📝 lesson activities
45 min total
0–5 min
warm-up: what do plants eat?
Quick think-pair-share. Students discuss what they think plants need to survive. Collect answers on board.
5–20 min
direct instruction: the photosynthesis equation
Present the equation 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂. Walk through each component with visual diagram. Emphasize energy transformation from light to chemical.
20–35 min
hands-on: build the process
Students work in pairs to create a labeled diagram showing inputs entering a leaf and outputs leaving. Materials: colored paper, scissors, glue sticks.
35–45 min
wrap-up: exit ticket
3-2-1 exit ticket: 3 things you learned, 2 things that connect to your life, 1 question you still have.
🔀 differentiation
support
Pre-made diagram template with labels for students to match. Simplified equation card. Pair with stronger partner during hands-on activity.
challenge
Research the Calvin cycle and add it to their diagram. Compare photosynthesis with cellular respiration. Write an explanation for a younger student.
📋 assessment
Formative: observe pair discussions during warm-up for prior knowledge
Formative: check diagrams for accuracy of labels and process flow
Summative: collect and review 3-2-1 exit tickets
