The boys have completed a number of activities to help them to understand that even though we can't see a force, we can see its effect. Over the sessions, I've been impressed with the number of boys who have begun to use the correct vocabulary and in the right context.
We made little pecking birds which showed gravity pulling the bird down, and friction between the rubber band and the piece of straw which created the birds pecking effect. We also made a climbing man where friction helped the man climb up the string with a simple pull from the bottom. Then gravity took over and let the man fall to the bottom, all ready to start his climb again. Great to see the boys really engaged in some simple activities that reinforce their new learning.
