In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.

In this activity, learners will explore how and why weight distribution works.

In this activity learners will build roller coasters and test them using small balls or marbles.

Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.

In this activity, learners will build a stomp-powered launcher to blast off paper rockets they design. Materials can be found at a local hardware store or you may already have them at home.

In this activity, learners design and build their own parachute using household materials with the goal of landing their passenger safely on a target.

This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.
