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.

science HW 10/7/09

• What science ideas did you learn?
  
  
  This week we learned about the structures of a bacteria and a virus.For homework we had to draw a picture and label the structure. We had to look at the qualities to see if the structure is living or non living.
  If it is living it would have to....
  
  
  -respirate ( breathe )
  -have food
  -reproduce
  -have DNA or RNA
  -a cell wall
  -adapts to its environment
  
  
  
  
  Also in class we are helping a school to see why there students are becoming sick. We got blood samples, lake water samples, and chicken samples. towards the end of the week we kinda learned about a microscope, and how to make dry and wet mount slides.
  
  
• How did you learn these ideas?
  
  
  i learned these by discussing with my group and learning from my homework, also listening to my teachers and other things.
  
  
• Why is it important to know this idea (What real world application is there?)
  
  
  learning how a virus works is good to know same for bacteria. When i grow up i want to be a pathologist. A pathologist is a kind of doctor. Its good to know these things cause its 1 thing more you ll know more about.
  
  
  
  
  
  

week 3 october 3

What science ideas did you learn??

In science we have been learning about the spread of disease. This week we have been doing this activity. In this activity we have been helping this school. We are trying to figure out why kids have been getting sick, and what they have.

We had also did an experiment on simulation and learned about macroscopic, microscopic, and sub-microscopic. We had also learned about dirty and clean surfaces and how you can experiment and see what's dirty and what's not.

How did you learn these ideas?

We learned these ideas by discussing and doing experiments. The experiment we did on the simulation, was for homework we went on this website and it would show us simulations.A simulation is an imitation or enactment, as of something anticipated or in testing. A simulation can show toy the object up close.

Why is it important to know this idea (What real world application is there)?

It is important to know these ideas because we could use them in real world situations. Like for example in the future someone can ask you about the spread of disease, and you would know the answer for that.
