As a class we read 'Balancing Act' (independent reading for some students, shared reading with the teacher for other students) a School Journal article about a Wellington artist, Stavros Kyriakides, who makes balancing rocks and driftwood sculptures on the beach. 

To get us started in how to find the centre of gravity we looked for equipment on hand: a pencil - here are some pics from class this morning.  The children were extremely successful in finding the centre of balance of a pencil.  But, to make it harder, the students were then given a peg to put on one side of the pencil, and the children found out the centre of gravity had changed and they could no longer balance the pencil on their finger from the middle of the pencil and they had to shuffle and shift the pencil to find its 'kiss point' (Stavros Kyriakides' turn of phrase to find the point of balance on objects that are balancing on each other).
