In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

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 work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of water).

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

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

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

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 astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

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.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this activity, learners explore how watermills have helped harness energy from water through the ages.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this activity, learners explore the different heating properties of soil and water.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners use raisins and seltzer water to understand why waves don’t move objects forward. Learners conduct two simple experiments to understand the circular movement of waves.

In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

In this quick activity, learners observe how wind creates ocean currents.
