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.

This week, we went on a field trip. This is five scientific things i learnt on the trip;
1)the mud in a bog is full of tanning acides that when a man was thrown into the bog, then picked up 1000 years later, th ebody was fully preserved but the body was tanned like leather.
2)When you are out in th ewilderness, and it is cold. You do not have any thing but sticks to build a shelter, build a shelter low to the ground. this will thake your body heat and warm the small area that you are in.
3)Salamanders breathe from their skin!
4)Cratures that live in a stream have a stronger body/aerodyminicle body to fight the current of the water.
5)When a stromg wind is coming,and you have a high structure, the wind could snap the structure in half. Tha tis why you should put holes in the building so the air passes through the building

this week in science

this week in science, we did many things. on Monday, we worked on my project and i had to do the smart technologies assignment. on tuesday, i handed everything in and my stress wasover. On wednesday, i had to study for the test. Then we got to play with cockroaches. They were really cute. They had little cute legs with fuzz on them. they had a hard shell and and when you tried to pick them up, they hissed like a snake at you. They are awesome!
On thursday,we had ht great science test! It was not so hard but you had to write a lot.
On friday, we finished our tests and we played with the cockroaches again.l
