Now that we understand the structure and function of bones, our kindergarten classes conducted an experiment in which they played a peg game using just one hand. For the first round, the students could use their hand as normal and were able to place as many pegs as possible in 20 seconds. For the second round, we wanted to see what it would be like to only have one bone in our fingers and thumb. We placed tape around our fingers so that they could no longer bend and played the game again. The students concluded that we need so many bones in our hands so that they can move more freely and help us pick things up.
