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

Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?

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

In this physics crime lab or demonstration, learners pretend they are criminologists and must find the "muzzle velocity" (speed of the bullet as it leaves the gun) of a gun used to commit a crime.

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 environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

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 use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

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.

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 (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.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.
