Class began with the following entry task:

Use the Item Bank (H20, CO2, ATP, O2, C6H12O6):

  1. Which are inputs of cellular respiration?
  2. Which are outputs?
  3. Write the equation for cellular respiration

The entry task launched our brief review of cellular respiration, photosynthesis, and chemical potential energy stored in glucose and transferred to ATP.

After taking notes, the discussion transitioned to a recognition that while humans can eat glucose directly by consuming plants, humans can also obtain energy by eating other animals that eat plants.  For example, when we eat beef, we are ingesting protein and fat (lipids) produced by a cow that ate grass.  That led us to the Biological Molecules Crash Course video (below) and the associated worksheet.  Each student was assigned one question from the handout to answer, and then students combined answers in a class share-out at the end of class.  A completed copy of the worksheet is also provided below.

November 8 – Updated

Our study of biomolecules continued with students working in groups of three to read about carbohydrates, lipids, and fats.  Each student read one section, and then all three shared what they learned with the other students in the group so that each student was able to complete one worksheet.  At the end of class, we re-grouped and created the summary table shown below:
