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

Genetic Variety in Reebops

When making the lady bugs in this project, genetic variety is very important. First of all, without genetic variety everything looks the same. For example, in the reebops, if the first generation or the parent bug was a red eyes which was recessive, and the bug breeded with a black eyed dominent bug, the black eyes will be dominent. Then if the other bug which the origional parent bug breeded with was hetrozygous, the children of the bugs have a 25%chance of being red eyed. I had an ugly bug born in my fourth generation The bug had no wings, yellow mutation and no dots with short legs. This did not look very good compared to the previous bugs of mine. Sooo, if you think you are ugly, blame your parents for having you the way you are.

Genetic diseases are heredity. So, for example, if both the parents of a bug had familial Dysautonomia, the bug will probably get the disease depending wether if the parent is homozygous or hetrozygous.

If you think you are special, and maybe you are, without genetic variety, every one would be special with your talent. You will not be very special then.

During the mating, we sometimes had the same color for our chromosomes, so we had to use some type of symbol to repersent our own chromosome. Therefore, we are a little different. Without variety, we are all the same. These are pictures of bugs that look alike but are tottaly different to prove my point.(top)

This week in science;

on Monday, we talked about incomplete dominence, or which the child is a mix of both the parents.

This is a really cool site that told me a lot about incomplete dominence:::

The next day, i got a migrane and had to miss the first 4 periods of school, so this is what i learnt from that day:when you have 2 dominance for a trait, it becomes a co-dominant. This happens in blood when there is two DOMINANT blood types mixed like A and B (AB).Then on top of that, there is the proteins that attach on to the blood types.(positive and negative.) The positive always is the dominant one.
I don't know what happened the rest of hte week in science.

This week in science, we did many things, First on Monday, we had a snow day, on tuesday, we learnt on how the Class' results did almost support the whole school's results.
On Wednesday, we went over some of the things about Genetics. Then Finley told us some things about the Lab that we will be doing th enext day. We created "egg and sperm cells for the experiment."
On thursday, we learnt that the Genetic Mutation always results in the strand mutated becoming the Dominant Gene.
On Friday, we did the experimen of mixing uop sperm and egg cells and looking at what the outcomes would look like. Then we had a quiz that we had to do at home whch I just hot to see.
This is what tje quiz was

Spiderman and Spidergirl got married and soon found out that
Spidergirl was expecting a son. Spiderman couldn't wait to
welcome his new son into the world and was looking forward
to fighting crime with him. However, when he was born
Spiderman realized that his son does not have his parents'
"spider" quality. Spiderman believes that the baby might
actually be Batman's! (Remember, Batman has ZERO special powers)

What do you know about the "spider" trait?

What could spiderman and spidergirl's genotypes be?

Did spidergirl have batman's baby? Support your answer with an explanation

Hard Quiz.

Science

This week in science, we learnt how to make a punnet square and what a Homozygous or a Hetrozygues is.
A homozygues is a species that has the same trate from the mom's side and the Dad's side.
A hetrozggues is a species that has two different trates. One from the Dad's side and one on the mom's side.
The recessive trait is always the trait that does not take over unless there are two rrecessive traits, which makes it a homozygues.
If hter is a dominent gene and a recessive gene, the dominent gene always takes over.
This is a great video that i found that helped me understand Genetics.
