Assessment
Use 2.3 Grading the Molecules in Cells Quiz to grade student ideas about the materials in food. Use this quiz to determine if you need to revisit Activity 2.2, or if students are ready to move on to Activity 2.4 and Lesson 3. Because this is the Foundational Knowledge and Practice Stage of the unit, it is ok to evaluate student ideas at this point to see how they do and do not align to scientific ideas.
