1. Concept mapping. In small groups students discuss how ideas throughout the unit relate. They make unit concept maps indicating connections among ideas and then provide peer critique/feedback on others concept maps.
2. Whole-class debrief. Students summarize the missing links they saw on the concept maps.
3. Summative assessment. Students use the concept mapping activity to write a revised story of the forgotten strawberry.

Discussion Questions:1) What kinds of student thinking are afforded by this lesson? 2) How might you tweak this lesson to help students differentiate between major ideas (cellular respiration) and minor ideas (enzymes)? 3) Create an explanation rubric and evaluate 9 students revised stories of the forgotten strawberry, detailing partial as well as complete understandings.
