Students design and create their own air-powered rockets, in this hands-on activity.

In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.

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 (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 activity, learners will build a roller coaster for a marble to run on using everyday household materials such as paper towel or toilet paper rolls, cups, boxes, books, buckets, chairs, etc.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

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

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.
