Science workshop with WGSB
On Wednesday we went to a science workshop. We did a lot of work with Mrs Smith (who was from Wilmington Grammar School for Boys) and then we had to get in teams of three. Together we had to make a K’nex car and then use air energy to fire it up.
First, we had a demonstration of how it works. You pump air in a plastic box so the air can’t escape and then you make the air shoot out into a paper tube attached to the car and the car will go really fast. Our challenge was to make it go in a straight line without turning but mine turned 90 degrees!
When we started Daniel and I made an ok car. It reached up to the 4 meter mark but because of the big wheels it didn’t go far enough.
To improve the car we removed weight and then the tube blew off because we didn’t Sellotape it strong enough. In our last try fortunately our car reached the 9 meter mark, me and Daniel did quite well! It was really fun! The fastest car was Yuqi’s which went 12 meters!

On Wednesday the 19th March 2014 class 4J went for a science workshop in the stage hall. We were challenged to build a car out of K’nex that can go in a straight line and go the fastest.
First, we all got grouped into three’s. I got grouped with Mie and Poppy. We started with big wheels and made it look pretty, but when we tested our car, the tube took off without the car! Next, we tried a less beautiful design but it didn’t go far. Time was nearly up but we didn’t give up. We made a glider design with small wheels. They pumped up the paper tube and off it blew in a straight line. We didn’t get 1st, 2nd or 3rd but I really enjoyed it. The Lady that came was called Mrs Smith and some students came too.
