In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

This is a quick, yet dramatic activity/demonstration that introduces learners to the concept of energy transfer. A small ball is placed on top of a large ball and both are dropped together.

In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

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

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
