Learn about conservation of energy with a skater dude! Build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. You can also take the skater to different planets or even space!

HyperDocs are GoogleDocs that provide an interactive experience for students to explore linked resources about a topic.  This HyperDoc, created by Angela Wilson, provides students YouTube videos, interactive simulations, StudyJams, and games all about force, motion, and gravity.  **Please be sure to make a copy of the Doc before using.**

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including gravitational and normal forces).

After experiencing this module, students should understand that friction is a force that opposes motion (SOL 5.3e). This lesson was written with an inclusive fifth grade classroom in mind, but can be adapted for a smaller pull-out group if necessary. This module was developed by Karin Kaerweras part of a Virginia Commonwealth University STEM initiative sponsered by the Virginia Department of Education.

Learn how friction causes a material to heat up and melt. Rub two objects together and they heat up. When one reaches the melting temperature, particles break free as the material melts away. Arabic Language.

A realistic mass and spring laboratory. Hang masses from springs and adjust the spring stiffness and damping. You can even slow time. Transport the lab to different planets. A chart shows the kinetic, potential, and thermal energy for each spring.

This lesson is part of the Virginia K-12 Computer Science Pipeline which is partly funded through a GO Virginia grant in partnership with Chesapeake Public Schools, Loudoun County Public Schools, and the Loudoun Education Foundation. During this lesson, students will create a storyboard and pseudocode which will be used while creating a simulation using Scratch. 

Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, and the amplitude of the swing. It's easy to measure the period using the photogate timer. You can vary friction and the strength of gravity. Use the pendulum to find the value of g on planet X. Notice the anharmonic behavior at large amplitude.

Watch a string vibrate in slow motion. Wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator. Adjust the damping and tension. The end can be fixed, loose, or open.
