Blink
Source Institutions
In this self-measuring activity, learners observe and record how many times a minute they blink, take a breath, and chew, as well as how many times a minute their heart beats.

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.

Constellation Viewer
Source Institutions
In this activity, learners will explore what a constellation is and make their own.

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.

Counting Your Lucky Stars
Source Institutions
In this activity, learners sample a star field to estimate the number of stars in the universe.

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.

Thrush Songs: An Interactive Game
Source Institutions
In this interactive game, learners listen to the songs of four different thrushes and then try to match each bird with its song.

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

Control a Bird’s Flight
Source Institutions
In this engineering design challenge, learners make a bird and then control its flight with attached strings.

Floating Head Cup
Source Institutions
In this activity, learners watch a figure "magically" float up through the air.
Math and Creativity Posters
Source Institutions
These math posters have questions written on them, such as: How many colors can you name in a minute? or How many seconds can you balance on one foot?

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.

Sticky Structures
Source Institutions
In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

Out of Sight: Remote Vehicle Activity
Source Institutions
In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.

Air Cannon
Source Institutions
In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

Carbon Cycle Poster
Source Institutions
In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

Tube Zither
Source Institutions
In this activity, learners explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.
