Understanding Photosynthesis: How Plants Make Food
Learning Objectives
- Understand the process of photosynthesis
- Identify key components
- Recognize importance
- Explain the role of chlorophyll
- Connect to food chains
- Apply knowledge to real-world examples
Lesson Plan
Segment 1: Introduction to Photosynthesis
15 minutesObjective: Introduce the concept of photosynthesis and activate prior knowledge
- Begin with a KWL chart: 'What do you know about how plants get food?'
- Show a short educational video about photosynthesis (3-5 minutes)
- Ask students: 'How do plants get their food? Do they eat like animals?'
- Discuss student responses and introduce the term 'photosynthesis'
- Display a large poster showing a plant with arrows indicating the process
Check for Understanding: Can students explain what photosynthesis is in their own words? Ask 2-3 students to share.
Segment 2: Exploring the Components - Inputs
20 minutesObjective: Identify and understand the inputs needed for photosynthesis
- Display an interactive diagram showing sunlight, water, and carbon dioxide
- Demonstrate: Place a plant in sunlight and discuss what it needs
- Students work in pairs to create flashcards for each input component
- Class discussion: 'Where does each input come from?'
- Hands-on activity: Students observe a plant and identify where it gets each input
Check for Understanding: Can students name all three key inputs and explain where they come from?
Segment 3: The Role of Chlorophyll
15 minutesObjective: Understand how chlorophyll captures light energy
- Show images of green leaves and explain chlorophyll is the green pigment
- Demonstrate with leaf samples: 'Why are leaves green?'
- Students observe different colored leaves and discuss chlorophyll content
- Create a simple model: Use green paper to represent chlorophyll capturing light
- Connect to the concept: Chlorophyll is like a solar panel for plants
Check for Understanding: Can students explain what chlorophyll is and why it's important?
Segment 4: The Process in Action - Step by Step
25 minutesObjective: Understand how photosynthesis works step-by-step and identify outputs
- Demonstrate with a simple experiment: Place a leaf in sunlight and observe
- Students create a detailed flow chart showing: Inputs → Process → Outputs
- Use manipulatives: Students arrange cards showing the process in order
- Group activity: Each group explains one step of photosynthesis to the class
- Discuss outputs: Glucose (food) and oxygen (what we breathe)
- Connect to the chemical equation: CO2 + H2O + Light → Glucose + O2 (simplified)
Check for Understanding: Can students sequence the steps of photosynthesis and identify both outputs?
Segment 5: Why Photosynthesis Matters
20 minutesObjective: Recognize the importance of photosynthesis for all life on Earth
- Brainstorm: 'What would happen if plants couldn't photosynthesize?'
- Create a concept map showing connections: Photosynthesis → Oxygen → Animals → Food chains
- Discuss real-world examples: Forests, ocean plants, food production
- Group discussion: 'How do humans depend on photosynthesis?'
- Reflection activity: Students write one reason why photosynthesis matters to them
Check for Understanding: Can students explain at least two reasons why photosynthesis is important?
Segment 6: Application and Review
15 minutesObjective: Apply knowledge and review key concepts
- Quick review game: 'Name that component' (inputs/outputs)
- Students create their own diagram of photosynthesis with labels
- Share diagrams with partners and provide feedback
- Exit ticket: 'Draw and label one thing you learned about photosynthesis'
- Preview next lesson: 'Tomorrow we'll explore how different plants use photosynthesis'
Check for Understanding: Can students create an accurate diagram showing the photosynthesis process?
Materials Needed

- Simple plant diagram worksheets
- Magnifying glasses for leaf observation
- Construction paper (green, yellow, blue) for models
- Timer or stopwatch for activities
- Exit ticket templates
Photosynthesis Practice Exercises
These exercises will help you practice and reinforce your understanding of photosynthesis through various hands-on and creative activities.
Label the Diagram
Label the parts of a plant involved in photosynthesis
Instructions: Draw a detailed plant diagram and label: leaves, roots, stem, stomata, and chloroplasts. Indicate where photosynthesis occurs and write what each part does in the process. Include arrows showing the flow of inputs and outputs.
Photosynthesis Story
Write a creative story from a plant's perspective
Instructions: Write a short story (2-3 paragraphs) from the point of view of a plant describing its day making food through photosynthesis. Include all the key components (sunlight, water, carbon dioxide, chlorophyll, glucose, oxygen) and explain how the plant feels during the process.
Compare and Contrast: Photosynthesis vs. Human Nutrition
Compare photosynthesis to how humans get energy
Instructions: Work with a partner to compare photosynthesis to how humans get energy. Create a detailed Venn diagram showing: similarities (both need energy, both produce waste), differences (plants make their own food, humans eat food; plants use sunlight, humans use food). Present your findings to the class.
Photosynthesis Experiment: Testing Light Requirements
Conduct a simple experiment to observe photosynthesis
Instructions: In groups of 3-4, set up an experiment: Place one plant in sunlight and one in darkness. Observe and record changes over 3 days. Document: leaf color, plant health, any visible changes. Create a hypothesis and conclusion about the role of light in photosynthesis.
Create a Photosynthesis Model
Build a 3D model showing the photosynthesis process
Instructions: Using craft materials, create a 3D model of a plant showing: leaves with chlorophyll (green), roots taking in water, carbon dioxide entering through stomata, sunlight hitting the leaves, and oxygen being released. Label all parts and create a key explaining each component.
