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 activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

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

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.

In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.

In this activity, learners explore how mirrors reflect light and change the way we see things.

In this activity, learners construct a device that projects images onto a surface, so they can trace landscapes and other sights.

Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.

In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.

In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.

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

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
