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

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

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.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

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

In this activity, learners work in pairs to conduct a series of experiments using a balloon, drinking straw, and paper.

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 activity about electricity, learners build and test a paper clip switch to turn on a light bulb.

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 activity about electricity, learners identify parallel and series circuits. First, learners examine and label diagrams of complete circuits.

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.

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

As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up.

In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

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

In this activity about electricity, learners identify closed and open circuits. First, learners examine and label diagrams of open and closed circuits.

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.
