with force sensor graphs show that the forces are equal in magnitude, even though the Lego passenger on the less massive cart suffers more injury.

http://www.compadre.org/psrc/items/detail.cfm?ID=13322
This interactive video tutorial allows students to explore projectile motion. After making predictions about the horizontal and vertical motions of a ball, the student performs a video analysis of horizontal and then vertical motions to discover that in Projectile Motion an object undergoes two independent motions -
<br>Horizontal Motion: Constant velocity
<br>Vertical Motion: Constant downward acceleration

http://www.compadre.org/psrc/items/detail.cfm?ID=13294
This small group activity is designed to help upper-division undergraduate students practice using the symmetry arguments necessary for Ampere's Law. Students are asked to find the magnetic field using Ampere's Law for radially-varying steady current distributions inside a cylindrical shell and to make explicit symmetry arguments using Proof by Contradiction as part of their solution. The compare and contrast wrap-up discussion focuses on the fact that all examples have zero field inside the shell; smooth and continuous, but different answers within the shell; and look like an infinitesimally thin wire outside the shell.

http://www.compadre.org/psrc/items/detail.cfm?ID=13302
This small group activity is designed to help upper-division undergraduate students practice using the symmetry arguments necessary for Gauss's Law. Students are asked to find the electric field using Gauss's Law for either a spherically or cylindrically symmetric charged shell of finite thickness and must make explicit symmetry arguments using Proof by Contradiction as part of their solution. The compare and contrast wrap-up discussion on symmetry focuses on the fact that all examples have zero field inside the shell, different answers within the shell, and answers that depend only on the total charge on the shell for points outside the shell.

http://www.compadre.org/psrc/items/detail.cfm?ID=13271
The EjsS Wave Illustration Package contains JavaScript adaptations of Physlet Illustrations from Physlet Physics Chapter 17. Students need to interact with the Physlet, but the answers to the wave questions posed in the Illustration are given or are easily determined from interacting with it. Some Illustrations provide examples of physics applications while others are designed to introduce a particular wave function concept. Typical uses of Illustrations would include reading assignments prior to class and classroom demonstrations.
The EjsS Wave Illustration Package was developed using the Easy Java/JavaScript Simulations (EjsS) version 5. Although EjsS is a Java program, it can create stand alone JavaScript programs that run in almost any PC or tablet. EjsS can also create ePub documents containing multiple simulations.Oscillations & Waves/Generalhttp://www.compadre.org/psrc/bulletinboard/Thread.cfm?ID=13271Wed, 11 Jun 2014 16:30:59 ESThttp://www.compadre.org/psrc/items/detail.cfm?ID=13271
