Students will develop a pathogen
based upon their knowledge of pathogens (1 day).
After presenting it to the class, the class will
then suggest ways that the pathogen might be combated
(1-2 days). In response to the classes of defenses
the immune system has, students will then show how
possible changes in structure or modification can
be useful adaptations for the pathogen (1 day).
1. Drawing upon the different bugs you have met over
the past few days design a pathogen. You can draw
upon some of the qualities of pathogens you have
encountered. Do not copy an existing pathogen. Address
the following issues:
1) Name your pathogen.
2) What is your cell type? Pathogen type?
3) How do you invade your host?
4) How does your host try to defend against you?
5) How do you evade host defense?
6) Describe your life cycle.
2. Present your pathogen to the class. The rest
of the class will play the role of the immune
system you are testing against. They will try
the host you choose with their knowledge
of the immune system and how pathogen/host
are given for use of the immune system
knowledge used to combat your pathogen. Each
a secretary to take notes on what they feel are
that will be addressed in the evolution
section. The teacher will assess points for
and appropriateness of “defense”.
3. Redesign your pathogen based on the
defenses (of your classmates!) you encountered.
make each modification to your pathogen.
students answer the questions in developing their model
pathogen? Within a class discussion are they able to
identify aspects of the immune system that defend against
specific types of pathogens? Can students recognize possible
physical or behavioral changes that would have an evolutionary
