In this hands-on engineering project, kids use two simple machines, levers and inclined planes, to construct their own pinball machines.

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

In this engineering activity, young learners investigate multi-level buildings.

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

In this engineering activity, challenge learners to make a "grabber" that can pick up trash. Learners use simple materials to create pinchers that can grab small items.

In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

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 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

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 activity, learners design a bungee jump for an egg using nylon stockings.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.

In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

In this project, students explore how levers work, by making a puppet with moving limbs.

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.
