Resources Provided

Setup

Print one copy of the 4.2 Explanations Tool for Cow Cellular Respiration for each student. Return students’ completed versions of the 3.3 Evidence-Based Arguments Tool for Mealworms Eating for review.

Directions

1. Use the instructional model to show students where they are in the course of the unit.

Assessment

During the class, circulate while students are comparing their explanations. Listen to see if they are able to explain cellular respiration at both the macroscopic and atomic-molecular scales. Use 4.2 Grading the Explanations Tool for Cow Cellular Respiration to grade student responses. This worksheet has “grading” in the title (instead of “assessing”) because at this point, students can be held accountable for correct answers. If students are still struggling with these concepts, you may want to revisit parts of the activity they are finding difficult.

Tips

  • Make sure students understand that the chemical energy in glucose (not glucose itself) is converted to heat and light energy.
  • Make sure that students discuss and understand all three columns of the Three Questions 11 x 17 Poster or Three Questions Handout.They play a central role in all Carbon TIME units.
