Target Student Performance
Students use molecular models to explain how carbon, oxygen, and hydrogen atoms in glucose and oxygen molecules are rearranged into carbon dioxide and water in a potato plant’s cells.
Resources You Provide
- (From previous lesson) Students’ unanswered questions they shared in Activity 3.5 Evidence-Based Arguments Tool for Plants
- (From previous lesson) 3.5 Evidence-Based Arguments Tool for Plants
- molecular model kit (1 per pair of students)
- scissors (1 per pair of students)
- twist ties (at least 12 per pair of students)

Setup
Prepare one model kit, one Molecular Models 11 x 17 Placemat, one pair of scissors, and one set of the Forms of Energy Cards for each pair of students. Print one copy of the 4.1 Molecular Models for Cellular Respiration Worksheet > for each pair of students. Prepare a computer and a projector to display the PPT. Retrieve the materials from Activity 3.5. This may include PPT slides from the lesson in which you typed students’ unanswered questions or a photograph of their unanswered questions.
