In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.

In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.

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

In this activity, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.

In this activity, learners incorporate a simple switch into a battery/bulb circuit. Learners will use their knowledge of circuits to design and make their own switches using common materials.

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

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

In this activity, learners explore how a flashlight works, showing the electric circuit and switch functions of this everyday household item.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

This activity (on page 2 of the PDF under GEMS Activity) is a full inquiry investigation into technology design and testing.

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.

Build and test a scale model of a rainforest canopy walkway.

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

Learners work in groups to build model cars from paper parts. First, each learner builds cars individually and the group times themselves.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

In this activity, learners build their own sound machines and explore the interplay of motion and sound.

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

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 build a figure that moves and "comes to life" when they pull its string.

In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.
