This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this activity, learners design miniature cars. Learners can create a telephone car, soccer car, merry-go-round car, or any other theme car they can imagine.

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners explore the concept of force and how pulleys are used in everyday life to make work easier.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this activity, learners will observe a deceptively simple process: a burning candle.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners explore how engineers have developed sorting systems which integrate into manufacturing and packaging processes. Learners explore how coins are made.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

In this activity, learners explore how engineers work in a team to solve problems.

In this activity, learners explore how rescue devices are designed to aid professionals during emergency situations.

In this activity, learners explore how engineering has impacted the manufacturing of canoes over time, including the development of new, durable, and lighter materials.

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

In this activity, learners explore an everyday situation, where either of two or more buttons can ring a buzzer.

In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.
