Get excited about this 4.6-billion-year old galaxy – with this STEAM activity – Big Solar System Kit! Fun and practical this DIY project is designed to stimulate discussion and invoke memories about our planetary cousins – their orbit, their colour and size, their distance from the sun and proximity to each other.

Overview: There are 8 planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune… sorry Pluto not you) in our solar system and over 3000 comets! The sun is the largest star and comprises ~99% of our solar systems mass. Jupiter is the second largest object. Did you know that all the planets are on the same plane?

Decorating and constructing the Big Solar System Kit: Each kit includes white polystyrene balls in assorted sizes which are numbered for easy reference. Just match the ball with the number (see instructions) and decorate. Research the planets together so individual colours, patterns and markings can be explored.

When decorating the polystyrene balls, we recommend Paint Sticks or they can be collaged with torn tissue paper, or even covered in Magiclay.
