Ben and Shannon's Hand Challenge

During writing and science we did a challenge that was called "give me a hand". We had to make a poster that explained what are hands and how do they work. Our question was "why are our hands some of the most important tools we have?". We used QR codes to help us find our answers. We learnt that we need thumbs to help us do things like picking up things, if we have no thumbs it is hard to do stuff.
