REVIEW QUESTION and ANSWER PAGE

Hello my grade 9's.

Well the term is officially done, and I hope that you have had a wee bit of fun and don't think that science is boering anymore. I know I have enjoyed the time and things that I have learned from and about all of you.

We have had some special times from our first quiz (98% class average), to winning the pumkin carving contest, to then scarfing down a lot of pizzaand a few pops. Learning how chemicals can change things in a lab, to how we have changed our own community by bringing in 500 + cans to win yet another food prize.

We have faced and challenged the shockingly-crazy circle of death and survived. ( Well except that exchange student, poor soul they will be missed, but in away it gave us one more of those dreaded yet all important microviewer to do a lab in partners.) I have learned that a few of you will consume vast amounts of doghnuts only if there were fewer calories, while other shoveled them in so quick they almost sucked in their own hand! YIKES! Ahhh but alas, with the last day today of playing SIMPARDY the final exam review, and some people being scared and fearful of hippo-sequptiously-potomus-phobia ( what ever that was?) is complete and so is this course. I thank you all for a great semister and again thank you for all the great things we have shared.

I hope that each and everyone of you has learned someting from myself, the class and the course.
No, seriously, you better have learned something from this course as the exam is FEB 2nd at 8:00am.

Just incase you haven't or need that little bit of encouragement or help I am making our last blog page.
This page is so you can quiz one another, answer each others questions or in dire need ask me to clarify something, as I will not give anything up about the exam except this:

100 Questions all scan tron, so make sure you bring a pencil, a good eraser and a calculator.

GOOD LUCK! Hope to see you in the hallways, and hopefully not running in the opposite direction away screaming...lookout here is that weird science guy again.

A BRAIN BREAK

Hello my students.

Here is a great website to help you unwind a little to eleviate the stress of culminating activities and exams. Everyone needs a good 15 min giggle and some fun.

Play the mission it actually has some great science games to help you study to. Space stuff, electricity stuff, some chemistry stuff. You'll actually have so much fun and not even realize you are learning or studying alittle too.

THE SUN AND OUR PLANETS

Today in class we learned the correct order of our 9 planets starting at the centre of our solar system ( the sun) and traveling away from it. Please note you will have to know this and any other types of materials or structures that belong in space as well. ( Meteors, comets, asteroids, ect)

THE SUN

The sun is our planets source for heat and light. Without the sun we would not have any energy to live adn therefore we would be non-exsistant without it.
To give you a better idea on how large our yellow star ( the sun) is we can fit approximately 1.33 million planet earths inside the sun to fill up its volume.

The sun is made up of 2 types of gases. Hydrogen and Helium.
The sun is constantly undergoing nuclear reactions called fusion. What is happening because of the great temperature of the sun ( its core is 15, 000, 000 degrees Celsius) and the pressure of gravity is is converting its hydrogen gas into helium gas. The core of the sun is made up of helium. Just to give you an idea on how much gas is being changed, the sun is converting 600 tonns of hydrogen every second.

Next week you will learn what is goingto happen to our yellow star ( the sun) when there is no hydrogen left to burn. It is going to amaze you!

PARTS OF THE SUN:

1. The core - the area of the sun where nuclear reactions (fusion) takes place. It is in the centre of the sun

2. The photosphere - this region is located just under the outer layer of the sun. This is where light originates from and the temperature of this layer is about 6,000 degrees Celsius.

3. Solar flares - these are usually beside the sun spots and are areas that release subatomic particles and energy.

4. Sun spots - these are teh darker areas of the sun's surface. THis happens beacuse these spots are actually cooler than the surrounding area. Sun spots cycle about every 11 years. In this year of 2005 we are able to see many more of them.

5. The corona - the outer atmosphere layer of the esun. This can be seen clearly during an eclipse. It resembles the top flame colours of a candle. However, the coronas temperature is about a 1, 000, 000 degrees Celsius.

6. Solar prominences - these are streams or jets of gas that arch into space from the sun. They can reach up to a few thousand kilometers in size.


HOMEWORK:

Please read and take notes on pg 435 to 442 on the two models of the solar system.
Please answer questions 1 - 5 on pg 442.

For further reading please read pg 443 - 445 to get an over view of the sun and the correct arrangemt of the 9 planets in order.
