Magnification vs. Resolution: Can you see the flag on the Moon?
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.
The Great Balloon Race
Source Institutions
In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.
Acorns
Source Institutions
In this outdoor game, learners play the roles of gray or red squirrels gathering and storing a supply of food in "fall" and recovering enough of them to survive the "winter." Learners carry bags repre
Sky Diver
Source Institutions
Students design and build their own parachutes in this hands-on engineering project.
Modeling the Night Sky
Source Institutions
In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.
Pollution in Our Watershed
Source Institutions
By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from
Sound Representation: Modems Unplugged
Source Institutions
In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.
Water "Digs" It!
Source Institutions
In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.
Black Holes: No Escape
Source Institutions
This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.
Nano Latch-n-Catch
Source Institutions
In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.
Investigating Ice Worlds
Source Institutions
In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.
Program a Friend
Source Institutions
In this activity (on page 2), one person "programs" the other like a robot to move through a space, trying to get them to avoid obstacles and reach a goal.

Source Institutions
This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.
How Animals Stay Warm
Source Institutions
In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl
Color Vision
Source Institutions
In this online activity, learners make a whole rainbow by mixing red, green, and blue light. They can change the wavelength of a monochromatic beam or they can filter white light.
Plenty on the Plains
Source Institutions
In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent
