Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.

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

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin

Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

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

Learners work with plastic sheeting, masking tape, and string to design the perfect material for plastic chair webbing, and then construct their webbing.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

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.

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

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 activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

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