Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

National Curriculum Alignment

This lesson aligns with the Australian Curriculum: Science, specifically focusing on Biological Sciences (ACSSU112) and Earth and Space Sciences (ACSSU117).

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Ecosystems	5 mins	Briefly introduce the concept of ecosystems and their importance in nature.
2	Types of Ecosystems	10 mins	Discuss different types of ecosystems using a PowerPoint presentation and videos (e.g., forest, desert, aquatic).
3	Components of Ecosystems	5 mins	Define and explain producers, consumers, and decomposers through a whiteboard diagram.
4	Group Activity	7 mins	Divide students into small groups and assign each group a local ecosystem to explore. They discuss the organisms and roles within that ecosystem.
5	Class Discussion	3 mins	Have each group share their findings briefly without formal presentations.
6	Wrap-Up and Homework Assignment	0 mins	Summarize key points of the lesson and assign homework: students create a diagram of an ecosystem of their choice and write a short description of its components. Students check each other's homework without presentations.

Homework Assignment

Students will create a diagram of an ecosystem of their choice and write a short description of its components (producers, consumers, decomposers, and relationships). This work will be peer-checked in pairs during the next lesson, ensuring all homework is reviewed without formal presentations.
