In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

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).

From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

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

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

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 explore how engineering has developed various means to remove impurities from water.

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.

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.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
