Using a length of till-roll create a scale representation of the Solar System. Great for learning the order of the planets and for showing how they're spaced within the Solar System.

Aimed at pupils aged 11-14 this workshop makes use of some basic algebra and graphs to reinforce ideas about the effects of gravity and how these effects depend upon where in the Universe you are.

The Earth spins once every 24 hours which gives us the length of the day. It also orbits around the Sun once every year, which is about 365 days. However, other planets spin and orbit at different speeds, so their days and years are different lengths.
