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

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. Learners can test their kite...

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. The activity can be done outdoors on a windy day or...

In this multi-part activity learners examine non-point water pollution. Learners discover ways they may be contributing to this type of pollution and brainstorm ways to change their behavior to be...

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line. This is a...

This activity offers learners and their families several ways to raise their awareness together about home water. Included are a Home Water Audit Chart to help families record their water; a link...

In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community. Learners research such topics as available wind source, cost, noise,...

As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up. Also explored are the natural and human-made options for cleaning up our water...
