Magnetism
Today class was fun, I think . haha just kidding. Well, first thing we did were the corrections for our last test. Afterwards we went over the two worksheets we got yesterday which were the magnetism sheet and the study guide, "24.1 magnets: permanent and temporary". Once we were done those we were given 2 more sheets which were the magnetic fields, the earth's magnetic field and a booklet, 2.3 Ferromagnetism and the Domain Theory of Magnetism. In the booklet, we did questions 1-4 together. If you want them, they should be here somewhere on the front page.
If you do not have any of these sheets yet, you should get them as soon as possible. (=
P.S. Do not forget to ask Ms. Kozoriz for your exam review sheets. This will help you a lot when it comes to your exam!

Gravitational Fields
The day begins with the looking over of the Chapter 5 worksheet. Students were requested to answer one of the 12 questions on the white board.
Chapter 5 Review
1. 0.29 m/s^2
2. 5 kg
3. 22 x 10^
4. 145 N
5. -0.53 m/s^2
*note: During class I was preoccupied with trying to create an account for this blogger and did not notice the answers following question 5 were written on the back end of the classroom. I do not trust my own answers to post it here.
After answering and correcting the Chapter 5 Review, we were given the Electrical Field/Lines booklet and Chapter 21 Study Guide.
That is all.
Next scribe will be chosen in class tomorrow.

Gravitational Fields
Today in class we went over the Falling and Air Resistance sheets that we were given yesterday.
Here are the answers to the Bronco skydives sheet:
Circle the correct answers.
1) Most
2) a,b
3) d,e
4) still downwards
5) c,f
6) c,f
7) c
8) greater
a) a= 10 m/s²=
b) a= 6 m/s²
c) a = 0 m/s²
d) a = -2 m/s²
e) a = -10 m/s²
f) a = 0 m/s²
Here are the answers to the second sheet we were given. It's the sheet with the 7 problems.
1) Air resistance is equal to weight.
2) Air resistance to weight ratio is less for the skydiver.
Increase the surface area to make both terminal speeds equal.
3) Fnet = 25 N
Fnet = 10 N [ down ]
Fnet = 0 N
4) 100 N
5) As a skydiver falls faster and faster through the air, the net force decreases.
Acceleration decreases.
Reason: As she is falling through the air, there is an increase in air resistance.
6) She gains more speed in the first second of fall.
She gains more distance in the ninth second of fall.

Today in class we went over the two sheets ms.k gave to us on friday. One of the sheets answers are below this blog. The other sheet we did on the white boards. You will have to see someone in class for the answers for that sheet. today Ms.K gave us two more worksheets, she asked that they are to be finished for tomorrow's class so we can correct both of them in class. That's all we did today. Oh i forgot question 9 and 10 on the second sheet had to be handed in today. So that's it!!!!!!

gravitational fields
hey everyone!
The Gravitational Field
A field is something that has a magnitude and a direction at every point in space. Gravity is a good example - we know there is an acceleration due to gravity of about 9.8 m/s2 down at every point in the room. Another way of saying this is that the magnitude of the Earth's gravitational field is 9.8 m/s2 down at all points in this room.
Gravitational field: g = F/m
where F is the force of gravity.

hey everyone
in today's class we did a lab on gravitational field. Mrs.K handed back our labs and our assignment on Force-Vector Diagram. Mrs. K didn't go over the assignment that she handed back. But the beginning of the class we did weight and the formula of the weight is f=mg, f=mg+ma and f=mg_ma. my advice to all of you is that if you want to be successful in this world, always to kind and generous to everyone. thank you.

Force Vectors
I'm really sorry for posting late. First of all I came late in the class. I think Mrs.K handed out WORKSHEET: NEWTON’S LAWS OF MOTION and THE PRACTICE: FORCE VECTORS ASSIGNMENT. We went over THE PRACTICE:FORCE VECTORS, it was #1-3 but we omit #2&3. If you didn’t correct THE PRACTICE: FORCE VECTORS please check the slide that Ms. Kozoriz putted up for me. I forget to say that we handed in the FORCE-VECTORS DIAGRAMS it was due today.
I don’t really know if this is our homework, but it looks like

Free-body diagram
hey
at the beginnig of today's class Mrs.K asked us to hand in our labs for thoseof us who didn't finished it yesterday. after that Mrs.K handed out some work sheets on free-body diagrams. Free-body diagram is a diagram that represents an object and all the forces acting on it. and one important thing to always remember is
- draw a sketch of the object completely removed from its physical surroundings. often the force vectors are drawn from a dot at the centre of the object.
- draw vectors representing the force acting on the object.
- do not include forces exerted on the surrounding by the object.
- when finding the net force acting on a object from a free-body diagram, use the rules for the vector addition.
Force of thrust is when a general term for the force that move onjects such as rockets, planes, cars and people.
Force of tension is when the pull exerted by a string rope, or cable are attached to a body and pulled taut.
Force of spring is when a restoring force , that is, the push or pull a spring exert on and object.
Normal Force is the contact force exerted by a surface on an object.
Force of friction is the conact force that acts to oppose sliding motion between surfaces.
don't forget that we have homework and is due tomorrow.

Hey guys,
In today's class we read pages 12-16 and filled in the supporting and counter argument columns on the wave model of light hand-out. We then answered questions 9-12 in The Nature of Light: Part 2 booklet. The answers to these questions and the previous sheet have been uploaded to the blog. Next, we read the information on Young's experiment starting on page 17 to page 20. For the remainder of class we worked on questions 1&2 on the Young's Experiment Problems sheet given to us today. These questions are due tomorrow!
I think I might have screwed up the order in which we did things. I apologize! I have a terrible memory. However, I am positive that this was all we did. Please correct me if I'm wrong.
**Our test on this unit will be on Monday or Tuesday of next week.

Hello!
Today in class we corrected questions 1, 3 and 4 in the seperated question booklet of this unit handed to us last week.
Answers:
(Corrected on the board:)
1. The color would different when it is being reflected because when the speed decreases the wavelength will be less.
3. Plauck's quantum hypothesis suggests that light comes in small bundles of energy called QUANTA. QUANTA is similar to Newton's idea that light consists of small particles.
4. We can learn that we must NOT BELIEVE a theory only on the basis that it comes from a famous person. There MUST be strong supporting evidence.
After correcting the questions, we read pages 8 to 11 and recieved a worksheet based on information you would have to fill out for one of the scientists.
Review:
Scientists and their measurements of speed are..
Galileo (1564 - 1642) 3.4 x 10^3 m/s.
Roemer (1644 - 1710) 2.0 x 10^8 m/s
Fizeau (1819 - 1896) 3.133 00 x 10^8 m/s
Foucault (1819 - 1868) 2.997 96 x 10^8 m/s
Michelson (1852 - 1931) 2.997 29 x 10^8 m/s
Today's Accepted Value 2.997 924 58 x 10^8 m/s
These scientists, beginning with Galileo and his first attempt, used their own methods to observe the speed of light.
The end!

Today in physics we corrected our test from last unit and all the answers should be or are on the blog. Afterward, we were given a worksheet, which was a chart for evaluating the models of light. If you don't have the sheet yet, you should get it right away from Mrs. Kozoriz. So on the sheet we learned the meanings of:
rectilinear propagation: travel in straight lines
reflection: just look into a mirror
refraction: the bending of a particle entering a new medium
dispersion: light is refracted to form colours of the spectrum
diffraction: the bending of a wave around a barrier or through an opening
partial reflection/refraction
And speed of light .. again.
For each of these phenomenon we came up with supporting arguments and counter-arguments. All of this information should be on the blogger as well.
Lastly, we were given the Part 2 Wave and Particle Models of Light Problems booklet. We were assigned to do questions 1, 3 and 4. They shouldn't be that difficult .. i think. And that's pretty much it! :D

Nature of Light Part 2
Today in class we read pages 2 - 7 on our new booklet, called "Nature of Light: Part 2 The Wave and Particle Models of Light" Ms. K gave us a worksheet to work on, about the four theories of Light or something like that. Answers are below, this rather short post of mine.
The next scribe? I don't know, whoever didn't do it yet I guess.
Monday, April 6, 2009
hah! i finally did a blog! =P
OK! so, i finally remembered to do the blog, which is pretty amazing if you ask me =O
anywho, today we went over some questions. i dont know what sheet they were from cause i kinda wasnt paying attention because i was sooooo tired and cranky. But after those questions i paid attention to the graphs we worked on and the fact that we have a test tomorrow, Whooppy!
So for the test you gotta know the whole booklet on nature of light, or something like that. and understand how to find the slope of the graph and the formula used to express it.
I really dont know what else to write, im completely brain dead today due to the lack of sleep.
and i think Anna should scribe for tomorrow...i DO get to pick the next scribe right?

Today in class we started off by finishing our lab worksheets we did on Monday and catching up on any work that we didn't complete. If you missed any classes, please see Ms.K and ask for any work that you missed.
If you were caught up with all the work Ms.K provided us with 3 worksheets. They included a Crossword Puzzle, Graphing Data Study Guide and a Graphing question sheet. Answer these questions by reading in the textbook.
Remember, spring break is coming up soon so dont get to lazy! You should review these worksheets or complete any incompleted work! And ask questions if need. Have an awesome spring breakkkk!

Hey guys!
We started today's class by going over Exercise 1 and Exercise 2 of the Grade 11 Physics: Nature of Light: Part 1 sheet, handed out last friday. Then we briefly looked at pages 8-10 in our Nature of Light booklets before doing a "super-fun" lab; as stated by Ms. K.
We were instructed to determine the diameter and circumference of 5-8 different lids, and then graph the data onto graph paper. We then used our results to answer the required questions. This lab should be completed and ready to hand in tomorrow! (Don't forget to label both axis and give your graph a title.)
There will most likely be a test on this unit after spring break, so make sure that you ask someone for help if don't understand something. How about Friday for the test?????
*Outstanding Concept maps are to be handed in IMMEDIATELY, if Ms.K will still accept them.
Next scribe is: whoever hasn't done it yet.I think Jon wanted to do it.

Hi everyone
Today in class we went over the lab called "The Back Box". it was about guesing what is in the box by rolling it over and over. Mrs K gave as a sheet and we answer it by making observations, Inference(conclution) and diagram about The Black Box lab. We also got a worksheet in class today, which we have to do Exercise 1 & exercise 2 part. Remember "Concept Map" is due 2morrow. So that's all what we did in class 2day.
I think Mrs. K will choose the next scribe post in class.

Graffitti Exercise
In today's class, we had to read from page 1 to 7 in the green booklet "Nature of Light". After that, 3 students were assigned in one group and had to give examples for a the following question on a coloured paper and switch to another group to answer another question in every two minutes. Students switched papers about three times and Mrs. Kozoriz went over to the head board and put all of the answers that was written on the coloured paper. Nearly end of the class we were assigned to do an assignment which will be due on friday called "Concept Map" I hope that you can understand what I'm trying to say.

7. a) v=347m/s
b) v=323m/s
8) d=345m
Those are the answers for the two sheets from Monday's class. You should probably finish the two worksheets the Sub gave us today for tomarrows class because Ms.K will probably go over them.

Resonance
hi everyone.
in today's class we went over the vocabulary review.And also we read the yellow booklet from page 5 to 10. Mrs. K. told us to highlight some of the words because they were important. and tomorrow's class we have a lap if I am not mistaken. remember if you mist today's class checkout the answers for these questions below in the slideshow.
next scribe is Zaiza.

Friday class...!
Hi everyone
I'm really sorry for posting late. First of all i came late in the class. I found students watching video about sound wave which was awesome. It was basically helpful because we learned lots of things that we didn't know before .We learn that at night time the frequency is lower than a day time, that why we hear people whispering from far away at night than a day time. It is one of thing that i was wondering. Later we wrote and handed in 5 to 7 things that we actually remember in the video.
Ms.Kozoriz handed back our tests and went over the answers, checking if anyone had any questions about it. For those of you who did well, congratulations and keep it up. I hope those who didn't do as well, they'll try their best next time!. Ms. Kozoriz putted up for me the answers for the test, but it wouldn't make much sense if you did miss Friday because you won't have your test in front of you. I would suggest getting your test from Ms. K when you can and then just compare your answers with someone in class if you have any questions about it. Ask your Friends or Ms. Kozoriz.
I don't really remember if we have homework, but I thing we'll correct lesson 15 vocabulary tomorrow.

WEDNESDAY CLASS!
In today's class, Ms. Kozoriz gave us a new unit called Sound. We did a lab today about the sheet she gave us about making sound, and answered some questions about it. We did it with groups and predicted how sounds are produced with some of the objects we used like a ruler, a mallet and a tuning fork, and a cylinder with water. We made a sound with a ruler by putting the ruler at the table projecting it beyond the edge of the table and plucking it. We also made a sound to the tuning fork by smashing the mallet into it. Lastly, the cylinder with a water in different levels, by strongly blowing the top portion of the cylinder across it.
One last thing, she told us to read pages 3,4,5, and 6 in the new booklet called sound unit that she gave us in today's class.... So hope you all guys read it and have fun reading it.. :D
So the next scribe will be..... Flash3N

TUESDAY & WEDNESDAY !!!!!
On Tuesday, we corrected a couple of worksheets we got from the previous day. One is called Exercises - Refraction and the other is called Refraction. They both have similar titles but they are different. The answers to Refraction are on the post previous to this one. After correcting the worksheets, Mrs. K assigned us lab work.
TODAY, we just continued on with our lab work and we handed it in at the end of class!
****Please talk to Mrs. K if you missed the lab or any work! I CHOOSE ASHLEY A. TO SCRIBE NEXT!

Thursday's class!
Today, Mrs. K started the day by going over the answers in the worksheet, Waves in Two Dimensions Unit: Reflection & Refraction given the day before, when they watched a video. The answers are posted in the blog, it is titled, "Waves2D". Unfortunately, I wasn't able to watch the video but you can just ask Mrs. K for further knowledge about the answers.
After that, she read some notes in "Waves in Two Dimension" from pages 7 to 9. In page 9, we learned that when the waves move from deep water to shallow water, their speed decreases, therefore, the wavelength of the waves must also decrease just like in our previous studies in "Waves in One Dimension", it stated that when a wave move from a fast medium to a slow medium, the transmitted wave moves slower and the wavelength decreases as well.
The notes, in my opinion, are hard to understand and they move from one topic to another pretty fast, so if you are confused about anything, just ask Mrs. K before tomorrow's class.
After reading the notes, she gave us a review paper about water waves moving from one depth to another, it is called, Water Waves Moving From One Depth to Another. (: and a worksheet, Waves in Two Dimensions - Assignment 1 that was supposed to be handed-in after the class but she said we can hand it in tomorrow and that pretty much covered the second half an hour of the class.
...and the next scribe will be yassin!
Tuesday & Wednesday!
On Tuesday, we received a booklet called Waves in Two Dimensions. We read through the first few pages and learned how to draw the incident and reflected wave rays. We also received two papers: Guideline to Drawing Problems and Waves in Two Dimensions - Assignment 1. For Waves in Two Dimension - Assignment 1, we were asked to do the first two question.
On Wednesday, we got our tests back and corrected them. We also went through the two questions that were assigned the previous day. Afterwards, we watched a video and answered some questions on a handout given by Ms. K.
Oh! And the next scribe will be Jen-Jen!

Thursday & Friday
Thursday:
I was supposed to scribe for Thursday, unfortunately, I was not there. Fellow students told me that we had an assembly, then did a worksheet that I dont know anything about. Please see Ms Kozoriz or anyone in the class for what we did.
Friday:
We had a substitute, she gave us five minutes to review, and we wrote the test. I thought the test was easy.
We were not assigned any homework for the last two days of school before the long weekend. Hope everyone's having a good long weekend so far. See you all on Thursday! (dance people will be performing for the feeder school, both Tuesday and Wednesday, I think.)
The next scribe will be Pamela Gaza.

Wave Interference and Principle of Superposition
So basically we just went over the worksheets that were handed to us yesterday and corrected them. They were about superposition of waves and constructive and deconstructive interference. Here are the answers in case if someone needs to look at it again
Sorry if it is hard to read. As well we did wave problems in the book and did questions 2,5,7,11,12 and 14. The answers to these questions are already posted up on the blog by Ms K. Also, she gave us a Physics: Principles and Problem Crossword puzzle. If you don't have one ask Ms. K.
Right now for me Physics is some what difficult for me but hopeful I will get it.
For Reminders: We have an assembly tomorrow first period in the morning and our physics test will be on Friday.
So the next scribe will be.....Praisia.

Waves
For today's class we begun by watching a video. The video was mainly about things we've already learned.
We then went to correct the work sheet Wave Characteristics. The answers to this work sheet should be on the slides. Since the slides were not posted yet, I'll give the answers. I'll only be posting the final answers since I'm unable to make the full equation.
1 a. 1.65m
1 b. 16.5m
2. 2.9m
3. 9.2 x 10^5 Hz
4. 12m/s
5 a. T = 8s
b. f = 0.125 Hz
c. 16 cm
d. 162m/s
We also corrected the Study Guide sheet and for those who missed the answers here they are:
Wave Interference:
- The speed of a mechanical wave does not depend on the amplitude or the frequency of the wave.
- It only depends on the properties of the medium.
- In a given medium, the speed of a wave with a large amplitude is equal to the speed of a wave with a small amplitude.
- In a a given medium, the speed of a high-frequency wave is equal to the speed of a low-frequency wave.
- When a wave reaches a boundary between one medium and another, the wave that reaches the boundary is called the incident wave.
- The wave that moves through the new medium is called the transmitted wave.
- Some of the energy of the incident wave moves backward from the boundary and is called the reflected wave.
- If the difference between the two media is small, most of the energy of the incident wave will be transmitted.
- If the difference between the two media is great, little of the energy will be transmitted.
- When a wave passes from a more dense to a less dense medium, the reflected wave is erect.
- When a wave is transmitted from one medium to another, the frequency of the wave does not change.
- The speed and the wavelength of the wave do change.
Superposition of Waves:
- When two or more waves move through a medium, each wave affects the medium independently.
- According to the principle of superposition, the displacement of a medium caused by two or more waves is the algebraic sum of the displacements caused by the individual waves.
- Constructive interference occurs when the wave displacements are in the same direction, and results in a wave with a(n) greater displacement.
- After the two pulses have passed each other, they have their original shape and size.
- Destructive interference occurs when the wave displacements are in opposite directions.
- If the amplitudes of the two pulses are equal but opposite, the displacement produced when the pulses meet is 0.
- If the amplitudes are unequal, destructive interference will not be complete.
Standing Waves:
- When two waves meet, a point in the medium that is always undisturbed by the wave is called a node.
- A node is produced by destructive interference.
- When two waves meet, the point int he medium where there is the greatest displacement is called the antinode.
- An antinode is produced by constructive interference.
- If the period of a wave is equal to the time it takes for the wave to travel to a fixed point and back, a(n) standing wave is produced.
- In this wave, the nodes and antinodes are stationary and the wave appears to be standing still.
We were given 2 worksheets to work on. Wave Superposition and Principle of Superposition, we were told Wave Superposition would be handed in. I've uploaded both worksheets onto to the blog.
