=**R**__A. Cells and Organ Systems__= .. 1. How our cells are organized? === Cells make Tissues (blood is a tissue) Tissues make organ (heart, stomach, lung, blood vessels and skin are all organs) Organs make Organ Systems ===

2 .What makes up a animal and plant cell? What is the difference between animal and plant Cells?



= = __ PLANTS ONLY __

__ Cell Wall: __ “ Support System” The cell wall supports the plant cell.

__ Huge Vacuole: __ 

3 . Know the 4 different parts of blood and their volume
=== A. Blood. Blood has four parts. Red Blood Cell- 44% of blood and carries oxygen and carbon dioxide White Blood Cell -- less than 1%. Fights infection. Plasma-- 55% of blood. Carries all blood parts around the blood vessels and helps in clotting blood. Platelets -- Less than 1% of blood. Clots blood when cut. B. Vessels: Arties are big, thick and strong. Carry blood away from the heart. Vein are thin and elastic,have one way valves, carry blood back to the heart. Cappiliaries are very small and thin .. blood travels through them in single file. Able to pass oxygen and carbon dioxide through into the cells. c. Heart ===

4. Know the the 3 difference vessels used to transport Blood

6. How does blood flow through the heart and body? as the heart expands and contracts, it pumps blood through the arteries throughout your body. The blood flows through your body, then the O2 gets sucked out of the blood cells by the cappiliaries. then it goes into the veins then back to the heart.

7. What are the different parts of the Respiratory System?

==

A fluid is matter that flows.
===Flow means that a matter can move from one container to another taking the shape of the container.===

No air space in fluid.
Examples.

__Viscosity__
===**Viscosity is the measure of how fast a fluid can flow. How thick or thin a fluid is.**===
 * High Viscosity= slow flow= High density eg maple syrup
 * Low Viscosity = Faster flow= Lower density. eg water

Demos

 * Dancing Dime
 * pulse metre or the love metre!
 * Imploding can. see demo below

=C. Water Systems= The transformation of water from a liquid into a gas, a process which humidifies the atmosphere. The transformation of water from a gas into a liquid The movement of water through the atmosphere. The transfer of water from the atmosphere to land. Rain, snow, hail, sleet, and freezing rain are discussed. Water located below ground Transfer of water to the atmosphere by plants and vegetation. Rivers, lakes, and streams transport water from land to the oceans. Too much rainfall can cause excess runoff, or flooding. A brief encapsulation of the hydrologic cycle, plus an example of the hydrologic cycle at work.
 * 1) Water cycle. What are the parts of the water cycle?
 * Condensation**]]
 * Transport**]]
 * Precipitation**]]
 * Groundwater**]]
 * Transpiration**]]
 * Runoff**]]
 * Summary and Example**]]
 * 1) Ocean currents … gulf stream
 * 2) Water temp influences temps...
 * 3) Water sheds in North America
 * 4) River features… // meanders, oxbows, alluvial deposits, flood plains, deltas //
 * 5) Calculate which river is more mature.
 * 6) Name the different ways to treat water so you can drink it.

20. Know how to fix near sightedness and far sightedness
 * filtration-** filtering water to get the little things out **floculation/sedementation-** is when you put a chemical in the water to make the bad things to stik togeather and sink. **ion exchange-** a megnet is put into the water to take out all the meatil **absorption-** charcoal is placed into the water to get rid of courling, bad tast, organic contaminants and smell. **disinfection-** clorean is put in the water to distroy bactera. __D. Optics__=====
 * 1) Incandescent- gives off light and heat
 * 2) Fluorescent- electrisity hits vaper, vaper gets exsited, vaper hits coating, coating glows.
 * 3) Phosphorescent- made from phospher glows in the dark.
 * 4) Bioluminescent- animauls that glow i.e. Fire Fly
 * 5) Chemiluscent- cemical reaction that glaws i.e. glow sticks
 * 6) Primary Colours- Red Blue Green
 * 7) Secondary Colours- created by two primary colours i.e. Red + Green = yellow Green + Blue= Cyane Red + Blue = M egenta
 * 8) Complementary colours- when two colours are mixed togeather to make white i.e. Megenta + Green= White
 * 9) Rods and cones- Rods= Brightness Cones= Colour
 * 10) Law of reflection- The law of reflection says that you see your reflection because are at an equal distance from center of the interference as the light that reflects your image.
 * 11) Concave [[image:http://www.physics.uiowa.edu/~umallik/adventure/geo-optics/lenses.gif width="372" height="275"]] convex
 * 12) Parts of the eye, iris, lens, retina, [[image:http://www.meritcare.com/healtheducation/familyhealth/images/kid/body/images_53993/1078927948547.K_eye_diagram.gif width="206" height="106"]]

 =__E. Scientific Process.__= You will be information to create a lab. Make sure you know the proper way to write a lab. The question is who has a better memory, Grade 7 or grade 8?

The experiment will be playing the Game Simon. You will need to write a lab with this question during the exam. You will be given the average level for each grade.
