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

In this activity, learners make a barometer, an instrument to measure change in air pressure.

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 about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.

In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.

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 sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

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

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

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

In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

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

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

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.
