When chatting about our new topic, the children have been discussing the size of the sun, moon and stars and that they all look so tiny.  We did an experiment outside to show that as things get further away, they appear smaller, which is why the sun, moon and stars look so small.  We used two pieces of card and checked at the beginning of the experiment that they were exactly the same size. Rome then walked further and further away from Oli and we noticed that the piece of card Rome was holding appeared much smaller!
