In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

In this activity, learners determine whether thermal energy can be used for work.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.
