Plants Activity 4.1 Differentiation

  • Strategic grouping with strong speakers
  • Build models for students to copy
Extending the Learning
  • Plants do not give off CO2 at night only! Plants perform cellular respiration 24 hours a day. Encourage students to think about why we observed plants giving off CO2 at night only, but we were unable to detect their CO2 during the day.
  • Have students compare the chemical reaction for combustion and the chemical reaction for cellular respiration. Ask: What do you notice about these two reactions? What do they have in common?
