This blog will unfortunately be coming to a close. TDSB has a new system that has a blogging feature and I will likely be using that more often. It is unfortunate as this one has been a lot of fun and some really interesting things have been written by my students. Thank you all who took time to post regularly. Enjoy yourselves and keep writing.

Well, I last posted in February. (You may insert a sheepish inflection of something like it.)
I also realize I should probably get fired for not having posted in so long. If Mr. Foster is reading this, then hopefully he won't fire me, 'cause, you know, that would be a little bad.
Moving on, plenty of things happened these past three months. Whether or not is important is up to you.
1) Made All-City. Concert's next month at Massey Hall. Yay.
2) Went on a trip for March Break. Lost my DS Lite, freaked out, found it. Yay.
3) Grandma kicked the bucket. Definitely not-yay. Good food at the funeral, at least.
4) Attempted to learn Python. Failed epically. Not-yay. (Those scripting languages are so confusing. How do people do it?)
5) Tried again. Not giving up! Yay.
And that's pretty much it. Oh, and there was plenty of poor time management in there too. Er...have a nice day?

Hooray For Long Weekends!

As you all know, Monday is Family Day, meaning no school! I'm sure you're all as glad as I am about this, as it's just one more day I can sleep in.

To kick off the weekend, I went to see a movie on Friday night with some friends. The twelfth of February was the day Percy Jackson and the Olympians: The Lightning Thief came out, so of course, that's what we went to see. The movie, based off the popular series by Rick Riordan, was amazing! I'm still getting over it. So, if you haven't read the books, go read them now. If you haven't seen the movie, go by a ticket and see it.
Today (Saturday) was spent at home cleaning up my monkeys' - I mean brothers' mess. Lugging a vacuum up three flights of stairs is not fun. Not fun at all. That was just the morning though. It was the afternoon that was the hi-light of my day. I spent the entire time loafing around, because that's what weekends are for, right? Right!

I hope you all have a great long weekend!

How to: measure volume, density, and mass.

How do you measure the volume of an object if it is too large for you to take a ruler and use a formula? Firstly take the object that you are going to find the volume of put this object in a liquid, the amount that the water or liquids grows by is the volume of your object.

Density:

You can calculate density by dividing the volume by mass.

m

-

v

Mass:

Refer to my last post.

Finish your homework, which is due on monday.

MASS? WEIGHT?

First when you hear the word MASS you probably think of the word massive and come up with one conclusion, whatever your talking about must be HUGE, right? WRONG. Mass is not a size it is a nickname for matter. Matter is not weight it is what you are, two objects with the same mass can be totally different objects. Mass is calculated on a balance, this is an object that is used to put your mass on one side and a weight on the other side giving you a level bar. Having trouble understanding? Imagine a teetor totter and on one side is a tree, to even it out you must put weights on the other side of the balance to figure out the mass of the object.

Weight is NOT MASS. Weight is pretty much weighed on a scale it is the measure of how many pounds your body is. If you went to the moon your weight would decrease but your mass would not mass never changes.

Any questions? Refer to Mr. Foster, friends, or notes.

Fluids: Weight, Mass, and Volume.

Hello Everyone,

today in class we had a lesson on fluids, and I didn't blog last week because we tested our hover crafts, so I felt it wasn't crucial so I thought I was would do this class instead, but I will still nevertheless do Wednesday's class.

What is mass? Mass is matter, and matter is NOT WEIGHT. If your mass is 80 kgs and you decide to fly to the moon you are still going to be 80 kgs but your weight WILL change.

Mass can never change, 1kg of a substance has the same mass as another 1kg of another substance, even though they may be different, materials, shapes, weight.

There are different ways to hold matter.

Volume= Measurement of Space.

Volume measures how much space an object occupies.

The formula to figure out volume is :

Base X Width X Height

The basic form of measurement for gas is cm3.

Whereas liquids use litres or milliletres.

IF YOU ARE USING VOLUME LIQUIDS you can use cm3.

For more information, refer to Mr. Foster, he did hint a potential quiz, so get ready!

Air flow.

When you drive a car do you notice that there is a fan in the front? This is because without that fan air can successfully move around the vehicle without lifting it off the ground. As you may notice Volvo's do tend to have a higher fan this is because if someone were to fall in the road you wouldn't get caught under the car, not because of the air flow.

Turbulent:

This is somewhat of a crazy air flow, which means there is air flowing in ALL DIRECTIONS. You may notice that when you are in an airplane that it sometimes becomes bumpy, this is because the air surrounding the air craft is going in all directions.

Linear:

The air moves in one steady direction.

Cars tend to have both turbulent and linear wind patterns this means that in general the top layer of air the flies over top the car is linear and that the air flow near the bottom of the car is turbulent.

Any questions about the topics? Then consult your notes, myself, friends, or Mr. Foster. If you are still confused refer to the Internet.

Class- January 6th 2010

Hey everyone,
Today we talked about many things including particles, your science presentations which were due on the 18th, and fluids.

Starting with the science presentations, they will not be counted late until friday so please hand it in. Remember every day after the due date will have 10% taken off of it.

Particles! Today we talked about the particle theory which is below:

1. Matter is made up of tiny particles.
2.These particles are constantly moving.
3.Particles and Matter are held together by a very strong electric force.
4.There are empty spaces between the particles and matter that are very large when compared to the particles themselves.
5.Each substance has unique particles that are different from other particles and substances.
6.Temperature effects the speed of particles. The higher the temperature the higher the speed of the particles.

Remember all pure substances are homogenous.
Imagine a labradoodle (Labrador, and Poodle) this breed of dog would technically speaking be heterogeneous because the animal is made up of two different substances, whereas a purebred golden retriever is homogenous because it is made up of the same substances.

Ok, gold for example is a pure substance because it is built up of the same particles.
Gold in the periodic table is AU, it is easier for most people to remember Amazingly Unique, because those two words might help you remember the term AU, and gold is unique.
