1. Discover: The morning bucket

Esther fetches a bucket of water from the tap. Some of it she drinks, some she uses to wash her hands, some she pours on the school garden. “We use water in so many ways,” she says. “Plants and people both need it.”

Think: Who else needs water?

2. Understand: Water

Idea 1: What is water?

Water is a clear liquid with no taste or smell. It is found in rivers, lakes, seas, rain and under the ground. Over two thirds of the Earth’s surface is covered in water.

Idea 2: Three forms

Water can be a liquid, ice (solid) or steam (a gas). Water vapour is also in the air all around us.

Idea 3: Why we need it

People, animals and plants need water to live. Our bodies are mostly water. We drink, cook, wash and grow food with it.

Remember: Water is a clear liquid that can also be ice or steam. All living things need water.

3. Worked examples

Example 1 (I show you): Forms

Ice, water, steam.

  1. Ice: solid.
  2. Water: liquid.
  3. Steam: gas.

Answer: Water has three forms.

Example 2 (We do it together): Where?

Rivers and rain.

  1. Fresh water.
  2. Falls as rain.
  3. Fills rivers.

Answer: Water is found in many places.

Example 3 (You try): Need

Plants and animals.

Show the steps and answer
  1. Plants need water.
  2. Animals drink.
  3. Both need it.

Answer: All living things need water.

Did you know?

Your body is about 60 per cent water.

Why this matters

Water is essential for health, farming and industry.

4. Explore: Water hunt

List places water is found and used.

  1. Walk with an adult.
  2. List water sources.
  3. List uses.
  4. Draw a water map.
Think about it: what did you notice?

What did you notice? Water is everywhere.

Safety first: Stay away from deep water. Do not drink untreated water. Wash hands after touching water outside.

Mastery and remediation

Objective Bronze (Developing) Silver (Proficient) Gold (Advanced)
O1 Say what water is 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 Name three forms of water 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 Find water around us 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 Explain why living things need water 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: “Water is only a liquid.” It can be ice or steam.
  2. Explain another way: use real objects, pictures or actions first, then words.
  3. Show a simpler example: Explain three forms of water.
  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 water is and where it is found. You do not need to be an expert to help.

  • Talk about water in your home.
  • Ask, “Where does it come from?”
  • Draw a water map.
  • 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: say what water is; name three forms of water; find water around us; explain why living things need water.

Prerequisite knowledge. Grade 1 ideas: weather and the sky, water around us and keeping our environment clean.

Materials. Paper, pencils, pictures of water forms. 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. Gather water pictures. Prepare record sheets.

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). Pour water and ask, “Where does it come from?”

Explanation (10 min). Teach water.

Guided activity (10 min). Learners map water.

Independent activity (10 min). Learners present.

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

Key questions. What form is it? Why do we need it?

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. “Water is only a liquid.” It can be ice or steam.

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. Explain three forms of water. 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.
