RDS Primary Science Fair 2013 – 4th Class

Over the next few days we will update you and tell you all about the project we presented at the Science Fair. We were very lucky to be picked to take part and we worked very hard.

Last week in 4th class we went to the Young Scientist Fair in the RDS to present our project on pulley systems. We left school at 7:45am on Friday 11th January and returned at 5:30pm. We had a fantastic day and learned so much.

We will tell you a little bit about our project now.

Our Project

Firstly Miss O’Donnell gave us a set of questions. We were split up into groups and had to discuss answers to the questions. You can see the questions and answers on our display.

After that we discussed it as a class, we watched a video about single fixed pulleys and single movable pulleys.

Then each group were given six blocks. We had to try to move the big red block that we were given. After that we had to stack two blocks on top of the red block and try to move it without them falling. We couldn’t do it but then a boy in our class called Trofim came up with the idea of the pulley.

Some people made homemade pulleys and then we found out if you use a thick rope on the pulley it would fall off the spool .Then there were five people that went out with a teacher and tried to find everyday objects that used pulley systems.

We watched this video about NASA. We saw that even NASA uses pulleys that can hold up to 300,000 kg and they have 3 of them .They use the pulleys for pulling the rocket up and down .The rocket weighs 200,000 kg

We hope you enjoy our project as much as we did!
