Understand how several groups of cells in our immune system work together to fight pathogens.
Develop a model that demonstrates the function of antibodies and memory cells during a primary and secondary immune response.
Explain how memory cells accelerate an immune response using experimental evidence.
What happens when you get food poisoning or the flu? How does our body fight an infection when we get sick? In this lesson, students will build a model of our immune system to find out how our body responds to invading bacteria or viruses that cause diseases and to investigate the role of memory cells.
MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
This lesson focuses on these aspects of NGSS Three Dimensional Learning:
Science & Engineering Practices
Disciplinary Core Ideas
Developing and Using Models.
Develop and use a model to describe phenomena.
Engaging in Argument from Evidence.
Use an oral and written argument supported by evidence to support or refute an explanation or a model for a phenomenon.
LS1.A: Structure and Function.
In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions.
Systems and System Models.
Systems may interact with other systems; they may have sub-systems and be a part of larger complex systems.
Models are limited in that they only represent certain aspects of the system under study.
Cause and Effect: Mechanism and Prediction.
Cause and effect relationships may be used to predict phenomena in natural or designed systems.
