Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

In this activity, learners will investigate the part of soil. Explore how clay, silt, and sand make up the dirt in your background. Activity includes step-by-step instructions and extension ideas.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this activity, learners use simple, everyday materials to experiment with balls and ramps.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this math activity, learners observe and sketch cracking patterns in pavement.

You may have tried to throw a curveball or a slider, or even a screwball, with an ordinary baseball and found it difficult to do.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

This activity (9th activity on the page) about hearing demonstrates to learners the importance of having two ears.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners make a photographic image—without a camera!

This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.

In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.

In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.
