Science – Key Stage 1

• Plants: Describe and compare the structure of a variety of common plants (including trees) (Year 1 Programme of Study)
• Working Scientifically: Ask simple questions and recognise that they can be answered in different ways. Use observations and ideas to suggest answers to questions.

Specific learning objectives for this lesson:

• To identify what plants need to grow and survive (water, light, temperature).
• To describe how each factor affects plant growth using simple observations and discussions.
• To develop basic skills in caring for plants and recording information using a plant care chart.

---

Learning Objectives

By the end of this lesson, pupils will:

• Know the three main needs of plants to grow: water, light, and warmth.
• Be able to say why each need is important for a plant’s health.
• Use a plant care chart to observe and record the condition of plants.
• Understand how to care for plants at home or school.

---

Resources

• Small pots with bean seeds already planted (4 per student, experimental groups for water, light, warmth)
• Water spray bottles or small watering cans
• Basic plant care chart templates (drawings and spaces for observations)
• Pictures of healthy vs unhealthy plants
• A lamp or access to natural sunlight near the classroom window
• Thermometer or temperature display (optional)
• Whiteboard and markers
• “Plant Needs” vocabulary cards (water, light, warmth)

Lesson Structure

1. Introduction (10 minutes)

• Gather the students in a circle. Show them the plant pots with young bean seedlings.
• Ask, “What do you think plants need to grow healthy and strong?” Let them guess and discuss ideas (water, light, warmth).
• Introduce the lesson title on the whiteboard: Plant Needs for Growth.
• Use vocabulary cards to introduce the three key words: water, light, temperature (warmth).
• Show pictures comparing healthy and unhealthy plants linked to these needs.

Teacher’s Tip: Use expressive facial reactions ("plants get thirsty or cold!") to engage students.

2. Exploration Activity – Plant Care Investigation (20 minutes)

• Divide the students into four groups (1 student per group, plus teacher support) each responsible for one condition:

  1. Regular watering & light (control)
  2. No water
  3. No light (place plant in a covered box or cupboard)
  4. Cooler temperature (placed near a window or cooler spot in the room)

• Explain to the students that we are helping the plants grow by caring for them correctly, or seeing what happens when they don’t get what they need.

• Hand out the simple plant care chart:

  • Sections: Plant condition, Water given (yes/no), Light received (yes/no), Temperature (warm/cold), Observations.

• Ask students to carefully water and place their pots in the assigned conditions.

• Over the week in upcoming lessons, students will observe and record plant changes.

---

3. Group Discussion and Reasoning (10 minutes)

• Bring students together after setting up the experiment.
• Discuss “Why do plants need water?” (to drink, stay alive)
• Discuss “Why is light important?” (to make food from sunlight)
• Discuss “Why do plants need warmth?” (to grow well)
• Use the whiteboard for a quick drawing: sun, water can, and thermometer icons linking to plant.

Teacher Encouragement: Ask open-ended questions:

• “What do you think will happen if a plant doesn’t get water?”
• “How do you think the plant will change if it has no light?”
• “Why can plants be cold in winter?”

---

4. Practical Care and Wrap-Up (8 minutes)

• Give the students time to water the plants in the “control” condition group.
• Model gentle care: “Let’s be kind to our plants and make sure they have what they need.”
• Ask students to mark the care chart for today’s watering and placement.
• Recap by singing a simple “Plant Care Song” to remember water, light, and warmth (teacher to prepare a tune using common nursery rhyme melodies).

Example lyrics snippet:
Plants need water every day,
Light to shine and help them sway,
Warmth to grow in sun or shade,
Happy plants are well cared for today!

---

5. Assessment and Feedback (2 minutes)

• Use quick verbal questions:
  • “Can you tell me what plants need?”
  • “What happens if a plant doesn’t get light?”
• Ask students to point to the correct Plant Needs vocabulary card when prompted.
• Check the student’s plant care charts for understanding.

---

Extension Opportunities & Home Learning

• Suggest children watch a seed growing at home and draw or photograph it.
• Encourage parents to talk with children about caring for their own houseplants or garden plants.
• Prepare a simple observation diary for home.

---

Differentiation and Inclusion Strategies

• Use visuals heavily to support vocabulary.
• For students needing extra support, encourage drawing or stick-figure observations on the chart.
• For more advanced learners, invite them to explain why plants need each factor in their own words.
• Ensure all children have hands-on experience with watering and placement.

---

Reflection (for Teacher Use after Lesson)

• Did all students engage with the inquiry and care activity?
• Were students able to correctly identify needs of plants verbally and on the care chart?
• Note any misconceptions (e.g., confusing needs of plants vs animals) to revisit in future lessons.
• Evaluate the success of the Plant Care Song as a mnemonic and adjust for next use.

This lesson combines practical gardening skills with scientific enquiry aligned closely to the Early Years Progression and National Curriculum KS1 science standards, offering Year 1 pupils a memorable, hands-on experience with the basics of plant biology.
