Ears and Sound Waves Notes

- Ears help the brain collect and process sounds.
- Sounds are created by waves of vibrations that are carried
through the air and through other objects.
- The properties of waves include the following:
- amplitude (height)
- wavelength (distance between the peaks/crests
of each wave.
- Sounds become louder as the amplitude of a wave becomes higher.
- Frequency is the number of wavelengths in a given amount
of time and is measured in hertz.
- A hertz is a unit of sound, equal to a wave cycle from crest
to crest.
- The greater the number of wavelengths that pass in a unit of time, the more high pitched the sound.
- infrasound less than 20 Hz is a range of sound waves below the audible span for human hearing. Elephants can hear in these ranges! (these notes are based on that website information)

Study Questions for Quiz

1. What does Hz stand for?

2. What does Hertz mean?

3. Can elephants hear at lower frequencies than humans?

4. What is the difference between ultrasound and infrasound?

5. What is the difference between amplitude and wavelength?

6. How do atoms transport sound through air?

Olympic Theme Song

I think I'm addicted to watching the olympics... The opening ceremony was amazing. My husband was especially excited when W.O.MItchell's work was quoted for the "prairie excerpt" during the ceremony... However I think my favourite part was... the whales and the amazing poet from the NWT's. I need to get a copy of that poem!

To check out "I Believe" copy paste the following URL into the window:

Try out the following video games on-line.


This game shows what it would like to live in a country that does not respect human rights and why some people become refugees. This game was created by the United Nations High Commission with the purpose of teaching students about human rights and the lives that refugees live.


Darfur is a western region of Sudan (in Africa). People everyday endure unimaginable atrocities. This video game reflects a small fraction of what it's like to survive in this region. The video is school appropriate, which means it was created to give students a chance to learn about life in this country. It is not violent nor does it treat the sensitive nature of this issue in way to "sell" video games. This game is sponsored by MTV and the Human Rights Foundation.

This game is sponsored by CIDA and I have yet to play it. It was designed for students... I'll let you know how it goes. It really took a long time to load, perhaps I was just too far away from my wireless connection hub. The cartoon at the beginning was pretty vivid.

As you play these games, think about the deeper meaning. The actual event that would be happening. Be sensitive to the fact that although it's a video game, the events were based on real people's lives. Play, have fun, but think and reflect too!

Social Studies - Looking at the World and Wealth Distribution


How do we spend our money? How do we use our resources??
How does sustainability connect with economy? Why is it something that we should think about when we think of our future??
Is the way wealth is distributed around the world fair??
Who are the richest countries? Who are the poorest countries??
What is a fair trade product? How do fair trade products help to evenly distribute wealth in the world?
What does it mean to be a responsible consumer? What do responsible consumers do?
What are the advantages and disadvantages of buying locally produced goods; buying fair-trade products; and buying mass produced products?
Who "wins" or gets the best deal in each of the above situations??
How can we measure wealth? If you are wealthy, are you happier than those who are poor??


THE STORY OF STUFF VIDEO - Interesting video which connects to the questions above...

VIDEO - DO I NEED IT? A cute song written in reaction to "The Story of Stuff". The tune will probably never make the radio waves, but the message is excellent... Just listen to the message...

I couldn't help but feel a bit guilty about shopping as I watched the above video... Hmmm... something to think about....



Please make sure you hand in your DISASTER IN HAITI ESSAY before 1st recess on MONDAY, FEBRUARY 8.
This essay will be part of not only a Social Studies mark, but also some of the content will be evaluated for Science (Earthquake information - "Exactly what happened in terms of the earthquake, plate tectonics, etc. in Haiti?")

Ensure you hand in all drafts, outline, web and jotnotes with your essay as well as the rubric. Please staple your essay requirements with the good copy on top with the rubric attached. All late assignments will be deducted 5% / day, as explained in the Social Studies Expectations and Procedures at the beginning of the year.

I look forward to reading your essays! Really!!
Ms. S-M :-)



Coldplay just happens to be a band I really like... and check it out... they are trying to do their part and make a difference and help those in need!!

Disaster in Haiti Essays

This is a reminder that your Haiti essay must be handed in on Monday, February 8 before 1st recess or there will be late marks (5%/day) deducted from your mark. *** REMEMBER to hand in all drafts, outlines, webs and jot notes for your essay. Remember to reference all handouts from class, as well as the rubric before you hand it in. This essay will be primarily a Social Studies mark, however one aspect on earthquakes will be used for Science. Again, refer to the assignment handouts and evaluation rubric for more information.

ESSAY EXPECTATIONS... Make sure you have an introduction with attention getting lead, topic sentence (what the essay is about) and thesis statement (what topics will be explored in the essay - see examples on handouts given in class); at least 3 body paragraphs (one must explain scientific information on plate tectonics, the other 2 on life in Haiti before the earthquake and life after the earthquake) and finally how can Canadians help... or how can we help; and finally a conclusion paragraph that restates what topics were explored in the essay, plus wraps up the essay and leaves the reader thinking.

Make sure you follow the format above for the 5 paragraph essay and include the expected research for the questions that were given in class.
