In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

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 design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.

In this activity, learners are challenged to design and build a miniature tree house in a potted plant. This activity uses engineering concepts to encourage creativity.

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

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.
