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

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

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

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

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.

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

Learners make their own paper using old newspaper. Learners can make their paper colorful by adding construction paper.

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 activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.

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 build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners explore rocketry and the principals of space flight.
