Simple Machines

Can you open a screw without a screw driver? Or cut a string without scissors? It might be possible but it is very hard. That is why we use different machines in our daily life. A machine is a tool used to make work easier. Simple machines are simple tools used to make work easier. Compound machines have two or more simple machines working together to make work easier.


Material and instructions:
In this project you will design and perform experiments to demonstrate how different machines make work easier. You will make samples of simple machines and calculate the mechanical advantage of a simple machine that you test.
