This afternoon we learned that a force is a push or a pull.

We did a range of experiments and practical activities to show that unsupported objects fall downwards due to gravity.​ We looked at our hair when we do a handstand, watched paint run down a sheet of paper and threw objects in the air to watch them fall. We realised that Gravity is an invisible force that makes unsupported objects fall towards Earth. Throughout history, people have tried to explain this force. Galileo realised that gravity causes objects of the same shape, but different mass to fall at the same speed.​ Although some of us predicted that heavier objects would fall faster, we proved Galileo right by dropping 2 identical water bottles – one full and one half full – at the same time. They both hit the ground at the same time. We also learned about Isaac Newton who realised that Earth must have a force towards its centre that pulls things straight down. He is the person that named it “Gravity”.
