Student lesson
Words to know
the part that grows in soil
the part that holds the plant up
the part that makes food
the part that makes seeds
1. Discover: The pulled-up weed
Esi pulls a small weed from the garden. “Look, it has white threads at the bottom, a thin green stalk and flat green leaves,” she says. Her teacher asks, “What does each part do?”
Think: Why might the plant need threads at the bottom?
2. Understand: Plant structure
Idea 1: Four main parts
Most flowering plants have roots, a stem, leaves and flowers. Each part has a job that helps the plant live.
Idea 2: Jobs of the parts
Roots hold the plant and take in water. The stem holds the plant up and carries water. Leaves make food using light. Flowers make seeds.
Idea 3: Parts work together
If one part is damaged, the whole plant can suffer. The parts work together like a team.
3. Worked examples
Example 1 (I show you): Name
Find the part in the soil.
- It is under the ground.
- It holds the plant.
- It is the root.
Answer: Roots grow in soil.
Example 2 (We do it together): Job
What do leaves do?
- They are flat and green.
- They catch light.
- They make food.
Answer: Leaves make food for the plant.
Example 3 (You try): Draw
Draw a plant.
Show the steps and answer
- Draw roots.
- Draw stem and leaves.
- Label each part.
Answer: Labels show we know each part.
Did you know?
Some plants, like cacti, have thick stems that store water so they can live in dry places.
Why this matters
Knowing plant parts helps us grow and care for plants and crops.
4. Explore: Label a plant
Study a real plant and label it.
- Look at the plant carefully.
- Draw it.
- Label roots, stem, leaves, flower.
- Write one job for each part.
Think about it: what did you notice?
What did you notice? Every part looked different and had a different job.
5. Practise

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Name the main parts of a plant | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O2 Say what each part does | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O3 Draw and label a plant | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “Only leaves are important.” All parts matter.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Name plant parts and say what each does.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child learns the main parts of a plant and their jobs. You do not need to be an expert to help.
- Look at a plant together.
- Ask, “Which part is this?”
- Do not taste unknown plants.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: name the main parts of a plant; say what each part does; draw and label a plant; compare plants.
Prerequisite knowledge. Grade 2 plant ideas: the parts of a plant, what seeds need to grow, and the plant life cycle.
Materials. Small plants, hand lenses, paper, pencils, gloves. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Choose safe plants. Provide gloves.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Show a plant and ask, “What can you see?”
Explanation (10 min). Teach the four parts.
Guided activity (10 min). Learners draw and label.
Independent activity (10 min). Share jobs of each part.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What does each part do?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “Only leaves are important.” All parts matter.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Name plant parts and say what each does. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
