Archimedes – Displacement

This week, we have been learning about the famous Greek mathematician, Archimedes, in particular, his theory of displacement.  We watched what happened to the water level as Archimedes filled up his bath and got into the tub.   We then described this using a line graph.

We also investigated how we could find out the volume of a marble, by using our knowledge of displacement.  We soon realised that one marble didn’t alter the volume of the water much, so we tried more marbles, then divided the total amount of water displaced by the number of marbles.
