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

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 fun hands-on activity learners explore a simple machine: the lever. What happens to a load when you multiply the length of a lever? Find out here!

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

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

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 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 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, 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.
