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 engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

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 mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

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.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

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

In this activity, learners are invited to imagine the park of their dreams!

Using simple, inexpensive items, learners build and test submarine models.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

In this engineering activity, learners design and build a mechanical arm to lift a small item.

In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.
