To finish our Circus topic, we spent our last week before the holidays creating our very own moving circus performers. We learnt about simple machines and mechanisms. We began by experimenting with levers and sliders and figuring our what parts of the body have joints that help us move. We then put our knowledge to use by designing and creating performers. We joined card, added split pins and handles. We learnt that our mechanisms needed a force in order to move, which we found out were pushes and pulls. We then wrote explanations about how our creations work!
