Look at the graph below. Which of the following describes a possible explanation of the change in population between 1980 to 1982?

The population decreased from 1980 to 1982 because there were more wildebeest competing for a limited supply of food.

The population increased from 1980 to 1982 because there were few wildebeest competing for an unlimited supply of food.

The population increased from 1980 to 1982 because there were more wildebeest competing for a limited supply of food,

The population decreased from 1980 to 1982 because there were few wildebeest competing for an unlimited supply of food.

Look at the graph below. Based on the rates of change, in which time period 1980-1982 or 1986-1991 was there more likely to have been a drought?

1980-1982 because the rate of change was more negative and more wildebeest were dying.

1986-1991 because the rate of change was more negative and more wildebeest were dying.

1980-1982 because the rate of change was less negative and more wildebeest were dying.

1986-1991 because the rate of change was less negative and more wildebeest were dying.

How did what we figured out today help you better understand your conservation profile?

Scientists have established the carrying capacity of wildebeest at 1.3 million in the Serengeti ecosystem. They predict that the population will fluctuate around this number if conditions in the ecosystem stay the same. Which of the following graphs represent the most likely outcome for the wildebeest if the total area of the park decreased and all other components of the system stayed the same?

Option 1

Option 2

Option 3

Option 4

How did mathematics and computational thinking help you make sense of the carrying capacity of the wildebeest population?

How did the use of rates of change help you explain the lesson question: How does food affect the population size?

Name one student who helped you learn today. What did they do?
