Energy Flow Through Photosynthesis Process
Grade 7 Science Understanding How Plants Convert Energy I can explain the process of photosynthesis
Think About This...
Where does a plant get its energy from? How do plants make their own food? What do plants need to survive and grow?
What is Photosynthesis?
The process plants use to make their own food Converts light energy into chemical energy Happens mainly in the leaves of plants Essential for all life on Earth
Photosynthesis Equation
{"left":"REACTANTS (What Goes In)\nSunlight (light energy)\nCarbon dioxide (CO₂)\nWater (H₂O)","right":"PRODUCTS (What Comes Out)\nGlucose (C₆H₁₂O₆) - plant food\nOxygen (O₂) - we breathe this!"}
The Photosynthesis Process
Hands-On: Build Photosynthesis!
Work in groups of 4-5 students Use your model kit to build the photosynthesis process Place reactants on one side, products on the other Explain your model to another group
Success Criteria Check
I can accurately label a photosynthesis diagram I can explain how plants convert light energy to chemical energy I can name the three reactants and two products I can describe why photosynthesis is important for life
Why Does Photosynthesis Matter?
Produces oxygen that we breathe Creates food for all living things Removes carbon dioxide from the air Forms the base of all food chains Next: We'll explore how energy flows through ecosystems!
