Science experiment

In primary we did a science experiment about friction. We went to Memorial Park were there was a slide. We took sacks and went down the slide we also tried going down in our normal clothes. We had
lots of fun that day and we found out that the sack was faster. We also did other friction tests. We had to bike through bark and sand to see who got the furtherest. In room 29 we had a roller coaster competition, were you had to make a small roller coaster. Our roller coaster was really well decorated but it didn't always work. We had to show it at Rimu House Hui, it came second to the year 8s one.
