Touch Down
Source Institutions
In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

Reflections
Source Institutions
In this quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.

Static Water
Source Institutions
In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

Can Energy be Created or Destroyed?
Source Institutions
In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

Eyedropper Hydrometer: Buoy your understanding of density
Source Institutions
Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

Physics in the Toy Room: Toppling Towers
Source Institutions
In this physics activity, learners use square blocks to explore how towers fall. Learners attach a piece of string to the side of a block and then construct a tall tower on top of this base block.

Personal Pinhole Theater
Source Institutions
Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!
Glowing Tonic
Source Institutions
In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.
Pour Some: Measure Serving Size
Source Institutions
Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

Chocolate (Sea Floor) Lava
Source Institutions
In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

Tomb Mapping
Source Institutions
In this activity, learners examine the culture and history of the tomb site.

Pollution Patrol
Source Institutions
In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

Heart of the Matter
Source Institutions
In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

The Carbon Cycle Game
Source Institutions
In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

What is a “Convection Cell”?
Source Institutions
In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

Smooth Operator
Source Institutions
In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

Balloon Inside a Bottle
Source Institutions
In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.

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

Floating Head Cup
Source Institutions
In this activity, learners watch a figure "magically" float up through the air.

How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
