In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this activity, learners are challenged to design and construct a windmill to harness the power of wind.

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

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.

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 will engineer three different parachutes to test how well each one works.

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 investigate passive solar building design with a focus solely on heating.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

Build and test a scale model of a rainforest canopy walkway.

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

Learners construct an electricity-generating wind turbine out of a plastic bottle.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
