In this activity, learners conduct tests for proteins, glucose, and starch.

In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

In this activity, learners explore how different deodorants work. Learners treat agar plates with different types of deodorants and compare the bacteria growth on the plates to the control sample.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this chemistry demonstration, learners observe a chemical reaction that produces a colorful effect.

Learners construct a rocket from a balloon propelled along a guide string.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

Learners build simple catapults and use them to launch cotton balls.

In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

In this activity, which requires adult supervision, learners get to explore the awesome power of chemistry.

In this activity, learners will discover why there are holes in bread.

In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

In this classic activity, learners investigate natural selection by becoming birds foraging for food on an island.

In this activity, learners determine whether thermal energy can be used for work.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.
