Differentiation Provide sentence stems for discussion and filling in the Explanations Tool Work through the tool as a class and provide sentence stems for final explanation Hand out and refer to Example Animals Explanation Handout when working on the Explanations Tool Refer to the word wall for questions on Cellular Respiration related vocabulary Refer to the Assessing the Animals Matter Tracing Tool to support students further 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 less. Extending the Learning If there are still unanswered questions about cellular respiration, watch this video. https://www.youtube.com/watch?v=4Eo7JtRA7lg Many traditional biology curricula include more depth about the steps in cellular respiration, mitochondria, and the role of ATP in cellular metabolism. While this level of detail is not included in the Next Generation Science Standards and is not necessary for the storyline in this unit, this would be an appropriate time to add those lessons.
