Havea- Thumb lifts

Last Friday Mr Hendricks proved that he could lift the heaviest person in our class with his thumb. He lifted Sive with his thumb with one of the simple tools which was a lever. When he lifted him he explained how he did it and then he lifted the teacher.

Harrison - What goes up ..must come down

We had to make a simple machine to show our learning about our topic study. I decided to make one using pulleys which is a wheel with a grooved rim around which a cord passes, which acts to change the direction of a force applied to the cord and is used to raise heavy weights. Mine is called "What goes up... must come down". It took a while to make but was deffinetly worth it.
