Lesson 5: Homeostasis in Other Body Systems Preview CT-STEM

Evaluating the claim: human body systems maintain homeostasis

Even though you and your classmates completed different investigations, all of them should have provided you with experimental evidence to support the claim that living systems maintain a stable internal environment even as the external environment changes.

A secondary claim could be made that living systems maintain stable internal conditions in response to changing external conditions.

Look at the graphs below to help you answer the following questions.

Questions

Please answer the questions below.

Question 5.1

What similarities do you see in the three graphs? Be as specific as possible - refer to things like time, internal/external conditions, etc.

Question 5.2

Using data from the graphs above (or the ones that you created), determine the set point for the following internal conditions:

Question 5.3

Does the evidence in the graphs support the following claim? Use scientific reasoning to support your answer.

Living systems maintain a stable internal environment even as the external environment changes.

Question 5.4

Does the data in the graph support the following claim? Use scientific reasoning to support your answer.

Living systems maintain stable internal conditions in response to changing external conditions.

Question 5.5

Which of the claims from the previous questions is best supported by data in the graphs? Use evidence to explain your reasoning.
