Homeostasis WebQuest
Put your name on a sheet of notebook paper. Then complete the following tasks. You will have one class day to complete Parts A to E.
Part A- Homeostasis Overview and Body Temperature Regulation:
Watch an introductory video on homeostasis at Khan Academy: Homeostasis at Khan Academy
(You can pause and rewind the video at any time.)
Answer the following questions:
1. Name TWO things the girl's body did to maintain homeostasis after she became too cold.
2. Name TWO things the girl's body did to maintain homeostasis after she became too warm.
3. Identify two other areas in which the body needs to maintain homeostasis.
Part B- Blood Sugar Regulation:
Visit Shmoop.com's article on homeostasis: Shmoop Homeostasis Article
Complete the following:
4. Find the diagram showing 5 parts of the Circle of Homeostasis. As best as you can, draw this diagram showing the 5 parts and the fulcrum (seesaw). You do not need to add in the black and white text boxes, just focus on the colored part of the diagram.
At the bottom of the page is a section called Failure of Homeostasis which discusses what can happen if homeostasis goes wrong.
5. Identify the disease discussed in this section.
6. Briefly discuss what causes the disease.
Part C- pH Regulation:
Visit the McGraw-Hill website section on homeostasis: McGraw-Hill Summary of Homeostasis
Scroll down to the section on Control of pH and read it carefully. Then answer the question:
7. Identify the three ways the pH of the body is regulated.
Part D- Blood Pressure Regulation:
Read the answer to the question "How is my blood pressure normally regulated?" on How Stuff Works.
8. In one sentence, describe how your brain responds when your blood pressure drops too low.
9. In two sentences, describe the two ways your kidneys regulate your blood pressure.
Part E- Water Balance Regulation:
Watch the Bozeman Science YouTube video on Osmoregulation.
10. What hormone has an effect on the nephrons in the kidneys and prevents excess water from being excreted?
