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...

If you don't get along with someone, it's said that the two of you are like oil and water. Why is this? Explore the phenomenon and explain the phrase in one resource! Science superstars first observe samples of oil and water together....

How does hydrogen bonding explain ice crystals? An engaging interactive answers just that. Scholars explore how polar molecules interact and observe the changes as temperature fluctuates as well as the hydrogen bond attraction.

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...

Can scientists sort molecules based on their interaction with oil and water? The simulation demonstrates how this is possible. Pupils decide when to insert a molecule and observe how they sort themselves based on polarity.

Develop an understanding of the universe. Learners answer 10 multiple choice questions about several topics in astronomy. Questions contain information about the age of the universe, gravitational attraction, galaxies, planets and comets...

Fly around the Martian surface. Pupils view a presentation on the planet Mars featuring a flyover that shows different views of the surface where rovers have landed and explored on different missions. As individuals watch the images, the...

In this online interactive vocabulary skills activity, students answer 10 fill in the blank questions regarding aerospace industry-related words. Students may submit their answers to be scored.

Observe how molecules with hydrophilic and hydrophobic regions move in a mixture of oil and water, and pay attention to changes in potential energy over time. Move and rotate the molecules to see how they interact with their surrounding...

Adjust amounts of ionic charges in this simulation to see how water molecules react to polar substances in solution.
