This is a simple activity fully driven by imagination. Using materials from the home, toys, or items from nature, learners create their own world to play with.

In this multi-part activity learners examine non-point water pollution.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

In this activity, learners work in small groups to match various marine animals with their different environments.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity (located on page 9 of the PDF), learners are introduced to Aesop's fable, "The Crow and the Pitcher." In the story, a clever crow drops pebbles into a pitcher to cause the water level

In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.

In this game, learners take turns guessing toy animals from around their house based on the toy's characteristics.

In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

In this weather activity/demonstration, learners watch as a ping pong ball is suspended in a stream of air supplied by a hair dryer.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.
