Plastics and ocean pollution

Food for thought...

Hot Springs of Japan

We've been talking about the Lithosphere and how we can get energy from it. In some places of the world, geothermal energy is much more prevalent where people get heat from the ground.

Japan is a country on the Pacific ring of fire meaning that it is prone to earthquakes and vulcanism (volcanoes nearby) but it also means that hot magma lies closer to the Earth's surface and this energy can be used for:

• hot baths (spas)
• steam oven
• home heating
• power generation

Below is look at the city of Beppu which is a great spot for taking a bath and seeing hot springs.

The Shale Gas Debate

Shale gas exploration is a hot topic in the Gaspe as companies like Petrolia seek to explore the area for petroleum (hydrocarbons).  Trapped within specific areas of the Earth`s crust, we have things like natural gas and crude oil.  It seems that the shale formations of the Gaspe coast could yield a lot of natural gas.  What is the best course of action? What needs to be considered?

Here`s a funny look at how Quebecers view shale gas.



Here`s something more serious... what is fracking??? This is a report from 16x9 by Global News.



What`s your opinion?

A sneak preview of your boat drag racers!

take a look folks... our track will be a similar length of about 7m of rain gutters filled with water.




And the record holder for the 5m track with a time of 1.5sec.

Now that's fast...

Hi All...  applications of magnets are everywhere and they are being used to make trains go fast...REALLY FAST!

Series & Parallel Circuits - Video to assist assignment

Check out this video and think about the questions that follow. The questions below and a few more now form a review assignment (given on Feb.7, available on our google drive).  For extra tutorial, go to facile learning, we recommend lesson 15 topics #1, 2, 3 for voltage, current and resistance in circuits and #5 for some practice with series circuit calculations. (note: equivalent resistance in a parallel circuit will not be tested but if you're interested, please look!)
 


Part A:Compare Series and Parallel Circuits

                                                                    series circuit                           parallel circuit
1.  How many loops are there?

2.  (a) Brightness of 1 bulb?
     (b) Brightness of 2 bulbs?

3. What happens to the circuit when a bulb blows?

4. What happens to the current when a bulb is added?

Part B: General questions.
5. What is the disadvantage to using parallel circuits?
6. How do you check current (how do you connect an ammeter to the circuit)?
7. How do you check voltage (how do you connect an voltmeter to the circuit)?

The Bell

Hi Applied Science 4,

To help you study, I have burned a copy of the exam video from 2012 to a mac in the library.  It's the mac on the hallway wall with flowers as the desktop background.  Just look for the file on  desktop and click. It should open easily.

The answer key is still on google docs and you should already have your own copy of the 2012 tech part of the exam.

Good luck,
Mr.H
