Lifting someone with his thumb

So one day Mr Hendricks came into room eight and said he had a challenge for us.  He said that he was going to lift the heaviest person in room eight. We didn't believe him until he showed us. While we were out side he came out with a lever and a long piece of wood. He put the long piece of wood on the lever and told Sive to get onto the other end. When Sive got on the other end he pushed the wood down with his thumb. We were so amazed how he used a simple machine to life the heaviest person in our class with his thumb.   

Simple machines

The focus for this term is simple machines. So since our topic is simple machines, my teacher said to make a simple machine of our own at home using a pulley or wheel and axle. In my simple machine I used two bobbin's to act a two pulleys. My simple machine I have created is a old school scale, I also used materials that I had a home. Here are some of the things I used to make my simple machine:

1. Wooden hanger

2. One Toilet roll

3. Two bobbin's

4. Two Plastic cups

5. Five key rings

6. Different sizes of rope

7. A small piece of salafain

Making this simple machine was really hard but I got help from my aunty. So without her help I wouldn't have completed my simple machine. When I was done with my simple machine I decided to help a friend with her simple machine, she made a well with a pulley too.
