Why is there so much frozen water at Earth's poles? Because water is a polar molecule! Young scientists observe polar molecules moving in a mixture of oil and water. They see the changes in potential energy in the hydrophilic and...

What happens to substances when they dissolve in water? Young scientists investigate the dissolving process with a colorful interactive. The resource illustrates changes in potential energy as solute particles interact with water...

We can see the result of electricity  but not the process itself. The simulation compares electric circuits to a water tower and water wheel cycle. Young scientists adjust the height of the tower, the amount of resistance, and if...

Micelles consist of an aggregate of molecules in a colloidal solution. The simulation presents two different ways the molecules assemble into micelles based on the polarity of the solution in which they are placed. Scholars can set the...

Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...

A colorful and comprehensive PowerPoint highlights this lesson on waves. Junior geophysicists pretend that they are hired to analyze seismic waves. A worksheet is provided to go along with an online article about how compact discs work...

Use the accompanying presentation and colorful technology sheets to introduce your class to the 10 different energy technologies. Connect kids to an interactive computer tool that allows them to combine different types of power...

Learners evaluate the hazards of naturally occurring events. After watching a video concerning safety hazards, students work in groups to discuss the safety issues involved in taking a trip to a mountainous region. Recommendations are...
