Water Transport

Overview

This 50-minute lesson is lesson 12 of the unit "Seasons and Living Things" for Year 1 students (ages 5-6). The focus is on understanding how water moves through plants, linking to the National Curriculum for Science in England, particularly the Year 1 programme of study for Plants. Students will engage in a simple, hands-on experiment to observe water movement from roots to leaves.

National Curriculum Links

Primary Science: Year 1 - Plants

• Pupils should be taught to:

  • Identify and name a variety of common wild and garden plants, including deciduous and evergreen trees.
  • Identify and describe the basic structure of a variety of common flowering plants, including roots, stem/trunk, leaves and flowers.

• Working scientifically (Year 1)

  • Asking simple questions and recognising that they can be answered in different ways.
  • Performing simple tests.
  • Observing closely, using simple equipment.
  • Using their observations and ideas to suggest answers to questions.

---

Learning Objectives

By the end of the session, all pupils will be able to:

• Understand and describe that water travels from the roots up the stem to the leaves.
• Conduct a simple experiment to observe water moving through a plant.
• Use simple scientific vocabulary: roots, stem, leaves, water transport.
• Make observations and record findings using drawings and simple sentences.

Resources

• White carnations or celery stalks with leaves (1 per student)
• Clear plastic cups or jars
• Cold water mixed with food colouring (red or blue are ideal)
• Paper towels
• Large sheet of paper or whiteboard for group observations
• Drawing and writing materials (pencils, crayons)

Lesson Structure (50 mins)

1. Introduction & Recap (10 mins)

• Gather the students in a circle. Show a potted plant or a real plant if available. Ask:
  "Where do you think plants get water from?"
• Recap previous learning on plant parts, focusing on roots, stem, and leaves. Use simple drawings on the board to remind.
• Introduce today's question:
  "How does water move inside a plant?"

2. Engage - Predict and Discuss (5 mins)

• Show the students a white carnation or celery stalk and a cup of coloured water.
• Ask: "What do you think will happen if we put the plant in the coloured water?"
• Encourage predictions and record them on the board.

3. Main Activity - Experiment (20 mins)

• Give each student a clear cup containing coloured water and one carnation or celery stalk.
• Explain: "We are going to see how water travels inside the plant."
• Guide students to place the stems carefully in the water.
• Ask them to observe carefully over the next 20 minutes as they continue with the lesson or have a quiet activity nearby.
• While waiting, read a short story or poem about plants and water to reinforce the concept.

4. Observation & Recording (10 mins)

• Gather students around their plants. Prompt them:
  "Can you see the colour appearing in the leaves or petals? What do you notice?"
• Model drawing and writing a simple sentence about what they see (e.g., "The water moves up the stem").
• Pupils draw their own observations and attempt to write a sentence or label parts of the plant.

5. Plenary and Review (5 mins)

• Discuss as a group:
  • "Where did the water start?"
  • "Where did the water go?"
  • "Why do you think water travelling inside plants is important?"
• Link to seasons and how plants need water to grow and stay alive.

Assessment

• Formative assessment during questioning and discussion to check understanding of water movement and plant parts.
• Observation of pupil drawings and verbal feedback on what they noticed in the experiment.
• Simple written sentences or labels will demonstrate use of scientific vocabulary.

---

Differentiation

• Support: Pupils who need help with drawing or writing can verbally explain their observations to the teacher or peers.
• Challenge: Pupils who grasp the concept quickly can explore additional questions such as "What happens if the water is not coloured?" or "What other liquids might travel inside a plant?"

---

Extension Ideas

• Repeat the experiment but change variables: use different coloured water or different plants to see if results vary.
• Use magnifying glasses to observe the stem and leaves before and after the experiment.
• Introduce simple diagrams of the water cycle linking water intake by plants to evaporation and rain.

---

Teacher Tips

• Prepare the coloured water in advance. Priming the experiment with vibrant colours like red or blue greatly helps pupils visually track water movement.
• Use simple, clear language and lots of repetition of key vocabulary: roots, stem, leaves, water.
• Make the hands-on experience central to learning, as tactile and visual inputs support Year 1 learners best.

This lesson plan supports scientific enquiry and observation skills on an age-appropriate level, while tightly aligning with the National Curriculum aims for plants and working scientifically in Year 1. The colourful, visual experiment provides a memorable way to understand a key biological process.
