Galaxy Slime

This activity uses slime making as a tool to talk about why we need X-ray and infrared observatories to "see" through the dust in a galaxy. Using simple household ingredients, directions and more information are at

Binary Bracelets & Pins

How do you write in binary code? Find out how binary code works and then embed your own name or nickname on a bracelet using this secret code. Or, try binary pins for a shorter exercise:

Make Your Own Zine

A zine is a small, free, self-published folded print that is usually photocopied and handed out in small batches. Zines can be about any topic and are creative ways to dive into something that interests you, from art to science fiction to social justice to poetry. They are meant to be do-it-yourself, hand-made, and shared with others, great for those who like to cut, fold, paste, decorate, stamp, and more.

Make a Paper Spacecraft

Learn more about some of NASA's eyes in the sky by constructing your own paper models in this publication of "NASA's Great Observatories." The Chandra X-ray Observatory, the Hubble Space Telescope and the now-retired Compton Gamma Ray Observatory are all included in the paper model instructions (suitable for grades 5 and up).

Fold an Origami Star

Learn about the ancient art of paper folding, how it connects to modern science, and then fold your own simple star.

The Science of Flying: Paper Airplanes

While kids might like to make paper airplanes, it’s much more than child’s play. There is a lot of science and engineering that goes into making a successful paper airplane. Experiment with different aspects of flying a paper airplane, and most importantly, have fun!

Brick by Brick: Building an X-ray Spacecraft

NASA's Chandra X-ray Observatory is a telescope specially designed to detect X-ray emission from very hot regions of the Universe such as exploded stars, clusters of galaxies, and matter around black holes. Because X-rays are absorbed by Earth’s atmosphere, Chandra must orbit above it, up to an altitude of 139,000 km (86,500 mi) in space. Learn about Chandra, and assemble your own mini-craft with the suggested instructions at

Light Up the Stars

A hands-on activity using printable templates and creating simple paper circuits. Good for MakerFaires, libraries, classrooms and other STEM related events where participants can create their own take-away.
