Measuring the volume of irregular shaped objects

This week Ashmansworthy class have been learning about volume and capacity in maths. They used the formula v=lxbxh to calculate the volume in cubic centimetres of cuboids. But how could we measure the volume of other objects like dinosaurs, rocks or apples?

The children discussed this problem and discovered that because 1ml of water has the volume of 1 cubic centimetre, if they placed an object in water and calculated how much water was displaced, that would be the volume of the object immersed.

The children had to estimate the volume before measuring it, and then record their results in a table.
