Growth Needs Exploration

Lesson Overview

In this 45-minute lesson, Year 2 students will investigate the essential needs of plants—water, sunlight, and soil—by engaging in a hands-on experiment. Pupils will observe and record how different conditions affect plant growth. This lesson supports pupils to develop their understanding of living things and their needs, aligned with the National Curriculum for Science in England, specifically the programme of study for Year 2.

National Curriculum Links

Subject: Science Year group: 2 Relevant Programmes of Study:

• Plants: Observe and describe how seeds and bulbs grow into mature plants
• Find out and describe how plants need water, light and a suitable temperature to grow and stay healthy

Key Stage 1 Science Attainment Targets:

• Pupils should be taught to:
• Identify and describe the basic structure of a variety of common flowering plants, including roots, stem/trunk, leaves, and flowers
• Observe and describe how seeds and bulbs grow into mature plants
• Find out and describe how plants need water, light and a suitable temperature to grow and stay healthy

Learning Objectives

By the end of this lesson, pupils will be able to:

• Identify and explain the importance of water, sunlight, and soil for plant growth
• Conduct a simple experiment to observe the impact of varying environmental factors on plants
• Record observations using photos and written notes
• Develop basic investigative skills by asking questions and making predictions

Resources Needed

• Ten small pots or containers (one per student or pair if sharing)
• Quick-growing seeds (e.g., cress or beans)
• Different soil types (e.g., normal garden soil, sandy soil, no soil)
• Water spray bottles or cups for watering
• Access to a sunny windowsill or artificial light source
• Clipboards with worksheets for notes
• Digital cameras or tablets (1 for each pair) for taking photos
• Chart or whiteboard for group discussion

Lesson Breakdown

1. Introduction (10 minutes)

• Engage pupils with a question: "What do plants need to grow?" Record pupils’ prior ideas on the whiteboard.
• Briefly explain using simple language that all plants need certain things to grow well: water, sunlight, and soil.
• Introduce the experiment: "Today we will see what happens when we change the amount of water, sunlight, or soil."
• Outline the experiment parameters and explain the roles for each student.

2. Setting Up the Experiment (15 minutes)

• Divide the students into three groups, each focusing on one growth factor:
• Group 1: Water (some plants get water, some do not)
• Group 2: Sunlight (some plants placed in sunlight, others in shade)
• Group 3: Soil (plants grown in different soil types or no soil)
• Each student/pair plants their seeds in pots prepared for their group's condition.
• Demonstrate how to water and place the pots accordingly.
• Students take an initial photo of their setup using digital cameras/tablets.
• Explain how to fill in the worksheet to describe their setup and initial predictions.

3. Observation and Recording (10 minutes)

• Ask pupils to observe their plants carefully.
• Guide them to make initial notes about the condition of the seeds/plants.
• Encourage use of descriptive language: size, colour, dryness, etc.
• Pupils take close-up photos of the plants to document starting points.
• Facilitate a short discussion comparing the plants’ conditions for each growth factor.

4. Reflection and Discussion (8 minutes)

• Invite groups to share their predictions and initial observations.
• Discuss the importance of water, light, and soil based on the set-up so far.
• Link observations to prior knowledge about plant needs.
• Emphasise that the real differences will be more visible over time, leading to further experiments in upcoming lessons.

5. Plenary and Next Steps (2 minutes)

• Recap what plants need to grow and survive.
• Explain that the class will monitor the plants over the next lessons, taking more photos and notes.
• Set a simple home challenge: "Can you spot any plants at home or outside and think about what they need to grow well?"

Assessment Opportunities

• Monitor contributions during group discussions to assess understanding of plant needs.
• Review pupils’ worksheets for accurate and relevant observations and predictions.
• Check photos to confirm accurate recording of experimental conditions.
• Ask open-ended questions during reflection to assess scientific thinking and vocabulary use.

Differentiation and Inclusion

• Support pupils who need help with writing by offering scribing assistance or allowing them to record oral observations.
• Provide vocabulary cards with terms like water, sunlight, soil, roots, seed, grow for EAL learners and those needing language support.
• Use paired or small-group working to encourage collaboration and peer support.
• Adjust the complexity of questions asked depending on abilities.

Cross-Curricular Links

• ICT: Use of digital cameras/tablets supports early use of technology for documentation.
• English: Developing note-taking, speaking and listening skills through scientific discussion.
• PSHE: Taking responsibility for caring for living things.

By integrating hands-on scientific inquiry with digital documentation and reflective discussion, this lesson supports deep understanding of plant growth needs while developing investigative skills appropriate for Year 2 pupils per the National Curriculum expectations.
