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.
Objective
1. Students use proportions to represent quantitative relationships.
2. Students use the transitive property of equality to find the relationship between three variables.
3. Students express proportional relationships using mathematical notation.
