In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

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

In this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

In this activity, learners will use a variety of household and/or natural objects to design a sculpture that balances from a single point.

Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.

In this activity (page 1 of PDF under SciGirls Activity: Forecasting), learners will construct an air cannon by cutting a hole in the bottom of a bucket and stretching a garbage bag over the other end

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

With little more than a plastic bottle, some vinyl tubing, and a length of PVC pipe, make a rocket and a rocket launcher and investigate how rockets fly.

In this Bob the Builder(TM)-themed activity, learners explore what it means to work together as a team.

Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

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

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

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