Being creative with cams!

This week, we will be creating our own moving time machines! Before we start to make our machines, we've been looking at different cam mechanisms to see how they work and what the different parts are called. You can explore how the shape of the cam affects the movement below...

We then used cardboard, split pins and straw to make our own simple cam. We tested it to see if it worked and to see which movement it created. We discovered that rounded corners and gradual slopes worked best!
