To all who visits,

Hello. We have started our new unit in physics which was called Nature of light: Part 1
On monday, we had a sub and he gave us instructions and so we had to read pages 2-8 on the pink handout booklet. Then, we were given some worksheets to work on and these were :

Nature of Light part 1 : exercises 1 and 2
Significant figures
Determining significant digits

I'm pretty sure there are more than 3 worksheets given, but i can't seem to fine the other one.
But moving on, today we corrected the 2 worksheets: significant figures and finding significant digits. Also, we started our lab where we have to gather 8 different circular lids and find its diameter and the circumference. I think this is all we did in class today, there aren't many informations but i hope it'll help you catch up, who ever was away.
(:

the next scribe would be Jabahe. (sorry if i spelled that wrong!)

Sound Test

FRIDAY

On Friday's class we did a test and the test was about the sound unit.
then after the test Ms. K dispersed a sheet that we had to do an experiment
called "MYSTERY BOX". Then she gave us out a new unit sheet " NATURE OF LIGHT"Part:1.
That's all we did in today's class. Have a great and happy weekend.

Tuesday class

On tuesday, we learned about the different frequencies of different notes on a piano. Different notes can be found by ratios such as 4:6:8(in terms of a middle c). We also learned about the different octaves and how they are related to the next octave.

The Sounds of Straws

Good evening my fellow physics classmates! =D Mrs. K started off the class by writing little reminders on the board. She then distributed three sheets. One was entitled "Career of the Month", the other was "Sound Intensity Levels for Various Sources", and the last one was "Decibel Scale". We were given ten minutes to complete "19 Transparency Worksheet" and after the ten minutes elapsed, we went over it and was given the correct answers. She then dispersed two lab sheets entitled "Singing Straws" and "Making a Straw Oboe". There were questions that were supposed to be answered with the lab, but once we discovered what a simple straw can do, we were just so caught up into actually making the sounds and how we could change the sounds. Because of that, no one was able to finish the questions, so, Mrs. K allowed us to submit our papers the next day. That's all folks! =D

REMINDER:
"Singing Straws" and "Making a Straw Oboe" due tomorrow
Don't forget! =)

Next Scribe is... DANA!
His name isn't crossed off the list yet! Scribe twice! XP

Speed of Sound Problems

March 5 2008

We received our tests today on Waves in Two Dimensions that we did last week, and we went over it. We also received our experiment called "Sound and Their Sources" that we did earlier this week. We went over a sound worksheet called uhhh "Sound". For homework we were told to do question 11, 12, 14, and 16 in the yellow booklet. Also for homework we were given a sheet called Grade 11 Physics: Unit 1.3 Sound. We also looked at two Simulations. The first simulation was about the speed of sound through different mediums, and the second simulation was on beats. The two links to the simulation is right below this post.

Next Scribe!

Dana... woopee

Today's class! =)

In today's class, we went over the waves in two dimension test. After that we corrected the four questions that were assigned yesterday.

We also got our lab back.

Then we watched a video about the waves and sound. It turns out that everybody have different sound waves when they talk. The video also showed some of the things that we already learned, like wavelengths, amplitude, transverse waves and etc. It also talked about the sound waves of the tuning fork and how the waves can cancel each other if you use two tuning forks with the same frequency and pitch.

And yes, we do have homework!

Well, that's all we did today! By the way, the answers are posted on the blog =)

Joseph is blogging tomorrow!! =P

Hi everyone :)

So today in class we started a new unit called SOUND, and we got a yellow booklet for the unit.

We did a short Lab called Sound and Their Sources and we finished before class ended so we handed it in.

Make sure to read pages 3-8 on the Sound Booklet and do questions on page 27-28 #4, 5,7 and 17 !

See you all tomorrow morning and no school in the afternoon! :D

The next blogger is..
it's start with a D and ends with aureen !
yeah, it's you DAUREEN :)

Bye everyone :)

Hello again !

Yesterday- Leap Day, we did our Waves in 2D test. I hope everyone did their best.

So.. the next blog is.. Dun dun dunnn..

ROJUANE!

I think it's only fair that I BLOG for Monday, this blog is too short :)

Have a good weekend everyone,
see you all on Monday :D
