You are an epidemiologist charged with investigating and putting a stop to repeated outbreaks of giardiasis in an old, run-down, urban public school. Discuss the hypotheses you would form and the investigation that you would undertake.

Most likely you'd look for contamination of the water sources in the school, since that's where giardia infections originate.
Hypothesis: Some source of water in the school is contaminated with Giardia.
Investigation: take water samples from every possible source in the school and have it tested for giardia.

Well, you'd probably start by investigating the problem at hand -- giardiasis. You'll want to research what it is, what it does, what part of the body it affects, and how it's transmitted. (just a quick google search)
Then you'd hypothesise why you think it is being so frequently transmitted in this particular school.
Then you're going to want to find a way to investigate from there. You might investigate something in the school, test the students for something, and so on.
Good luck. ^^
