Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.
