week of 4/20/09

this week we worked on our cockroach projects!!  i was absent on monday and tuesday :( so sad i bet you all missed me.  but on wednesday my group organized our project and ideas, thursday we did the exeriment, and friday we presented our results.  our test was to see what makes a cockroach hiss?  we did physical, environmental, and pyschological tests.  we found that the cockroaches hissed only under physical tests (2/3 of the time it hissed) and it did not hiss at all under pyschological or environmental tests.
