In this activity, learners explore how wind energy can be generated on both a large and small scale.

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

In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.

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

Learners will build and experiment with their own windmills made from simple household materials.

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

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

In this design challenge activity, learners invent an emergency shelter that can fit a person and is sturdy and quick to build.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

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

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

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

In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.
