University of Colorado: Ph Et Interactive Simulations: Electric Field of Dreams

Move point charges around on the playing field and then view the electric field, voltages, equipotential lines, and more. It's colorful, it's dynamic, it's free.

Arrange positive and negative charges in space and view the resulting electric field and electrostatic potential. Plot equipotential lines and discover their relationship to the electric field. Create models of dipoles, capacitors, and...

An interactive simulation with balloons and a sweater that teaches about static electricity, electric charges, and electric force. This simulation can either be downloaded or played online and includes handouts, lesson plans, and...

Investigate static electricity by rubbing a balloon on a sweater and observing what happens. Try it with two balloons. See the positive and negative charges that illustrate why there is attraction or repulsion between the balloons, the...

How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength...

Test the pH of everyday liquids such as coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Investigate how adding more of a liquid or diluting with water affects pH.

An interactive simulation with weights and scales that teaches about balancing chemical equations and conservation of mass. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional...

An interactive simulation will heat, cool and compress atoms and molecules. Watch as they change between solid, liquid and gas phases. Recognize that different substances have different properties which will affect the temperatures for...

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the...

An interactive simulation that teaches about electromagnetic radiation, dipole radiation, and electric fields by observing the effects of changes in sinusoidal, circular, and linear motion on the outward propagation of radiation. This...
