Activity Introduction

Quick summary: Students demonstrate their prior learning about biodiversity by contributing to a mural. They will create different elements that can be be found in an ecosystem and place them in the mural.

Learning goals:

• Students use prior knowledge to contribute to a mural the kinds of plants and animals that live in several ecosystems.
• Students will scale their images so they reflect size differences in the mural.

Introduction

Students are familiar with several ecosystems. Keep the mural throughout the unit of work. As students learn more, they can add further elements to the mural. It is best if the mural is not filled up immediately.

The images students draw for the mural need to reflect something about the relative size difference. For example, a fly should be a lot smaller than a kangaroo.

Create a mural

Provide a large area on a wall covered with paper. Divide the paper into four areas: the sea, a pond an area for a forest and an area for grassland.

Explain to students they will create a mural of a forest, grassland, pond and the sea. Don’t provide too many ideas at this stage. Students can’t intrude onto other ecosystems.

Divide the class into four groups, one for each ecosystem. Students are to:

1. Draw/paint illustrations that can be pasted onto the mural.

2. Draw/paint any physical things that might be in that environment.

3. Draw/paint the plants. Students will need to have

Student Worksheet

You are going to be working in groups to create a mural of an ecosystem, such as a forest, grassland, pond or the sea.

In a small group, you will be given an ecosystems and your job is to create a drawing or painting that can be pasted onto the class mural. You need to think about the living and non-living things that might be in your ecosystem. When you draw animals their size must reflect the size of the plants and the size of the other animals.
