Photosynthesis
Explain photosynthesis as the process by which plants use light energy to convert carbon dioxide and water into glucose and oxygen, and describe how mineral nutrients are absorbed through roots
Lesson
Set out your lesson
“Photosynthesis means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.”
Bring to the table
- A battery, bulb, and wires OR a warm/cool cup comparison setup
- Paper for a simple energy-path note
Extra for the adult
Worked example. Battery → wires → bulb: chemical energy becomes light (and some heat).
Optional challenge. For Photosynthesis, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Photosynthesis, not mastery.

Photosynthesis means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.
Materials: A battery, bulb, and wires OR a warm/cool cup comparison setup; Paper for a simple energy-path note. 1. Say the goal of Photosynthesis in plain words once. 2. Adult shows one energy transfer (circuit lights, or heat moving to a cooler hand nearby) and names the path. 3. Child traces or describes three energy paths and says what changed. 4. Fresh check: one fresh energy-path description. Record and stop. Done: three energy-path notes with a before/after change. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

Check understanding
- Writes and explains the word equation for photosynthesis
- Identifies the raw materials needed and the products made
- Explains the role of chlorophyll in capturing light energy
- Distinguishes between what plants get from the air (CO₂), soil (water and minerals), and light
“If your child was asked why plants don't need to eat food like animals do, could they explain how plants make their own food using sunlight, water, and carbon dioxide — and write the equation?”
