Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

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 will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

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 evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners construct a home-made journal with simple, everyday materials.

Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

In this activity, learners use simple, everyday materials to experiment with balls and ramps.

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

In this activity, learners construct a simple air pressure launcher for paper rockets.

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

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.

This is a tape and glue activity in which learners make binoculars that they can decorate and then use to go bird watching.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

In this activity, learners observe fly behavior and then build a flytrap.

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

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity, learners make a parachute out of tissue paper, tape, and string. Then, learners test their parachute to see how many paper clips it can carry.

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.
