Student lesson

The lesson in 60 seconds

  1. Plants need water.
  2. Plants need light.
  3. Plants need air and soil.
  4. We can find out by looking carefully and recording.

Words to know

soil
the ground that plants grow in
water
what plants take in through their roots
air
the gas around us that plants and animals need
investigation
a way of finding out an answer by looking carefully

1. Discover: The two plants

Two bean plants stand on a windowsill. Yaw waters one every day. He forgets the other. After a week, the plant with no water is dry and bent. The watered plant is green and tall. “The dry plant needed water,” he says.

Think: What was different about the two plants?

2. Understand: What plants need

Idea 1: Plants need water

Plants take in water through their roots. Without water, they become dry and bend over. Too much water can also harm a plant.

Idea 2: Plants need light, air and soil

Leaves catch light from the Sun. Plants also take in air. Most plants grow in soil. Soil holds roots and has things that plants need.

Idea 3: An investigation

An investigation helps us find an answer. We can grow beans in a clear container with damp tissue. We look each day, draw what we see and measure how it changes.

Remember: Plants need water, light, air and soil. We can find out by looking carefully and recording.

3. Worked examples

Example 1 (I show you): What did the plant need?

A plant has no water for a week.

  1. What happened? It dried and bent.
  2. What was missing? Water.
  3. What should we do? Give it a little water.

Answer: The plant needed water.

Example 2 (We do it together): Set up a bean test

A clear cup, damp tissue, a bean seed.

  1. Put damp tissue in the cup.
  2. Place a bean between the glass and the tissue.
  3. Put it in a bright place and look each day.

Answer: We can see the bean root and shoot grow in a clear cup.

Example 3 (You try): Record the change

A bean has grown a root after three days.

Show the steps and answer
  1. Draw the bean on Day 1.
  2. Draw the root on Day 3.
  3. Write one sentence about the change.

Answer: On Day 3 the bean had a root. It grew because it had water.

Did you know?

Some desert plants can store water in their thick stems for many months.

Why this matters

Knowing what plants need helps us grow food and look after trees, gardens and flowers.

4. Explore: Bean in a cup

Set up a clear cup with damp tissue and a bean seed. Look every day for a week or more.

  1. Put damp tissue in a clear cup or jar.
  2. An adult helps you place a bean seed between the cup and the tissue.
  3. Put the cup in a bright place. Keep the tissue damp.
  4. Draw the bean every day. Write what changed.
Think about it: what did you notice?

What changed? The bean grew a root and then a shoot. It needed water and light.

Safety first: Do not eat the seeds or the tissue. Use a plastic cup, not glass. Wash your hands after touching soil, seeds or tissue.

Mastery and remediation

Objective Bronze (Developing) Silver (Proficient) Gold (Advanced)
O1 Name what plants need to grow 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 happens when a plant has no water or no light 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 Set up a simple bean investigation 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
O4 Record changes by drawing and counting 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

  1. Find the misconception: “Plants eat from the soil like people eat.” Plants take in water through roots and make their own food with light.
  2. Explain another way: use real objects, pictures or actions first, then words.
  3. Show a simpler example: Name water, light, air and soil. Say which one the bean cup shows.
  4. Guided practice: work through one example together and let the learner try the next one.
  5. Reassess: use the quiz again or the worksheet.
  6. Move on when the learner shows Silver-level evidence independently.

For parents and guardians

In this lesson your child learns what plants need to grow and starts a simple bean investigation. You do not need to be an expert to help.

  • Set up a bean cup at home.
  • Ask, “What do you notice today?”
  • Help keep the tissue damp, but not soaking.
  • 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 what plants need to grow; say what happens when a plant has no water or no light; set up a simple bean investigation; record changes by drawing and counting.

Prerequisite knowledge. None. Learners should be able to look, listen and talk about what they notice.

Materials. Clear plastic cups, tissue paper, bean seeds, water, pencils, crayons and chart paper. 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. Soak the beans for a night. Prepare one cup as an example. Make a record sheet with Day 1 to Day 7.

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 two plants, one watered and one not, and ask, “What is different?”

Explanation (10 min). Teach what plants need.

Guided activity (10 min). Set up the bean cups and draw Day 1.

Independent activity (10 min). Look every day, draw and share findings.

Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.

Key questions. What do plants need? What changed today?

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. “Plants eat from the soil like people eat.” Plants take in water through roots and make their own food with light.

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 water, light, air and soil. Say which one the bean cup shows. 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.
