Today in science, Year 5 used some fruits, balls and a tiny black peppercorn to understand the relative sizes of the planets in our solar system. Can you work out which of the objects in the picture represent which planets? We were also surprised to learn that if the volleyball represents the largest planet, then the Sun would barely fit inside our classroom!
Once we had learnt about the sizes of the planets, we created a distance scale on the playground using our measuring skills, where the distance from the Sun to the Earth was 1 metre. At this scale, the furthest planet from the sun (Neptune) was 30 metres away! We noticed during our investigation that the 4 closest planets to the Sun were small, rocky planets. The gassy planets were the 4 that were larger and further away.
