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 activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

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 will put together towers using building bricks, then take the tower apart and challenge themselves to use the same bricks used to build a bridge.

In this activity, learners explore rocketry and the principals of space flight.

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

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

In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

In this engineering activity, young learners investigate multi-level buildings.

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.

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

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.

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!

In this activity, learners explore different ways to stack cups to meet a personal goal.

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 engineers have improved roofing designs and materials in order to protect the contents of buildings.
