National Curriculum References

Science Programme of Study – Key Stage 1 (Years 1 and 2):

• "Identify and name a variety of common wild and garden plants, including deciduous and evergreen trees" (Year 1)
• "Observe changes across the four seasons"
• "Identify and describe the basic structure of a variety of common flowering plants, including roots, stem/trunk, leaves and flowers"
• "Pupils should use their observations and ideas to suggest answers to questions"
• Understand that living things have basic needs including air, light, water, nutrients, and space.

Learning objective derived from these:

• Working scientifically: ask simple questions and recognise that they can be answered in different ways.
• Biology: Observe closely using simple equipment; Identify and name parts of plants and understand that plants need certain conditions to grow.

---

Learning Objectives

By the end of the lesson, pupils will:

1. Recognise and name the basic needs of plants: air, light, water, nutrients, and space.
2. Understand that different plants may require these needs in different amounts or conditions.
3. Explore and suggest how a lack or excess of one of these needs affects plant growth.
4. Use observations and prior knowledge to answer questions about plant needs.
5. Begin to understand the importance of caring for plants by providing the right conditions.

Resources Needed

• Small potted plants (preferably different types, e.g., sunflower, bean plant, succulent)
• Transparent plastic cups
• Soil
• Water spray bottle
• White paper sheets (to simulate darkness)
• Labels or cards with pictures and words (Air, Light, Water, Nutrients, Space)
• Magnifying glasses
• Clipboards, pencils, and recording sheets with simple check boxes and drawing space
• Large illustrated poster showing a plant and its needs
• A small sealed container with a houseplant (to demonstrate limited air)
• Sunlight spot or lamp (for light demonstration)

---

Introduction (10 minutes)

Engage & Activate Prior Knowledge

• Sit the children in a circle with the potted plants visible.
• Start with a friendly, open question: “What do you think plants need to grow?”
• Use a brain storm: write or draw their ideas on a whiteboard or flip chart.
• Introduce the five main needs: air, light, water, nutrients, and space using illustrated cards.
• Show the large poster that labels and illustrates each plant need clearly.
• Reinforce with simple explanations – keep language clear and age-appropriate.

Main Activity (30 minutes)

Investigation Stations (20 minutes)

Set up five stations, each representing one plant need:

1. Air Station: Show the potted plant inside a sealed container versus one outside. Ask questions: “What happens if the plant can’t get air?”
2. Light Station: Cover one plant with white paper to block light and expose another to sunlight or artificial light.
3. Water Station: Spray one plant lightly with water, leave one dry; discuss how plants feel and look.
4. Nutrients Station: Use pots with nutrient-rich soil vs. plain soil.
5. Space Station: Show a crowded plant pot vs. one with enough space; demonstrate by gently pushing plants together and apart.

Students rotate in pairs (2 per station), observing carefully with magnifying glasses and recording simple notes or drawings on sheets — e.g., "This plant looks healthy" / "This plant is droopy".

Teacher Role: Prompt with guiding questions, e.g., "What do you notice about the plant that doesn’t get light?" Encourage the use of scientific vocabulary. Support students’ curiosity.

Group Discussion (10 minutes)

• Return to the circle.
• Ask each pair to share one observation from their stations.
• Discuss how the observations help us understand what plants need.
• Reinforce that different plants sometimes need different amounts of these things.
• Emphasise how we can help plants by giving them the right care.

---

Plenary (5 minutes)

• Recap: Show the five need cards again.
• Quick quiz game: Hold up a card and ask, “What happens if a plant doesn’t get this?”
• Praise student answers and gently correct misconceptions.
• Set a simple challenge for home or next lesson: “Can you spot what plants need in your garden or at home?”

---

Assessment

• Formative assessment during group discussion and investigation stations through observation of participation, accurate use of vocabulary, and recorded notes/drawings.
• Teacher questions and prompts used to check understanding.
• Informal plenary quiz to assess recall and comprehension of plant needs.

---

Differentiation and Inclusion

• Use visual aids and real plants to support language learners.
• Provide sentence starters on recording sheets for less confident writers.
• Scaffold observations with prompts for children who need extra help.
• Challenge more able learners to explain why some plants (e.g., cacti) need less water.

---

Extension Idea

• Begin a class grow-your-own plant project where each child plants seeds and tracks growth with a simple diary, applying their new knowledge of plant needs.

---

Reflection for Teacher

• Note which plant needs caused confusion.
• Adjust future lessons to include more hands-on time or sensory exploration.
• Consider incorporating technology like time-lapse videos of plant growth for visual reinforcement in future lessons.

This lesson blends direct teaching with hands-on inquiry aligned fully to the National Curriculum, ensuring young learners connect scientific knowledge with real-world experience. Its interactive nature will captivate small groups, making science tangible and exciting.
