In this activity, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.

In this activity, learners investigate passive solar building design with a focus solely on heating.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

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

In this activity, learners will discover how to find the "sweet spots" on a baseball bat. Whenever an object is struck, it vibrates in response.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity, learners will build an air cannon out of simple materials you can find around the house. Although air is invisible to the eye, it is not by any means empty space!

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

In this activity, learners build their own construction cranes using tongue depressors and pushpins.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

In this physics activity (page 3 of the PDF), learners will move a load using a lever of each of the 3 classes. They will explore the differences between these classes and which are more effective.

In this activity, learners build a special rolling can that returns back to you when you push it forward. Use this activity to demonstrate the transfer of energy between kinetic and potential energy.

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

In this activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

"Exploring the Solar System: Hide and Seek Moon" is an engaging way for early childhood learners to experiment with some of the tools scientists use to study objects that are very, very far away, and

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.
