SAC 2 Revision
Task 1:
Consider the normal human body temperature, everyone will have a slightly different average temperature but all should be within the 36.2-37.4 degrees Celsius. Over the next few days record your own body temperature at points of rest to obtain a baseline measurement. Consider recording your temperature shortly after exercise and right as your wake up.

Questions:
What can change the set point for body temperature?
How does stress affect body temperature?
What happens when you walk into the freezer aisles of a grocery store or a room that has the air conditioning set very cold?
How does your body react (shivering, goosebumps) and how might this affect your body temperature?
What role might fever play in fighting infection?
Have students generate list of signs and symptoms they have when they get a fever. Discuss how these symptoms are different from how you feel after you've done a little exercise.
Task 3:
What happens when you sweat? Why wouldn't you want to exercise outside on a very hot day? Complete this activity to explore the function of sweat.
Blow on your forearm. How does your skin feel?
Place a few drops of water on your forearm and rub it just a little bit.
Blow on the wet spot.
Does your skin feel any different than when you blew on it without the water? Discuss how blowing on the wet skin seemed cooler than when you did the same on dry skin. How is this helpful to your body when you have a fever?
Task 4:
Make a graphic organizer/flow chart to demonstrate the factors involved with maintaining body temperature
