Monday September 14th Instructions for Sub and class

2nd period planning

1st and 3rd block, AP Environmental Science:

Someone from 1st block: will you please feed my fish (both tanks)?! 

NEXT: Make  eco-column observations.






Then: work on your lab write -ups!
You need to write up the soil texture lab (the one where you layered the different soil types and ran dye through them ) and the bulk density lab (not the weathering one though!)

Finally:
FINISH Math Packet! Remember, no calculators :)!

They are in a folder on my Big desk.



4th block biology class: 
watch this, complete the worksheet that goes with it (it's in a folder with your class roster on the table behind my green chair :)

Vocab is due on Tuesday

NO article due next week!

Test on the cycles, atmosphere and the greenhouse effect on Thursday.

Hot cocoa Friday!!! Bring in your own mugs- No styrofoam! Click link to find out why !

Allan Savory TED for anyone that may have missed it!

BIOLOGY CELL VIDEO

Biology students need to watch this video clip and answer the questions I gave you in class as you go.

APES- soil test corrections and extra credit due this Friday: 9-11-15

Soil Test re-takes or test corrections need to be completed by Friday.
If you are going to complete the extra credit activity at home, it is also due by Friday!

Here's the link to the lab if you didn't pick it up in class:

REMEMBER TO COMPLETE ALL PARTS, TAKE PIX OF YOUR BALL!

Biology word list- Cells- due September 15th 2015 (Tuesday)

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. Eukaryotic cells- have membrane organelles, in particular a nucleus that holds its DNA. Animals, Plants, Fungi and Protists are made of these types of cells. They are thought to be a symbiotic relationship between cells that were once prokaryotic. 
15.Prokaryotic cells- Don not have membrane bound organelles. They have DNA, but it is not kept inside of a nucleus, it is in the shape of a plasmid (circular) that floats around in the cell. ONLY BACTERIA are Prokaryotic
16. Euglena- a photosynthetic organism that lives in water. It has Chloroplasts and other organelles and is a unicellular (one celled) organisms made of cells like us- Eukaryotic! (It is a protist)
17. Paramecium- a one celled organism (protist) that swims (it also lives in water) using its cilia. It eats other organisms to survive.
18. Contractile vacuole- organelle in protists that helps them maintain proper water balance by helping to pump out excess water. They need this since they live in the water.
19. Plasmid- a circular strand of DNA found in bacteria.
20. Golgi body- organelle responsible for packaging substances made or excreted by your cells.
