Energy Forms and Changes
Is the ice cooling down the water or is the water melting the ice? Here is a simulation that explores thermal energy transfer with iron, brick, and water. It demonstrates the flow of energy and what happens when each material is either...

The Greenhouse Effect
How do greenhouse gases impact temperature? Have your classes use the interactive software to explore different concentrations of greenhouse gases and their effect on climate. Learners can recreate different atmospheric concentrations...
PhET
Wave on a String
The sound waves of thunder are made when lightning very quickly heats the air surrounding it, expanding faster than the speed of sound. Learners explore waves through their own movement of string or set waves to constantly oscillate....

Balancing Chemical Equations
Just like the old saying goes, "What goes in must come out." This simulation allows pupils to balance chemical equations. The introduction gives three examples before scholars switch to game mode, pick their level, and continue to...

A Catalyst and the Rate of Reaction
More than 90 percent of chemical products are made using a catalyst. Lesson demonstrates the way a catalyst changes the rate of reaction without altering the chemical reaction. A catalyst doesn't appear as a reactant or a product, yet it...
