Today we investigated to find out "What is the point of a joint"?
We made joints out of straws, sticks, ping pong balls, playdough, wool, ice block sticks and rubber bands. We identified where the joints are in our body and we looked around the school for other mechanisms that have joint like actions.
Did you know, the door has three joint like mechanisms....the handle, the hinge and the door stopper.
Did you know an ipad, chrome book and laptop have joint like mechanisms?
Did you know the toilet has a joint like mechanism on the seat and lid?
