Students conduct a series of experiments on water electrolysis. In this chemistry lesson, students explain what happens to the molecules during the process. They cite real world applications of electrolysis.

Students discuss radiant energy from the sun, performing a simple experiment with sun glasses and bright light to demonstrate the concept. Students further participate in simple in-class experiments to demonstrate: air density as it...

Students watch a video clip about German submarines lost during World War II. They work together to create their own submarine out of a plastic bottle. They test the buoyancy of the submarine in different activities.
