Immune system and infection response Module 7 lesson 2

Introduction

This lesson focuses on the immune system and the infection response, through evaluating different organisms and their responses.

Each organism from plants, to humans, to animals have a different pathogen response and have different immune structures.

A pathogen can be defined as an infectious organism that can usually cause illness.

Task

All of a sudden the zoom meeting cut out and your teacher has disappeared. Silence. But you have an idea, because you are ahead of the class you decide to share your knowledge with your peers regarding immune systems and infection response. In this task you are challenged to create a mindmap of the following headings

- Plant response to infections

- Animal responses to infections

- How Australian plants respond to pathogens

-The changes to animals physical and chemical changes in cells.

- How does the humane immune system responds to pathogens.

But after sharing your mindmap that you have created, you can see that the class is still confused so you go into more depth

Process

1. Create your mindmap with the following titles and create subheadings to summarise the key information (what you already know) in the mindmap, this can be used for later revision.

2. Compare how a plant and animal responds to infections with a minimum of three comparisons

3. Name a pathogen that is common for Australian native plants

4. Explain how the Australian plant responds to this pathogen. Determine if there is any way to prevent the pathogen

5. Elaborate on the characteristics of the pathogen and how toxic this pathogen is 

6. Compare the physical and chemical changes in an animal cell when fighting off a pathogen

7. Challenge question: Explain how the human immune system responds to a pathogen

Conclusion

syllabus outcomes
Bio11/12-2 Designs and evaluates investigations in order to obtain primary and secondary data and information 
Bio12-14 analyses infectious disease in terms of cause, transmission, management and the organism's response, including the human immune system
Inquiry question

How does a plant or animal respond to infection?

  • investigate the response of a named Australian plant to a named pathogen through practical and/or secondary-sourced investigation, for example:

  • fungal pathogens

  • viral pathogens

  • analyse responses to the presence of pathogens by assessing the physical and chemical changes that occur in the host animal's cells and tissue

Diversification: Challenge question is aimed to challenge higher achieving students. While also creative engaging lessons like mindmaps to allow students to recognise the work that they already know and build upon the existing knowledge.
