Lesson notes

Learning Objectives

Indicator: B6.3.3.1.1

By the end of the lesson, learners can:

Identify at least three different types of interactions (predation, competition, and mutualism) that occur within an ecosystem.
Observe an outdoor ecosystem and record at least two examples of living things interacting with each other.
Explain how human activities such as hunting, farming, and pollution affect the balance of an ecosystem.
Design a simple diagram of an ecosystem showing at least three interactions among the organisms present.
Discuss how changes in one part of an ecosystem can affect humans and other living things.

Exemplars (from the NaCCA curriculum)

- Show learners pictures of different ecosystems.
- Learners observe different ecosystems in the field such as a small bush or pond.
- Engage learners to brainstorm to come out with possible interactions that occur in the given ecosystem.
- Learners work in groups to draw or design different ecosystems in the classroom.
- Learners observe each of the ecosystems and identify some possible interactions that can take place within each ecosystem they have designed.
- Guide learners to discuss the effects of interactions (hunting, farming and predation) on humans and other living things within a given ecosystem.
