In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.

In this activity, learners explore the engineering and principles behind working elevators.

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

This activity (on page 3 of the PDF under GPS: Sailboat Design Activity) is a full inquiry investigation into design optimization.

In this activity, learners will use household items to design and build an elevator that will carry 2 passengers to a height of 16 inches...or higher!

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

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

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 are challenged to design a wind-powered car using only a handful of household materials.

In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.

This activity is a hit for family events and all ages—some will finish in 45 minutes; others can go on for hours.
