In this activity, learners investigate passive solar building design with a focus solely on heating.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

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.

Learners act as engineers and design mini submarines that move in the water like real submarines.

In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.

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

In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex

In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

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 explore different ways to stack cups to meet a personal goal.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

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

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

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 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 activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.
