Watch out for that marshmallow!
Last week, we learnt that there are three forces that make an object move: push, pull and twist. Today we took that learning one step further.
We decided to discuss what would happen if you change the amount of force an object receives. For example if you push a ball very hard compared to gently. We decided as a class that the more force you give something the further it will move.
However, we needed to test if we were right. This is where the marshmallows come in. We pushed a marshmallow into one end of a pasta straw (pasta is biodegradable and will not end up polluting our oceans). We used our breath as the push force. We used a gentle breath as a small force and the marshmallow popped out of the pasta straw but didn't move very far. Next, was the big test. With the biggest force our lungs could make we sent the marshmallow hurtling across the room.
In the end we were right. The more force you give an object the further it will move.
