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.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

Learners play the role of materials engineers as they test the flexibility of different materials.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.

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

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

Learners develop an understanding of air pressure in two different activities.

In this activity, learners are asked to examine the differences between two materials in a pair.

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 team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.
