Resources Provided

Setup

Print one copy of the 4.4 Explanations Tool for Potato Photosynthesis for each student. 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. Prepare a computer and a projector to display the PPT.

Directions

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

Assessment

Use 4.4 Grading the Explanations Tools for Potato Photosynthesis to grade student responses. 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 lesson they are finding difficult. Use Grading the Matter and Energy in Plants Graphic Organizer to grade the graphic organizer.

Modifications

The Three Questions Explanation Checklist on the back of the Three Questions Handout can be used to scaffold students’ explanations in many ways.

  • Students refer to the checklist as they are constructing their explanations.
  • Students use the checklist as they are sharing and revising their explanations with a partner.
  • Students use the checklist to critique and revise their final explanations.
  • Students use the checklist to critique the example explanations for each unit.
  • Students use the checklist to create and/or evaluate a whole-class consensus explanation.

We recommend using this checklist with a gradual release. As students improve in their ability to write their own explanations, they may rely on the checklist.
