Yesterday I learnt how cogs work. I have also learnt how to make cogs out of cardboard. I used a
ruler, pencil and a scissors. First I cut out the cardboard in a circle. Then I drew another circle in the middle. I cut the teeth of the cog on the circle. After I finished I put in a pencil in each cog. Mr Ramkolowan took a photo of Etai and me with our cogs. Etai’s cogs was big and my cog was small. I was holding the cog and Etai was moving the other cog around and my cog was turning.
