These past few weeks the primary children have started to put things to motion, while keeping in mind the lessons learned about balance. They have enjoyed discovering with their "spinners" and "twirlers" that in order for something to spin in a balanced fashion the mass needs to be centered and it has to rotate fast. This past week they have created rolling systems with a straw as the axle and different sized disks as the wheels. The children were challenged to find a design that would create a "wobbly roller" and a design that could "turn a corner". The students had a lot of fun with these challenges and all discovered that the size of the wheels effected the rotational motion more than weight or mass. Hope you enjoy the pictures! Miss Tracy
