Cockroaches!

This week in science, we conducted experiments on cockroaches to see whether they would hiss or not. This week, we had to design an experiment and test it out. Well, you could guess, ours was about whether the roach would hiss or not. We figured that it hisses if i is scared or agitated and maybe because it wants to scare off it's enemy. We had three categories of tests; Physical, psycological and enviormental tests.
The Physical tests were when we, the testers touched the roach and pushed it a little, and maybe assulted it a little.
 The Enviornmental tests were tests in which we replayed the conditions that the roach had to face in its everyday lifestyle.
  The psycological tests were tests that we used to effect the roaches' mind. We called the roach bad and mean names to make them feel bad.(things htat should not be heard.)
The results really fit the data. We had the roach hiss when ever we touched it or physically assulted it.
When we did the enviornmental tests, the roach never hissed.
When we did dthe psycological tests, we called the roach bad names, but it never responded.


Based on the results, we can conclude that the cockroach knows about its enciornment and does not hiss because it is scared because it just knows its home enviornment. We were not sure that the roached Knew about the mean things that we said to it.
