5. Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed

Rain Barrel Investigation
So, we have this rain barrel that holds 50 gallons of water and it was completely full during the last rain.
After the rain I emptied the rain barrel because it is getting cold and I did not want the water inside the barrel to freeze.
Below i have documented how many gallons were in the rain barrel and how long it took for the water to drain out.
Find the rate at which the water was leaving the barrel at during each timing.
Why are the rates different?
What is slope?
How do I find slope?
Mario teaches me how slope and rate are connected!

Proportional Relationships in Action
Student created examples of the relationship between distance and time.
