Module 1:
Introduction to Antigens/Self and non-self recognition
This module is an introduction to key concepts of immunity and the associated scientific nomenclature that comes with this difficult topic. Learning about the ABO blood groups will provide insight into the scientific application of the antigenic response. This module is expected to take up 1-2 hours of class time.
Summary
VCE Biology(2017-2021)
Unit 3, Area of Study 2, Outcome 2, VCE Biology Study Design
Key knowledge:
Responding to antigens
- an antigen as a unique molecule or part of a molecule that initiates an immune response including the distinction between non-self antigens, self-antigens and allergens
Duration
1-2 hours
Student learning outcomes
Upon completion of this module students will:
- state and explain the definitions of antigens and allergens
- describe and explain of the ABO blood groups in terms of antigens and antibodies
- explain the benefits and technical issues confronting scientists in the formulation of artificial blood for transfusion

Case study/practical
Determining an unknown blood group
In this experiment, simple liquids that mimic blood are used to demonstrate blood typing.
Discussion points
These questions could be used as a basis for a research project, scientific poster or just to promote scientific thinking.
- What is the importance of blood grouping?
- What other laboratory testing needs to be performed prior to transplantation?
- Why are scientists interested in creating blood?
- For artificial or synthetic blood to be successful what properties should it have?
- Why has there been many setbacks with creating blood?
