Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?

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 activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

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

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.
