Overall Program Objective To develop and test an immunology-
based educational unit designed for first and/or second year high school biology students based on my AAI summer research experience

Curriculum Overview Cruikshank Lab: T cell migration and
function during tuberculosis infection A third of the world’s population is infected
with the TB bacterium; one in 10 of them will become sick with active TB in their lifetime.
TB is responsible for a death every 20 seconds.
An estimated 490,000 new cases of TB resistant to first-line drugs and 40,000 cases of TB resistant to second-line drugs occur every year. (SciAm – March 2009)

Curriculum Overview 4 ELISA
Virtual HHMI Immunology Lab Simulated HIV/AIDS
Students will be able to describe the basics of an ELISA assay and practical uses of this type of lab assay.

Assessment Narrative Essays
You are to write a 3-4 page story in the first person (call the protagonist “I”) describing yourself as one who contracts tuberculosis, suffers from the disease and then begins a regimen of antibiotics to cure the disease.
Now, write the same story (3-4 pages) from the point of view of the germ! What do you as the causer of the disease hope to accomplish? What is your experience inside the human body? How did you get there? Was it easy or difficult? Did you mean to do it? What are your worries and concerns regarding the immune system? (Did a macrophage eat any of your friends?)
