Make a Comet on a Stick
Comets are large balls of ice, rock and dust but you can think of them as large dirty snowballs that travel through the Solar System. The main part of a comet is called the nucleus. Most of the time comets are too faint and dark for us to see, but as they get closer to the Sun, the ice starts to heat up and some of it turns into gas. The gas and dust released forms an enormous tail that stretches out behind the nucleus.
Why not make a model to explore the different parts of a comet!
