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 engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

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 engineering activity, learners design their own board games.

This activity (on page 2 of the PDF under GEMS Activity) is a full inquiry investigation into technology design and testing.

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

In this engineering activity, learners design and build a mechanical arm to lift a small item.
