IC3 Lessons 1-3

In Lesson 1, during 1 minute of exercise (running/jogging in place), we used a pedometer to measure...

• our heartbeat

• our calories used

• our carbon dioxide level in our breath

• our breathing rate

In Lesson 1, after 1 minute of exercise (running/jogging in place), we observed all of the following EXCEPT:

• our heart rates increased

• our skin temperature increased

• our breathing rate increased

• our carbon dioxide levels increased

What did we learn about the temperature of the skin during exercise?

• Skin temperature increases in order to keep the person from dying from extreme cold.

• Skin temperature increases in order to warm up the muscles.

• Skin temperature decreases to send more blood to the muscles.

• Skin temperature decreases to send more blood to the feet.
