Learning Objectives

• Define key plant chemistry vocabulary including photosynthesis, chlorophyll, carbon dioxide, and glucose.
• Explain how plants use water, carbon dioxide, and sunlight to produce glucose and oxygen.
• Identify the role of leaves and chloroplasts in the plant’s chemical processes.
• Interpret simple diagrams and data related to photosynthesis and gas exchange.
• Demonstrate understanding through independent practice and a short assessment.

Materials Needed

• Student handout with reading passage and independent practice questions
• Plant/photosynthesis diagram
• Pencil
• Highlighters or colored pencils
• Exit ticket or short quiz
• Whiteboard and markers

Support

• Provide a partially labeled diagram for students who need extra support.
• Offer a word bank with definitions and sentence frames for written responses.
• Allow students to reread the passage and use highlighters to mark key ideas.
• Pair visual cues with vocabulary cards for English learners.
• Chunk the practice into smaller sections and check in after each section.

Challenge

• Ask advanced students to explain how photosynthesis is connected to cellular respiration.
• Have students write a claim-evidence-reasoning response about why sunlight is essential to plant survival.
• Include an extension question about what happens to plant growth if carbon dioxide is limited.

Checks for Understanding

• Collect warm-up responses to gauge prior knowledge.
• Observe annotations during reading for correct identification of inputs and outputs.
• Circulate during practice to check for accurate use of vocabulary.
• Use the quiz or exit ticket to confirm understanding of the photosynthesis process.

Closure

Review the correct photosynthesis equation and ask students to name one input, one output, and one plant structure involved in the process. Reinforce that plants use chemistry to make food and support life on Earth.
