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

Learners construct and launch paper helicopters.

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

In this engineering design activity, learners will design, test, and build a “haunting machine” to solve a Sherlockian mystery.

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.

Students design and build their own parachutes in this hands-on engineering project.

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.

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

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 design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.

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.

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