In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this activity, learners create a colorful foam fountain by adding yeast to a chemical reaction. This activity introduces chemical reactions to young learners and teaches the concept of catalysts.

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity, learners work in teams to construct and test fly drinking straw rockets. Learners explore how changing the rockets' fins affect flight distance.

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.

In this activity about electricity, learners imagine that they are out in the wilderness and it is getting dark. Their task is to use the materials supplied to build a simple flashlight.

In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.

In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.
