Effect of Exercise on the Body

Ask students to do one of the following activities:
1. Walk up and down a flight of stairs in school.
2. Run or job in place
3. Do sit-ups for 2-3 min
4. Think about a time when they played a strenuous sport such as
basketball or soccer, or had to run for the bus.
In their groups have students discuss the question below:
What are you feeling?
Then: Draw a picture that shows what happened inside the body
during this exercise. You might suggest that students particularly pay
attention to their heart, breathing, and how their muscles feel. Label
drawings.
Discuss drawing in group.
Now share drawings and ideas with the whole class. Remember, no
answer is right or wrong at this time. It only explains what students are
thinking at the beginning of instruction.
