Hey everyone, I apologize for being out this past week!
It looks like this first 6 weeks has been a little bumpy, with my kids getting the flu and then with me sick Thurs and Fri. Hopefully the rest of the semester will be uneventful in terms of illness for my family and for yours.
Incase you are wondering, I was in the hospital Thurs. and left Friday morning. I had/have vertigo that the doctors feel is a result of being exposed to a virus (remember my daughter had the flu a week ago!). It's an awful, awful thing to have and I hope none of you EVER experience it!
We have a lot to cover in the week ahead with the Benchmark on Friday.
Here's my tentative schedule for the week.
Monday- Organic compounds test- you can use your poster! it will be short! You will then work on your new list of terms that are due on Thursday.
Tuesday- Focus will be exclusively on the plant and animal cell structures, you will draw them and do anaolgies to help you remember the more important organelles.
Wednesday- we will wrap up "cells" and begin cell transport. you will receive a packet that you will sketch your way through in order to reinforce the various types of cell transport.
Thursday- we will wrap up transport and review for your benchmark.
Friday- we will take your benchmark and then plant some seeds!

WORD LIST FOR 3-3-11
Word list 5:
YOU won't have a quiz on these, but you must do all 15 terms!!!
They'll be due on THURSDAY (3-3-11) and you'll have class time tomorrow to get started on them.
1.Chloroplast- organelle found only in plant cells, it makes chemical energy (sugar/ glucose) using solar energy (sunlight) to combine water and carbon dioxide.
2.Mitochondrion (singular) - responsible for breaking down sugar (glucose from plants) into a more usable form (ATP) for our cells. Found in animal cells and plant cells. Cells that do more work have more mitochondria in their cells (muscle cells and sperm cells have the most!).
3.Centrioles- organelles found only in animal cells that are only active during cell division (mitosis) where their job is to make sure that duplicated DNA strands get pulled apart evenly.
4.Ribosomes- found in plant and animal cells, they are responsible for building proteins and enzymes in a cell by using instructions they receive from the DNA via an RNA strand.
5.Nucleus- the control center for the cell, it contains the DNA instructions used to make every part of your body, your DNA NEVER,NEVER, NEVER leaves the nucleus!!
6.Cell wall- found only in plants, it provides structure and support to plant cells.
7.Cell or plasma membrane- found in plant and animal cells, it controls the movement of all substances in and out of the cell. SUPER IMPORTANT!
8.Cytoplasm- gel-like substance that all of the organelles are suspended in, it provides a medium for nutrient exchange as well as a cushion for the organelles.
9. Active transport- transport of a substance across the cell membrane that requires energy!! When something moves from where there is less of a it t0 where there is more of it. This usually takes work. Imagine you are trying to push the last little bit of a sleeping bag into it's case.
10. diffusion or passive transport- transport of a substance across a cell membrane, this type does not require energy because the substance is usually small, like oxygen, and moving from where there is more of it to where there is less of it (with the concentration gradient). imagine a ball rolling drown a hill - from where it is highest to where it is lowest- no energy needed.
11. facilitated diffusion- this is a lot like passive transport in that it doesn't require energy. It does however require a door called a protein channel. this is because the substances are usually large, like a sugar molecule. These substances move with the concentration gradient (high to low) as well.
12. Osmosis (or diffusion of water)- is the movement of water (only water) across a cell membrane- this works with the concentration gradient as well, moving from where there is more water to where there is less. It does not require energy! ** note- water usually follows salt! If you've ever eaten too much salty popcorn at the movies you may have noticed that your hands get puffy. Your cells are soaking up fluids to balance out the salt in your cells. this is an example of how your body carries out homeostasis!
13. Fluid mosaic model- this refers to the way your cell membrane is made, it is made up of two floating layers composed of proteins and lipids. the membrane is constantly moving which allows substances to glide through it. the lipid layers insure that the water level in your cells is controlled- the inside lipid (fat)Layer holds the water in, the outside lipid (fat) layer keeps water out. the protein channels are like tunnels that take substances from one side of the cell all the way across both layers to the other side of the cell.
14. Mitosis- the process of forming two new, genetically identical cells (skin, liver, hair, muscle, blood, etc. all of these cells are referred to as being 2N= the whole chromosome number, one set from Mom and one set from Dad.
15. Meiosis – the process of forming 4 new, GENETICALLY DIFFERENT cells with half the genetic material of the original cell. These cells only have 23 chromosomes (they are called 1N)

Window panes for 2-23-11
Since we will be spending next week reinforcing the topic of Organic Compounds you will have an alternate homework assignment ( your 5 th word list is on cell organelles which we haven't started yet!).
Your homework for Tuesday is to bring in pictures (from magazines, the computer, your own pix or your groceries) for your group of everything you can find that relates to Organic compounds!!!!
Examples: a picture of a stick of butter would represent a LIPID, a picture of a steak would represent a PROTEIN, a picture of a nucleotide or a blue print would represent NUCLEIC ACIDS (DNA or RNA), and a picture of a lolipop would represent CARBOHYDRATES! Get creative!! think outside of the box!
YOU'LL be making posters in class and using your pictures to illustrate the organic compounds.
REMEMBER- THE BETTER YOUR POSTER, THE EASIER YOUR TEST WILL SEEM!
HAVE A GREAT WEEKEND!

NEED SOME EXTRA POINTS?
Extra Credit guidelines
Here's what you do:Watch a documentary that is "life science" based.
While physics, astronomy and chemistry are useful and interesting, they won't help you in my class.
Examples of good programs are things you might find on National geographic, pbs, bbc, animal planet, planet green and the science channel.
Many of these programs can be watched on your computer at your leisure.
You can complete four per each 6 week grading period.
You are basically summarizing what you watched.
Write a sentence or two during commercials, or every 10 minutes if it's online, to describe what's happening in the documentary.
At the end let me know the overall purpose or intent of the documentary and what you got out of it. It's meant to be a reflection on what you just watched.
TRY TO CHOOSE THINGS THAT WILL HELP YOU IN MY CLASS!
Topics we'll be covering in class: the cell, genetics, heredity, ecology, organic compounds, health and disease, classification of living organism, protein synthesis, plant structure and reproduction.
MAN VS. WILD is acceptable once every 6 weeks grading period.
(NOT MYTHBUSTERS, sorry)
ANYTHING ON GENETICS IS GOLDEN!!!!! I MAY EVEN UP YOUR POINTS EARNED IF YOU CHOOSE THIS TOPIC!! ENJOY! Check out this site:http://www.pbs.org/wgbh/nova/programs/int_natu.htmlhttp://video.pbs.org/subject/957383555/topic/957388344/viewmode/gridCheck out any 30 minute combination of the environment videos listed on the left and you have basically watched a 1 hour program on tv.http://video.nationalgeographic.com/video/player/environment/habitats-environment/freshwater/env-freshwater-whycare.html

ORGANIC COMPOUNDS WORD LIST!
DUE WEDNESDAY (2-16-11)
Fourth list Do 10 of the 20—DO THE ONES YOU THINK ARE HARD BECAUSE YOU WILL BE QUIZZED ON ALL 20!!!!!!!
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.

Third set of window pane terms
Biology terms #3 NOTICE: you only have 10 words this time so you must do them all!
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.

What's in your plastic cup/bottle?
Check this out to understand why I don't let you have water/soda bottles in class (aside from the fact that they pollute our environment).
A "safe" reusable container means that it was intended for repeated use and therefore made of "safe-R" material.
