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

In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

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.

This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.

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

In this activity, learners discover how NASA engineers develop experimental aircraft.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

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 activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

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
