Cogs

Yesterday we learned about cogs. We made two cog wheels and we brought it both together. When we brought it together, we also had to make a hole so the pencil can go through. When we put the pencil through the hole we could spin them. When we spin one wheel both cogs moved. Mr. Ramkolowan taught us how to make the cogs. We made the cogs out of cardboard. Then we drew teeth and cut it out. We all had different sizes of cogs. Tamim and Melissa had the biggest cogs and Pareata and I had the second smallest cogs. It is fun to make cogs.
