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

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

Learners take on the role of environmental engineers as they design water filters.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

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

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.

In this engineering activity, learners design and build a mechanical arm to lift a small item.

Learners participate in a variety of activities modeling different disabilities.

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 ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

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

In this activity, learners are invited to imagine the park of their dreams!

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

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.
