Biodiversity Collage Creation

Overview

In this engaging 45-minute lesson, 3rd-grade students will visualise and express their understanding of local ecosystems by creating a biodiversity collage. By integrating art and science, students will represent various plants and animals native to British Columbia, demonstrating their comprehension of biodiversity and habitats. This lesson is the fifth in an eight-lesson unit titled Exploring Local Ecosystems.

Curriculum Connections

British Columbia's Curriculum (Science - Grade 3):

• Big Idea: Living things are diverse, can be grouped, and interact in their ecosystems.
• Curricular Competencies:
  • Communicate ideas, findings, and solutions to problems (e.g., through drawing and other representations).
  • Demonstrate curiosity and a sense of wonder about the world.
• Content:
  • Local ecosystems and biodiversity
  • Basic needs of plants and animals
  • Patterns in the natural world
• Personal and Social Competency:
  • Collaboration and respect for diverse ideas during group work.

Learning Objectives

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

• Identify and represent a variety of local plants and animals found in British Columbia ecosystems.
• Explain the concept of biodiversity and why diverse species are important for a healthy ecosystem.
• Collaborate respectfully with peers to create a group collage that reflects shared learning.
• Communicate their understanding of local ecosystems through an artistic medium.

Materials Needed

• Large poster boards or cardboard sheets (one per group)
• Variety of magazines, printed images of BC flora and fauna, coloured paper
• Scissors, glue sticks, tape
• Markers, crayons, coloured pencils
• Sticky notes for labelling
• Whiteboard and markers
• Optional: digital projector to display local ecosystem images

Lesson Outline

1. Introduction (5 minutes)

• Begin with a brief whole-class discussion:
  • Recap the previous lessons on local ecosystems and biodiversity.
  • Ask students: "What kinds of plants and animals live in our local area?"
• Introduce today's creative challenge: "Today we will create a colourful collage that shows the amazing diversity of living things in our local ecosystems."

2. Mini-lesson and Modelling (7 minutes)

• Display images or use digital projector to show examples of local BC plants and animals (e.g., Douglas fir, western red cedar, black bear, Douglas squirrel, Pacific salmon, bald eagle, ferns).
• Introduce the term biodiversity: the variety of different kinds of living things in one place.
• Model how to select pictures/images and arrange them thoughtfully on the collage board for balance and meaning.
• Emphasise including a variety of species from different groups (plants, mammals, birds, insects).

3. Group Work: Creating the Collage (25 minutes)

• Divide class into 4 groups of 5 students.
• Each group receives one poster board and access to art supplies and images.
• Students collaboratively select images and design their biodiversity collage.
• Encourage students to discuss which species to include and why they matter to the ecosystem.
• As students work, circulate and ask guiding questions:
  • "How do these plants and animals depend on each other?"
  • "Can you find an animal and a plant that live close to each other in our area?"
  • "Why is it important to have many different kinds of living things here?"
• Students use sticky notes to label key plants and animals on their collage (e.g., "Pacific salmon - helps feed bears and eagles").

4. Sharing and Reflection (7 minutes)

• Each group briefly presents their collage to the class, highlighting a few included species and why they are important.
• Prompt students to reflect:
  • "What did you learn about the variety of life in our local ecosystem?"
  • "Why is biodiversity important?"
• Record some student responses on the board as a collective summary.

5. Conclusion and Clean-up (1 minute)

• Reinforce the idea that biodiversity keeps ecosystems healthy and resilient.
• Remind students to help take care of local plants and animals in their community.
• Students tidy work areas and store collages for display.

Assessment

• Formative: Observe group collaboration and engagement during collage creation, noting students’ ability to select relevant local species and explain their choices.
• Summative: Use a simple checklist evaluating:
  • Inclusion of at least 5 different plants and animals native to British Columbia.
  • Accurate use of labels and a variety of species types.
  • Clear communication during group presentation about biodiversity concepts.

Differentiation and Extensions

• For diverse learners:
  • Provide pre-cut images or simplify choices for students needing support with cutting or selection.
  • Pair English Language Learners with bilingual peers and use visual vocabulary cards for plant and animal names.
• Extension:
  • Invite students to add facts they remember about each organism around their collage.
  • Encourage students to write a short “life story” for one plant or animal on a separate sheet, connecting to personal experience or family culture.

Teacher Reflection

• Were students able to connect their artistic representation to real-world biodiversity concepts?
• Did the collaborative activity foster a respectful and inquisitive learning environment?
• How might technology (e.g., tablets for digital collage) or outdoor components be integrated in subsequent lessons to deepen understanding?
