this week we started learning about DNA and RNA!! We learned about ADANINE, THYNINE, CYTOSINE, AND GUAYNINE. '

ADANINE ONLY GOES WITH THYNINE AND GUAYNINE ONLY GOES WITH CYNINE

LATER ON WE PLAYED A GAME I GUESS IS WHAT YOU CAN CALL IT AND WE GOT TO SEE HOW THE PRODUCT IS MADE?

DNA MEANS DEOXYRIBOSENUCLEICACID

RNA MEANS RIBOSENUCLEICACID

rna is like half of dna

the one on the right is dna and th left is rna. RNA has one backbone and Dna has two. Dna starts with a certain base its ATCG and RNA is AUGC. OH i forgot to mention that U STANDS FOR URACILE. URACILE IS ONLY IN RNA AND IT ONLY GOES WITH ADANINE.-

ATP= energy.

homework

i have no clue what to right because i have no clue what week we are on but ill give it a try.



this week we learned about respiration, photosynthesis, and fermantation.



photosynthesis- the synthesis of complex organic materials, esp. carbohydrates, from carbon dioxide, water, and inorganic salts, using sunlight as the source of energy and with the aid of chlorophyll and associated pigments.


PHOTOSYNTHESIS
h2O + CO2 + LIGHT -------> C6 + H12 + O6 + 02


RESPIRATION:

C6 + H12 + 06 + O2 ------> CO2 + H2O + ENERGY

FERMENTATION--- RESPIRATION WITH OXYGEN


SUGER --> C6 + H12 + O6

WE ALSO LEARNED ABOUT DNA.

- ITS TORNADO SHAPED
-LARGE MOLICULE
-NUCLEUS IS WERE ITS FOUND
THE REAL WORD FOR DNA IS DEOXYRIBONUCLEIC acid

i have no clue what week it is--- SCIENCE HW

this week we started on what an organism was. we had a disscussion in class, and my opinion of a organism was that an organism is a living thing.For example animal, plants, etc. and example of a non-organism is... minerals and water.

this is what i thought since we were talking about potato cells as our example!


an organism is ------> living
a potato is ----------> living
potato cells are in the ----> potato a potato is ----> living ------living means---> organism


Finally we came to a conclusion an organism one or more cells that can independantly sustain life.

after we finished our discusion the next day we learned about prokaryotic and eukaryotic.

a prokaryotic cell is a cell that has no nuclus, a ribosome but no membrane,e. coli and bacteria are examples of prokaryotic.

eukaryotic- is any organiasm that has a nuclus is complex, has membane organelle .
ex. plant cell -> potato
cheek cell -> animal cell


then later we started on working on photosynthesis we did a expirament with why plants need photosynthesis.
we learned about atoms, typles o0f sugers( like glucose and galacose ) we learned about alot of things this week.

i dont have to blog!!!!!!!!!!

I DON'T HAVE TO BLOG!!!!!!!!!!!!!! ( fyi this was supposed to be for last weeks hw)

science hw 11/5/09

this week we didn't do alot, because it was only a three day week, but.....

this week so far we have learned about organelles and their functions.

we made a chart and a Venn-diagram with 3 circles.

this week we also learned about paramecium's, a yesterday we tried to look for some paramecium in pond water. we looked under a microscope my partner was Yolanda.

i will add some more stuff tomorrow( Friday)

10/31/09 hw

last week i was out :(

This week we started working on cheek cells( animal cells), and plant cells.
We magnified our cheek cells and talked about what kind of cells they were.
We answered questions like:

1. what is the inside of your cheek cell made of?
2. what do you think the other parts of your body are made of?
3. where you able to detect and organelles in your cheek cell? What organelles might you have seen?
4. How are these cells similar and different from the bacteria cells we have been studying?

For are skin cells we did an experiment, we took a sample of our cheek cell by rubbing a swab up and down the inside of our cheek. After that we took a slide and some blue dye stuff that i forget what its called, and we put a drop or two on the slide. Then we took the swab with the cheek cells on it and mixed it with the blue dye. We then took a cover slip and put it on top of the slide. We had a microscope set up on the table already and we then put the slide under the stage clips of the microscope. We saw our cheek cells it looked really cool, some of the cheek cells were folded and perfectly straight. You can see in the picture to the left. After that me and my partner Jillian did the same thing but just with water. In my opinion it was easier to see the cells with the blue dye. We did both procedures in high and low magnification.



I think the day after we talked about what kind of cell a cheek cell was, we found out it was a animal cell. People/humans are animals so it make sense.

For homework that day we had to research plant and animal cells. We also had to draw a picture, the picture to the right is an animal cell and on the left a plant cell.










After learning about animal and plant cells we did the same thing as the cheek cells but instead of cheek cells, we used a potato and grass we stared working on plant cells! the only different thing was using a potato and grass, also we added orange. So the same thing was blue dye, water, high and low magnification. The picture on the right is a potato cell i couldn't find a picture of a grass cell.









So basically we have been learning about cells this whole week!!
i learned this by paying attention in class and working with classmates, and i could use this in the future by knowing what it means when I'm asked.

science homework

this week we learned about a few things. We learned about an organism.

Also This week we had to continue helping the nearby schools with finding out why there students have been getting sick. Me and my group were going to test the pan for bacteria but the pan was gone. But the pond water was still there to test so me and the group but a drop of water under a slide and and looked at the drop through a microscope. In that one drop we found a alot of things. We found a dead organism and a little tiny organism that was alive.

also this week for homework we had to do something on simulations. A simulation is a picture that like describes a situation or transformation a stage of something . It gives you an idea of something , its like a story up close.

• How did you learn these ideas?
  
  
  I learned these ideas by doing my homework and listening during class
  
  
  • Why is it important to know this idea (What real world application is there)?
    
    
    its important to know these things because you can use them in the future.
