To start off our topic on Earth and Space, the children investigated the relative sizes of the Sun, Earth and Moon. They made scaled versions of the Sun, Earth and Moon and compared them to each other. They were able to see that the Sun was 108 times bigger then the Earth and the Moon was 4 times smaller than the Earth. Here is an example of one of the scaled models:
Following this, the whole class went outside and measure out how a scaled distance of the Sun to the Earth and Moon. We used a trundle wheel to measure out 150 m and it ended up being all the way across the other side of the field.
In this photo, the Earth and Moon are all the way in the distance near the KS1 playground.
