Y4 science day

Over two days year 4 learnt all about different types of friction.

First of all they learnt about surface friction. They carried out an experiment by releasing toy cars from ramps and measuring how far they travelled over differences surfaces. The surfaces they tested were paper, thick cloth, sacking, thin cloth and the table surface. Can you guess which the car travelled furthest on?

 

Next year four learnt all about air resistance. They went outside with their umbrellas so that they could feel the resistance of the air when they ran. They discovered that there was more air resistance when the umbrellas was bigger. They put their DT skills to good use by making parachutes and seeing if the biggest or smallest floated to the ground the slowest. Which one do you think did?
