Astronomy STEM Activities for Kids (7 results)

Astronomy is science that will challenge your imagination. How many stars in a galaxy? How many galaxies in the known universe? How many strange worlds are out there on other planets, orbiting other stars, and what are they like? Is there life on planets besides Earth? The distances are mind-boggling; the numbers are immense.

How long of a tape measure would you need to measure the circumference of the Earth? Would you need to walk the whole way around the Earth to measure it? Do you think you can do it with just a meter stick in one location? Try this project to find out!   Important: this project will only work within about 2 weeks of the spring or fall equinox (usually about March 20th and September 23rd). Read more

Did you know that the Voyager 2 spacecraft took 12 years to travel from Earth to Neptune, the furthest planet in the solar system? This sounds like a really long time! Maybe not that long if you consider what distance the spacecraft had to travel to get from Earth to Neptune. In this activity, you will make a model of the planets in the solar system and specifically model their distances to scale. Will it explain why the Voyager 2 took so long? Try it and see! Read more

Did you know that there are more planets than stars in our galaxy? All of these planets circle around a star, but only eight of them—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune—circle around the Sun—the star in our solar system. This activity explores the relative size of these eight planets. Will one be much bigger than the other, or are they all about the same size? Read more
