In this activity, learners explore how nanosized structures can create brilliant color.

In this hands-on botany activity, learners sprout vegetables in film canisters.

In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

In this activity, learners determine the necessary conditions for pea seed germination.

In this outdoor activity and/or field trip, learners investigate the behavior of hopping animals.

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

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

In this outdoor mapping activity, learners explore where plants grow and map plant-distribution patterns.

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

This activity generates learner excitement about light through the creation of a room-sized rainbow.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

In this activity, learners create a "mini sky" in a glass of water in a dark room.
