Examine the relationships between capacities of various containers. Look at three containers that may have different diameters, heights and shapes. Fill a container and squirt liquids between the containers to establish the proportional relationship. Work out the third 'unlinked' relationship from two known relationships. Express relationships using mathematical notation, for example where a=7b and c=5b, then 5a=7c. This learning object is the last in a series of five objects that progressively increase in difficulty. Some objects in the series are also packaged as a combined learning object.
