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

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

In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.

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

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

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

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.

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

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 use gelatin as a lens to investigate the properties of laser light.

In this "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.
