  1. Carbon: Transformations in Matter and Energy Environmental Literacy ProjectMichigan State University Plants UnitActivity 4.4 Explaining How Plants Make Food: Photosynthesis

  2. Plants Unit Map You are here Lesson 2: Foundations: Zooming into Organisms Lessons 4 & 5: Explaining How Plants Make Food, Move, Function, and Grow Lesson 3: Investigating Plants Lesson 1: Pretest and Initial Ideas Lesson 1: Pretest and Expressing Ideas Lesson 6: Explaining Other Examples of Plant Growth and Functioning Inquiry (up the triangle) Application (down the triangle) Model Pre Lesson: Investigation Set-Up Evidence-Based Arguments Observe Coach Models Fade Post test Maintain Predict & Express Ideas Establish the Problem Pre Lesson Pretest Found-ational Knowl-edge and Practice Next Unit Photosynthesis Biosynthesis Cellular Respiration Patterns Plants gain mass (more). Soil loses mass (less). Plants take in CO2 in the light. Plants release CO2 in the dark. Observations Data from mass of plants growing from seed. Data from plants in the light and dark with BTB.

  3. Revisit your arguments Think about what you know now that you didn’t know before. What have you learned?

  4. Plants make their own food Materialsfor growth:Biosynthesis Food To Cells Energy:Cellular respiration

  5. Constructing explanations Consider the following as you construct your explanation: Evidence from the investigation What you learned from the molecular modeling activity Three Questions Handout

  6. Comparing Ideas with a Partner • Compare your explanations for each of the Three Questions. • How are they alike? • How are they different? • Check your explanation with the middle- and right-hand columns of the Three Questions handout. • Consider making revisions to your explanation based on your conversation with your partner.

  7. The MatterMovement Question Where are atoms moving from? Where are atoms moving to?

  8. Which atoms and molecules move so that plants can do photosynthesis?

  9. How do glucose water, carbon dioxide, and oxygen move for a plant leaf to photosynthesize?

  10. Matter Movement Do you have: • an arrow showing carbon dioxide or CO2 going into the plant’s leaf cell? CO2

  11. Matter Movement Do you have: • an arrow showing water or H2Ogoing into the plant’s leaf cell? CO2 H2O

  12. Matter Movement Do you have: • an arrow showing glucose or C6H12O6 leaving the plant’s leaf cell? CO2 H2O Glucose

  13. Matter Movement Do you have: • an arrow showing oxygen or O2 leaving the plant’s leaf cell? CO2 H2O Glucose O2

  14. The MatterChange Question How are atoms in molecules being rearranged into different molecules inside a potato cell during photosynthesis?

  15. Plants make glucose fromcarbon dioxide and water in their leaves.

  16. What happens inside the leaf cell as it photosynthesizes? Chemical change

  17. Matter Change What is the name of the chemical change that allows cells to make food? Photosynthesis Write the chemical equation for this change: 6 CO2 + 6 H2OC6H12O6 + 6 O2

  18. Matter Change What molecules are carbon atoms in before the chemical change?   Carbon dioxide or CO2 What other molecules are needed? Water or H2O What molecules are carbon atoms in after the chemical change? Glucose or C6H1206 What other molecules are produced? Oxygen or O2 Chemical Change

  19. Energy Change What forms of energy go into this chemical change?   Light energy What forms of energy come out of this chemical change? Chemical energy Energy Transformation

  20. Matter Movement What happens to glucose made by photosynthesis? Glucose moves from a plant’s leaves to allof its cells.

  21. Telling the Whole Story Question: How does a cell in the potato plant get food to a cell in its root? • Does your story include these parts? (Check the back of the Three Questions Handout.)

  22. How have your ideas changed? • Gather together your process tools for the unit (Expressing Ideas Tool, Predictions Tool, & Evidence-Based Argument Tool). • How have your ideas changed related to: • Scale? • Movement? • Carbon? • What do you know now about how plants make glucose that you didn’t know before the investigation?

  23. Revisit unanswered questions Which unanswered questions can you now answer with what you understand about photosynthesis? Which questions are left unanswered? Do you have any new questions to add?
