Biology Unit 4 AOS 1 - How do organisms respond to pathogens?

This unit is composed of two different modules that can be completed individually (approximately 4 hours each). The modules include:

Biology Unit 4 AOS 1: 1.1 - Responding to antigens

Students will explore how organisms respond to different antigens through images, videos, scaffolded explanations, and guided questions for the following:

• physical, chemical and microbiota barriers

• the innate immune response

• initiation of an immune response

Biology Unit 4 AOS 1: 1.2 - Acquiring immunity

Students will explore how organisms acquire immunity through images, videos, scaffolded explanations, and guided questions for the following:

• the role of the lymphatic system in the immune response

• the characteristics and roles of the components of the adaptive immune response

• the difference between natural and artificial immunity

Biology Unit 4 AOS 1: 1.3 - Disease challenges and strategies

Students will explore different aspects of disease management through images, videos, scaffolded explanations, and guided questions for the following:

• the emergence of new pathogens and re-emergence of known pathogens

• scientific and social strategies employed to identify and control the spread of pathogens

• vaccination programs and their role in maintaining herd immunity

• the development of immunotherapy strategies
