Students will analyze results from the lab to interpret whether their hypothesis was correct regarding the relationship between photosynthesis and cellular respiration
Students will work collaboratively to learn the stages of photosynthesis (Light and Dark Reactions), the role of energy carrying molecules, and the ETC
Students will complete a virtual lab to prepare them for the next days' case study
Virtual Lab Homework
Student #1- The light reactions
Student #2- The Calvin cycle
Student #3- Energy carrying molecules of photosynthesis
Student #4-The specifics of the Electron Transport Chain
Students will be able to explain the effects certain variable have on photosynthesis rates
Students will explore how genetic modification in tomato plants helps them withstand stress by ensuring photosynthesis is not hindered.
Students will explore the controversial topic of GMO's and formulate an educated opinion
o SWBAT solve a case study to apply knowledge regarding factors that affect photosynthetic rates.
Explain how your results demonstrate that photosynthesis and cellular respiration depend on one another.
Small Group Discussions
o SWBAT explain and draw diagrams that summarize the two phases of photosynthesis, the light reactions and the Calvin cycle.
Naturally occurring food and fuel contain complex carbon-based molecules, chiefly derived from plant matter that has been formed by photosynthesis. The chemical reaction of these molecules with oxygen releases energy; such reactions provide energy for most animal life and for residential, commercial, and industrial activities.
“Collision theory” provides a qualitative model for explaining the rates of chemical reactions. Higher rates occur at higher temperatures because atoms are typically moving faster and thus collisions are more frequent; also, a larger fraction of the collisions have sufficient energy to initiate the process. Although a solution or a gas may have constant chemical composition—that is, be in a steady state—chemical reactions may be occurring within it that are dynamically balanced with reactions in opposite directions proceeding at equal rates.
The main goal is to teach the content through problem solving and cooperation so that students can disentangle tough issues collaboratively with their peers.
Students will understand reactants, products, where they came from, where they go, and how photosynthesis and cellular respiration are related.
In the interest of genetic engineering and agricultural applications, the authors analyze the relative importance of genes that control both metabolic and light reactions as well as the structure, arrangement, and orientation of photosynthesis.
In this experiment Ingenhousz demonstrated that plants are dependent on light and their green parts for nutrients and energy.

Concept and Attitude/Application
o SWBAT relate the reactants and products of both photosynthesis and cellular respiration by conducting a mini lab experiment.
Day Two: The Light and Dark Reactions of Photosynthesis, ATP/NADPH, and the Electron Transport Chain
Day Four: Hot Topics in Photosynthetic Research
Four teaching options:
creative writing narrative
Students will condense what they know about photosynthesis creatively to teach third grade students.
Students will blog to practice for the essay test.
Day Five: Role Reversal; Teaching Photosynthesis Creatively and Clearly
o SWBAT compose a narrative of what life would be like for humans if we could carry out photosynthesis and share it with a third grade student.
PETERSON/ECHS Describe the light reactions of photosynthesis and, for both a C3 and a C4 plant, trace the path of a carbon dioxide molecule from the point at which it enters a plant to its incorporation into a glucose molecule.
The basic equations of photosynthesis and cellular respiration;lab discovering the relationship between their reactants and products; Light and Dark reactions, ETC, ATP and NADPH; Case Study on GM tomato plants; research; teaching photosynthesis to elementary children.
This unit in bioenergetics will equip students to write the equation and draw the light independent and light dependent reactions of photosynthesis.
PETERSON/ECHS Describe the similarities and differences between the biochemical pathways of aerobic respiration and photosynthesis in eukaryotic cells.
. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and release oxygen. (Boundary: Further details of the photosynthesis process are not taught at this grade level.)
