These 10 Space Activities for Kids Are Out of This World

From distant stars, to black holes, to the search for life on other planets, outer space has so much to explore. Inspire your child to think out of the box (and out of this world!) with our favorite space-themed science projects.

Straw Rockets (Ages 3-16)

How fast do you think a rocket needs to go in order to launch into orbit? A shuttle needs to go from zero to 18,000 miles per hour (29,000 kilometers per hour) to get to space! (This is nine times faster than the speed of a rifle bullet!) While these paper straw rockets don’t fly nearly as fast, we had a bunch of fun watching them zoom off. Give it a try and see how well your rockets fly!
