Resources Provided

Setup

Print one copy of the4.2 Explanations Tool for Potato Cellular Respiration for each student. Return students’ completed versions of the 3.5 Evidence-Based Arguments Tool for Plants for review. In this activity, your students will need to use the Three Questions Explanation Checklist on the back of the Three Questions Handout. Be sure to have this available to students, and see the notes in the Modifications at the end of the Activity for ideas about how to use it.

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 Tools for Potato Cellular Respiration to grade your students’ work on the 4.2 Explanations Tool for Potato Cellular Respiration. At this point in the lesson, students should be held accountable for correct answers.

Tips

  • Make sure students understand that the chemical energy in glucose (not the 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 Handout. They play a central role in all Carbon TIME units.
