What the teacher will do:
a. Questions to engage student thinking during activity:
1. What do you think is the reason for the color change when you used a
straw to blow into the uncovered test tube
2. What is the purpose for covering one of the test tubes with aluminum
foil

What the teacher will do:
a. Use the following questions to engage student thinking after the activity and
to connect concepts of this activity to the NGSSS.
1. Did the color of the cabbage indicator change when you exhaled into the
test tube Explain why.
2. Did the color of the cabbage indicator change in the test tube that
contained the radish seedlings Explain the reason
3. Compare the reaction that occurred in the test tube that contained the
radish seedlings with one that occurred in the test tube into which you
exhaled. How are they similar
4. Did cellular respiration occur in this experiment Explain.
5. Was your hypothesis correct or incorrect Explain your answer in detail.
6. Why is the process of cellular respiration common to all forms of life
7. Why do most living things take in oxygen
8. Where in the cell does cellular respiration take place
9. What is the interrelated nature of photosynthesis and cellular
respiration
b. The students should complete a formal laboratory report.
