Homework:
LAST DAY FOR ANY PAPERS!!!
I can…
Explain matter transfers when plants grow in the light and dark.
Collect your lettuce plants.
Read “Harvesting Your Plants” sheet at your table.
Summarize the first steps of the harvesting process. What will you be doing today?

13. Explaining Your Results for Plants in the Light/Dark
What patterns did you see for color changes in BTB for plants in the light or dark?
What can we conclude about CO2? What do plants in the light or dark do to carbon dioxide in the air?
How can we explain these results with answers to the Three Questions?
Use Slides 7-10 to discuss the students’ explanations for what plants in the light do when they absorb CO2, reminding them that a good explanation has to include answers to each of the Three Questions.

14. The Movement Question Where are atoms moving from?
Where are atoms moving to?

Use Slides 2-6 of the Lesson 2.2 Modeling Photosynthesis Presentation to show students how materials are moving in and out of plants, including:
A whole plant view (Slides 2-4)
A leaf scale view (Slide 5)
A view of a leaf cell (Slide 6).
Tell students that in this Lesson they will learn how plants can make sugar (or glucose) from inorganic materials: carbon dioxide and water.

15. Which atoms and molecules move so that plants can do photosynthesis?
water
carbon dioxide
oxygen
glucose

19. What is Photosynthesis?
Photosynthesis is the secret of plant growth.
Plants do photosynthesis so they can grow (gain biomass).

Use Slides 7-10 to overview the main details of photosynthesis, including the Carbon Question and the Energy Question, which students should ideally be able to answer after the molecular modeling in the next few steps.

20. Photosynthesis happens when light energy from the sun, carbon dioxide, and water are used to make sugar and oxygen.
