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

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

In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

In this activity, learners explore how musical instruments are engineered.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

In this activity, learners explore how boats are engineered to achieve speed.

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

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

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

In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

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

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

This activity (on page 2 of the PDF SciGirls Activity: Milk Carton Boat) is a full inquiry investigation into boat hull design.
