In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

In this activity, learners help identify native and non-native plant species, learn about invasive species, and determine how native plants provide a healthier habitat.

Using indirect methods, learners determine the shape and size of a piece of carpet hidden under a piece of plywood.

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

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 will discover why there are holes in bread.

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.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

The goal of this Star Wars activity is to design and build a balancing device to help an Ewok escape the Imperial Forces by sliding down a tightrope to safety.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.
