Today the children learnt what a gear system is and how a simple gear system works on a bike or inside a clock. As part of the lesson, the class made their own gears using templates, card, split pins and a lot of hard work! After lots of careful cutting, sticking and placing of the gears in the right position, they were able to demonstrate a 2:1 ratio gear system. Well done Upper School!
