On Tuesday we did a friction investigation. We watched a video about friction and about air resistance. So they sent me down the hill on a dolly trolley and we made parts to slow me down or speed me up. We took turns to put a part on me but when I was going down the hill I fell off backwards. Miss Dale had a plastic bag and put it on the helmet but I did not come flying off the dolly trolley that time. It was fun learning this – Kye and his partner Hamish managed to speed me up the most!!
