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 use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

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 on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

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 activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.
