In this activity, learners explore how engineers design tire treads to increase safety and reliability.

In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.

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

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

In this activity, learners explore the devices used over time to measure changes in temperature.

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 design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

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

This lesson focuses on graphene and its electrical properties and applications.

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 have met the challenge of keeping foods, liquids, and other items cool.

In this activity, learners will explore how and why weight distribution works.

In this activity, learners will engineer a new shape and use it to create a new pattern with no wasted space.

This lesson focuses on how materials behave differently as their surface area increases.

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

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.

In this activity learners will build roller coasters and test them using small balls or marbles.

Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.
