Cell project

Ok so, your cell project is due on March 5th and it is basically an art project using biology content. I expect you to sketch and then color your cells (10 of them as listed on your rubric). You will need to label the organelles in all of your sketches.

The best way to find the cells is to google images and have sketch or diagram in the search bar.
 example; "euglena sketch"







This is a great example of a euglena cell- you will be able to find similar sketches for a cell types.


Great Protist overview:

What we've been up to this week , TEST next Week on organic compounds, cell transport and Cells

Shelby,We Hope You Are feeling better soon! If you want to do the egg lab at home, just put an egg in vinegar over night ( a raw egg). The next day, pour out the vinegar and put the egg in syrup over night and check out what happened to your egg! Next, clean out the syrup and put the egg in pure water, you'll see a difference in a few hours.


Osmosis and the egg!
Egg in syrup = Egg shrivels, like your lips when you eat salty food!
Tomorrow we'll see what happened over night with the Egg in Water, what's your best guess?

WE covered a lot of information about Organic Compounds:check out this link for a refresher
http://www.ibiblio.org/virtualcell/textbook/chapter2/chapter2.htm

THis is more detailed information for anyone who may have missed a few days, it's more detailed thatn you need in some parts, but it's better than coming back not knowing what we are talking about.
www.bios.niu.edu/johns/bios103/Organic%20Compounds.ppt



WE covered cell transport: passive transport = Simple Diffusion, facilitated diffusion and Osmosis
Active transport= is requires energy and moves material against the concentration gradient, like you riding a bike up hill

check out this link for clarification:

We will start  cell types on Friday, go to the virtual cell for help with that!

New window pane list for organic compounds due 2-15-12

Thanks to Shane you get an extra day for window panes- now due Wednesday 2-15-12

window panes for Organic compounds:


1. Carbohydrate- organic compound made up of carbon, hydrogen and oxygen atoms whose primary job is to provide a quick source of energy to the organisms that consume it.

2. Lipid- organic compound made up of carbon, hydrogen, and oxygen. It has two main purposes in organisms: provide storage for energy and build membranes ( thin covering around all of your cells).

3. Protein- organic compound made up of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur atoms. The main jobs of proteins are: to build tissue in the body, to make up hormones and to build enzymes.

4. Nucleic acids- organic compounds made up of carbon, hydrogen, oxygen, nitrogen and phosphorous. The main job of these compounds is to carry our genetic code which determines everything that is made in our bodies. Examples are DNA ( deoxyribonucleic acid) and RNA ( ribonucleic acid)

5.Hormone- a chemical signal (made out of proteins) that travels through our bloodstream and lets other parts of our body know how to grow or what to make. (ex. progesterone- a hormone that is active in pregnant women and helps to prepare the mom's body to hold and care for a baby).

6. Enzyme- a type of protein that is responsible for helping to speed up chemical reactions in our body. In chemistry, or in reactions outside of our body, this is called a catalyst.

7. monosaccharide- a simple sugar (carbohydrate), this is a sugar composed of only one molecule- glucose is a monsaccharide. (mono=one)

8. polysaccharide- a type of sugar made up of a long chain of single sugars. (poly = many)

9. cellulose- a type of sugar found only in plants, it helps to build outer coverings of vegetation ( the yellow shell of each little piece of corn is made of this). we can not digest cellulose.

10. Starch- a complex carbohydrate made up a really long chain of glucose molecules. This is the form that plants store their sugar in.

11.Insulin- a hormone made in the pancrease that helps break down sugar in the body.

12.Hemoglobin- a protein that makes up your blood, it carries iron and oxygen ( you can normally carry 4 molecules of oxygen on each cell).

13. Glycogen- the stored form of glucose, it is stored in our liver.

14.monomer- a molecule that exists by itself - only one molecule of something = glucose

15. polymer- a molecule that exists as a long chain of monomers connected by bonds= starch

16. Organic compounds- compounds that have the element carbon as the central/ essential connection.

17. atom- smallest unit of an element.

18. nucleotide- smalles functional unit (or piece) of a nucleic acid. It consists of a sugar, a phosphate and a nitrogen base.

19. double helix- the shape of a DNA molecule, it resembles a twisted ladder.

20. single helix- the shape of a RNA molecule, it resembles half of a twisted ladder

Rough Draft and window panes bumped one day-FONT FOR PAPER

I have to go to a Teacher Conference on Monday 2-6-12, I'll be out the entire day.
This means that you don't have to turn in your Rough Draft until Tuesday 2-7-12
and that Your window panes have been bumped to Wednesday 2-8-12.

Enjoy the video and the sub., you'll have time in class (monday) after the video to work on your window panes!

also, I had a question about font and font size, I like Calibri at 11pt font. It should be single or 1.15 spacing (that should make-up for the font size!)

new word list due next Tuesday 2-7-12

1.Logistic growth- when a population of organisms grows at a steady pace until it reaches its carrying capacity, then it levels off. (graph with an s-curve)


2.Exponential growth- when a population of organisms grows very rapidly because it has unlimited resources ( graph with a j-curve)

3.Stewardship- when people take responsibility for their environment and do things to minimize the negative impact humans have on the environment- like a protector for the environment.

4.Sustainable practices- using energy sources that are renewable and that don’t harm the environment. (wind power, hydroelectric power and solar power are examples of sustainable practices).

5.Invasive species-

http://www.ouramazingplanet.com/alien-invaders-destructive-invasive-species-0299/

organisms that currently live in an area they are not naturally found, they do not have any natural predators and can grow out of control- they usually take over the habitat of another organism that is normally found in the area. (examples are: fire ants, kudzu, rabbits in Australia, the cane toad, northern snakehead)- they are a bad thing!

6.Bioaccumulation- a build up of toxins in the tissue of an organism from exposure to the toxin in their environment and the food they eat ( top predators are most affected).

7.Acid rain=
http://www.epa.gov/acidrain/education/site_students/whatisacid.html
sulfur dioxide and nitrogen oxides mix together to turn rain acidic- tree tops in the mountains look as if they have been burned, stone buildings begin to crumble and erode more quickly.

8.Greenhouse effect- when Ultraviolet (UV) rays enter the Earth’s atmosphere, some rays stay and some will bounce back out. This allows our planet to have a relatively stable temperature- it minimizes huge temperature shifts, this allows plants and animals to adapt more successfully to their environment.

9.Climate change- when the patterns of temperature and weather change over a large area due to “global warming” which is contributed to a build up of carbon dioxide and other “greenhouse” gases in our atmosphere- this makes it hard for the UV radiation to bounce out!

10.Deforestation- when a large wooded area is cleared, either by “clear cutting” or burning, this results in greater amounts of carbon dioxide accumulation in the atmosphere and less habitat for organisms.

Honors paper info.

Your paper needs to be 6 pages typed total, remember that 25% of each page can contain a picture and at least one page needs to have a graph.

your rough draft should be your notes on each of the 5 sections you are addressing as well as your introduction and conclusion thoughts. It does not have to be a formally handwritten paper, it can be simply your topic and then the notes you have so far on your topic. It does not need to be excessively long because I am assuming that your notes won't be in complete, formal sentences.


Your notes DO need to be handwritten (unless your writing hand is in a cast or brace of some sort).

You do not need an outline as I have given you the outline I want you to follow.
Introduction
What causes climate change?
History and future of climate change.
How are countries affected (4)?
What are some countries  (4 of your choice) doing to curb climate change?
Conclusion.

hope this helps.

first window pane word list for Spring semester/ print this and the previous post for your homework tonight!

Don't forget, print this post and the previous post "second semester biology students" for your homework tonight.

Directions for WINDOW PANES:


all terms should be in your small notebook.
Your name should be on the front of your notebook. Each page should be divided into 4 "windows", number each term in the top left corner of the "window".

Attach your word list to the first page using staples then start a new page for your terms.

You may only use colored pencils in your illustrations, but YELLOW should not be used (unless it's to hi-light something)

In the top left square Write the term.

In the top right square give a synonym (example) or antonym for the term. (remember it doesn't have to be a literal synonym! )  Let me know whether your term is a synonym or antonym by placing an "S" or an "A" in front of the term.

For the word OBSERVATION a synonym could be smelling since using any of our senses is a way to make an observation in science.


In the bottom left square describe the term using your own words.

In the bottom right square give an illustration of the term (don't draw a picture of the antonym!)

If you are not comfortable with drawing, you can create a multiple choice question for the term.
