In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

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

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

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

Can gelatin (like Jell-O ®) change the speed of light?

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

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

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

In this activity, learners discover how sediment is affected in an oil spill. Learners investigate the differences between heavy and light oil as well as the differences between different sediments.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

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 build a simple qualitative conductivity tester with a battery, bulb and foil.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

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 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.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.
