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

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

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

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

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

In this activity on page 4 of the PDF (Behind the Scenes with Chemistry), learners make some special effects, including snow and breaking glass, with supplies found in the home.

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.
