Today we built on our understanding of scale to make a scale diagram of the planets. I used an online calculator and found out how big the planets should be if the sun is 3m. The children made the planets and I then explained how far away they would be from each other using known landmarks- see below. We went over it again back in school and looked at the places on the map.
Today we also worked with compasses – the children worked in pairs to write a ‘treasure map – set of directions’ for another pair. At all times the children had to be orientated north. This went well except no-one ended up where expected because we hadn’t set a measurement – we just used ‘paces’.
