Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.

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

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

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

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

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

In this activity, learners determine whether thermal energy can be used for work.

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

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

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 the concept of how brakes can stop or slow mechanical motion.

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

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.
