3. The graph shows the volume of air in a balloon as you blow it up, until it pops. What are the variables? Describe how the variables are related at various points on the graph Objective: SWBAT represent mathematical relationships using graphs. Variables: Volume & Time Volume increases each time you blow It stays constant each time you pause to breath When the balloon pops in the middle of the 4 th blow, the volume decreases to 0. Read the titles. Axis titles tell you what variables are related. The graph itself represents the relationship as the variables change.

It begins to fall quickly until the parachute opens, after whih if falls slowly back to Earth.

8. What are the variables in the playground scenario? Consider quantity of children Time of day temperature There are 6 children playing in a playground. Is the number of children playing a constant or a variable quantity? The # of children is a variable quantity because it will change. What other variables might affect the number of children at the playground? Time of day; temperature… Objective: SWBAT represent mathematical relationships using graphs.
