Exploring Our Environment

Overview

This 60-minute lesson introduces Year 5 students to fundamental concepts of the environment, focusing on ecosystems, habitats, and biodiversity. The lesson aligns with the National Curriculum for England's Science Programme of Study for Key Stage 2 (Years 3-6), specifically addressing objectives related to living things and their habitats.

National Curriculum Links

• Science Programme of Study: Living things and their habitats (Key Stage 2)
  • Describe the differences in the life cycles of a mammal, an amphibian, an insect and a bird. (Relevant in understanding ecosystems)
  • Describe the life process of reproduction in some plants and animals.
  • Recognise that environments can change and that this can sometimes pose dangers to living things.
  • Describe how living things are classified into broad groups according to common observable characteristics and based on similarities and differences.
  • Describe the concept of a habitat as the natural environment in which an organism lives.
  • Understand the interdependence within an ecosystem including common environmental changes and their effects on biodiversity

Learning Objectives

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

1. Define what an environment is and explain its importance.
2. Describe what an ecosystem and habitat are, including examples.
3. Understand the concept of biodiversity and why it matters.
4. Create a simple self-sustaining ecosystem (terrarium) and predict how living and non-living components interact.
5. Conduct a short quiz to assess their understanding of key terms and concepts.
6. Prepare for a homework task researching local biodiversity to deepen learning.

Lesson Structure

1. Introduction & Class Discussion (10 minutes)

• Starter Question: Write on the board: “What is the environment?”
• Invite students to share ideas and write keywords on the board. Aim to capture ideas about air, water, land, plants, and animals.
• Show pictures of different environments (e.g., forest, pond, city park) and discuss how each supports different living things.
• Clarify the definition: The environment is everything around us that affects living things, including plants, animals, air, water, and soil.

National Curriculum connection: Understanding environments and how they provide habitats for living things.

2. Introducing Key Concepts: Ecosystems, Habitats, Biodiversity (15 minutes)

• Define and explain:
  • Ecosystem: A community of living things interacting with each other and their non-living surroundings.
  • Habitat: The natural home or environment of an animal, plant, or other organism.
  • Biodiversity: The variety of different living things in an area.
• Use visual aids illustrating ecosystems (woodland, pond, meadow), pointing out habitats and examples of organisms living there.
• Highlight the importance of biodiversity for ecosystem health and resilience.
• Distribute vocabulary cards and have students match words with their definitions in pairs.

National Curriculum connection: Describing habitats and understanding interdependence in ecosystems.

3. Experiment: Creating a Mini Ecosystem (Terrarium) (20 minutes)

• Divide students into groups of 4-5. Each group receives a jar/container and materials (soil, stones, plants, water).
• Guide them step-by-step:
  1. Add small stones at the bottom for drainage.
  2. Add a thin layer of activated charcoal (to prevent odours and bacteria).
  3. Add soil.
  4. Plant moss or small plants.
  5. Lightly spray water.
  6. Place a loose-fitting lid or cover (not airtight) to allow some air exchange.
• Discuss how this jar represents an ecosystem: plants will produce oxygen, soil and stones provide structure, moisture cycles inside, microorganisms sustain the environment.
• Challenge groups to predict what might happen over time if left in sunlight.

National Curriculum connection: Recognising how environments can be self-sustaining and the interaction of living things within habitats.

4. Plenary: Quiz and Reflection (10 minutes)

• Distribute a short quiz with 5 multiple-choice or short-answer questions on:
  1. What is an environment?
  2. Define ecosystem and habitat.
  3. Give an example of a habitat.
  4. Why is biodiversity important?
  5. What living and non-living things did you use in your terrarium?
• Review answers as a class, reinforcing correct understanding and clarifying misconceptions.
• Ask students how they think their terrarium represents an ecosystem and what might happen if it changes.

---

5. Homework Assignment (to be completed by next lesson)

• Research Task: Investigate local biodiversity by identifying three different plants or animals found in the local area (garden, park, school grounds).
• Prepare a short presentation or a poster with pictures/drawings and a few interesting facts about each organism.
• Encourage students to think about the habitats and ecosystems these organisms live in.

National Curriculum connection: Developing research and presentation skills alongside science knowledge.

---

Assessment Summary

• Ongoing formative assessment during discussion and group activity.
• End-of-lesson quiz to check understanding of key terms and concepts.
• Homework research presentation to assess ability to apply knowledge of biodiversity and habitats independently.

---

Differentiation and Inclusion

• Provide vocabulary cards with pictures for EAL learners and students with special education needs.
• Groups with mixed ability to support peer-assisted learning during the experiment.
• Support with sentence starters for quiz and homework presentation.
• Use visual and tactile resources to engage learners with different learning styles.

---

Reflection & Extension Ideas

• Extension: Plan a visit to a local nature reserve or garden to explore real-life ecosystems.
• Invite a guest speaker such as a local ecologist to discuss British biodiversity.
• Set up a classroom biodiversity chart to record local wildlife sightings throughout the year.

This immersive, practical lesson encourages active learning through discussion, hands-on experience, and creative expression, fully meeting the requirements of the UK National Curriculum for Year 5 Science.
