How many bones?

We were interested to find out how many bones we had in our hands.  So, for Halloween, we decided to make Xrays of our hands to find out.

First we looked carefully at our hands as we bent all our fingers like claws - we could see and feel that there was a little joint joining two little bones together at each bend.

We carefully drew around our hand, and then made a mark to show where each joint was.  Then we coloured in each hand with wax crayon, but left a space between each joint which we painted with vegetable oil.  When the pictures were set up by the window, the sunlight shone through the oil so you could count the 'bones'.  How many can you count?
