This lesson teaches students about inverse variation by exploring the relationship between the heights of a fixed amount of water poured into cylindrical containers of different sizes as compared to the area of the containers' bases.

The purpose of this task is for students to interpret and highlight features of functions using contexts. This task provides opportunities for students to practice skills they have already learned as well as solidifying their knowledge of features of functions. This task first asks students to make observations from a graph. There are several observations to make and by having students make these observations, they are accessing their background knowledge as a way to prepare for this task. In the following sections, students solidify their understanding of domain and distinguish between the domain of a function and the domain of a situation. They also use function notation to interpret the meaning of the situation.
