In this activity, learners build water-propelled engines from soft drink cans.

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

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this activity, learners explore watercraft engineering and sailing.

In this engineering design challenge, learners build an air-powered spinning machine.

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

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

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

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.

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

In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.

In this activity, learners build their own rockets from paper, coffee stirrers, and tape. Learners discover that when anything flies, air pressure is always involved.

Learners investigate how drag affects the falling rate of objects.

Learners conduct four simple experiments to demonstrate the effects of air pressure.

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

Learners develop an understanding of air pressure in two different activities.
