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.

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

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

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.

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.

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

Learners build simple catapults and use them to launch cotton balls.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.
