School expo

On Friday we had a school expo. Every class on the senior side had to create a simple machine to show at the expo. I made a care using a wheel and axle. It was fun making this and I hope to this again. 

Simple Machine Toy

For the past few days our class has been busy making simple machines. The only two simple machines we could use to make our project was a pulley and a wheel and axle. We had to make our own version of a pulley and a wheel and axle. To make my simple machine I used paper, cardboard and toothpicks. I did not have an idea of how to make my simple machine but then I saw a image on google similar to my one but they did not use paper.
