  1. Activity 39: Cells Alive – Cellular Respiration Record the following experiment in your Science notebook.

  2. Activity 39 Background Knowledge Add to Important Vocabulary Cellular Respiration: The process that cells use to break food down into ATP or energy.

  3. Question Do cells yeast cells release produce carbon dioxide through cellular respiration?

  4. Research • Complete the following sentences in your notebook: • Yeast is… • Cells take in oxygen and release _____________ • When carbon dioxide is present, BTB will _______ • ___________________________________________

  5. Hypothesis • Write a hypothesis for the • question we are investigating. • Be sure to include: • I think… • Because…

  6. Procedure (copy into your notebook) 25 drops yeast 10 scoops sugar 25 drops yeast 50 drops water 2 drops BTB 25 drops water 1 drop BTB

  7. Understand the experiment

  8. Data Table

  9. Initial Observations This is what our experiment looked like when it was first set up. Make observations and record them in your “initial observations column.

  10. Final Observations: This is what our experiment looked like after 2 hours. Make observations and record them in your “final observations” column.

  11. Conclusion Answer the original question in your notebook BASED ON THE EVIDENCE YOU COLLECTED. You must support each claim you make with evidence from this experiment or research. SLE #8: I can use evidence to develop descriptions, explanations, and predictions.
