This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

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

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!

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

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

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

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

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

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 consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

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

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.

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

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 the engineering behind life vests or personal flotation devices and the challenges met by these devices.

In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.
