What I learnt about Cogs
Cogs are used in toys.
So yesterday we made a cog ourselves. We had to buddy up with a partner and I chose my best friend obviously. We were given a piece of cardboard to make our cog. We drew a perfect circle then we drew the teeth and cut out the shape of the cog. It didn't take time to finish our project. We tried them out and they worked perfectly.
They are shaped like a circle and have teeth on the outside.
Cogs can be used for movement on any object, like a toy.
