Lung Capacity
Source Institutions
This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

Exploring the Universe: Pack a Space Telescope
Source Institutions
Space telescopes can offer us better, clearer views of the universe (and of our own planet) than Earth-based telescopes can, but getting these large, delicate pieces of equipment into orbit is tricky.

Inkjet Printer
Source Institutions
In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

Exploring Materials: Thin Films
Source Institutions
In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

The Poor Cartographer: Graph Coloring
Source Institutions
In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.
Magnets are Marvelous
Source Institutions
In this activity, young learners investigate magnets. Learners discover that some magnets are stronger than others and that magnets have north and south poles.

Pico Cricket Compass
Source Institutions
Learners can program a compass to draw a circle by itself using a Pico Cricket, some Legos, and lots of tape! Pico Cricket is required.

Color by Numbers: Image Representation
Source Institutions
Computers store drawings, photographs, and other pictures using only numbers. Through this activity, learners decode numbers to create pictures using the same process that computers use.

Paper Tape Motion Timer
Source Institutions
In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).

Cookie Surface Area
Source Institutions
This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

Breaking Beams
Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

West Coast Shipwrecks
Source Institutions
In this data activity, learners will explore shipwrecks from four National Marine Sanctuaries on the West Coast of the United States.

Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

As the Rotor Turns: Wind Power and You
Source Institutions
In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from

Mini Zoetrope
Source Institutions
In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.

Designing a Wall
Source Institutions
In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

Submersibles and Marshmallows
Source Institutions
In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

Is Anybody Out There?
Source Institutions
Learners listen to and try to decipher a radio message that was sent from Earth to possible intelligent civilizations.

Exploring the Solar System: Mars Rovers
Source Institutions
In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng

Bird Feeder Challenge
Source Institutions
In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.
