Whirling Windmills
Source Institutions
In this activity, learners are challenged to design and construct a windmill to harness the power of wind.

Roving on the Moon
Add to list DetailsIn this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

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

The Power of Graphene
Source Institutions
This lesson focuses on graphene and its electrical properties and applications.

Keep it Cool
Source Institutions
In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

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

Fizzy Nano Challenge
Source Institutions
This lesson focuses on how materials behave differently as their surface area increases.

Exploring at the Nanoscale
Source Institutions
This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

Lego Mania
Source Institutions
In this activity, learners will put together towers using building bricks, then take the tower apart and challenge themselves to use the same bricks used to build a bridge.

Density Rainbow and the Great Viscosity Race
Learners conduct two activities to investigate two properties of liquids: density and viscosity. In a clear container, learners stack 7 different liquids which will layer according to their density.

Hanging Around
Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

Turning the Air Upside Down: Convection Current Model
Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

Zero-Energy Housing
In this activity, learners investigate passive solar building design with a focus solely on heating.

Turning the Air Upside Down: Warm Air is Less Dense than Cool Air
Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

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

I Can't Take the Pressure!
Learners develop an understanding of air pressure in two different activities.

Turning the Air Upside Down: Spinning Snakes
Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.

Paper Bridge
Source Institutions
In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.

Design a Submarine
Source Institutions
Learners act as engineers and design mini submarines that move in the water like real submarines.
