In March, 4th class participated in Science Blast. We worked very hard in the weeks leading up to the big event. Our question was ‘Can we slow down gravity?’. We investigated this by creating marble runs with different surfaces to either increase or decrease friction. We raced the marbles and found that we could slow down gravity. The bubble wrap surface added the most friction and slowed down gravity the most. We had a great day out looking at the other projects, visiting the stands and watching the exciting shows!
