Welcome Back

Welcome back to class grade 10s! Now that you're all warm and dry again, we can start to figure out why we were so wet out on trip!
A huge low pressure system (high kinetic energy, less dense and high moisture air) was sitting off the coast and moving inland.  And what came with it was loads of precipitation!  Understanding how air masses move and interact is the key to figuring out weather patterns, and also understanding the forecasts we hear on the news!

HOMEWORK
For next class I would like you to complete your drawing of the three fronts (Warm, Cold and Occluded).  Please include:

• labels on the picture
• description of how they interact
• characteristics of the weather each front generates

Also... we will have a test on Chapters 10 and 11 on Wednesday October 8th (block 3) or on Thursday October 9th (block B).  We will spend this week looking at chapter 11 and I'll set you up with some review and summary sheets!

Please work through the following review questions in the text -to be handed in before your test:
Pages 460 in text -questions: 2,3,4,12,13,18

Notes from Chapter 10 can be found HERE, though you should have all the pictures in your own notes already.

Northern Lights in Vancouver

It looks like you don't necessarily have to go to the Yukon to see the northern lights!  Tonight and tomorrow they could be visible in and around Vancouver (if you find a dark enough spot to view the sky)!
A fast moving cloud of charged particles -resulting from a solar flare is heading towards the earth, and as those charged particles collide with particles in the thermosphere, the result is bright green, yellow and reds in the night sky.

So, set your alarms and find a dark view of the sky!  Check out THIS SITE to see approximate times for viewing!

If you get any pictures -send them to me and we can post them!

What's the weather?

Its a precarious balance... we have just the right amount of oxygen, just the right amount of carbon and just the right temperature to make life here on earth not only comfortable, but also possible!

Review the notes on the LEVELS OF THE ATMOSPHERE and the huge and very detailed document on Chapter 10.2.

Science 10-2 (block 3)
For next class, please read/review/make notes on pages 9-39 in the Chapter 10.2 document.  We looked at the first part in class today.  We will discuss the concepts in these pages, but we'll move fast so we can explore some of the implications of these ideas!

Energy all around us

A poem by Camryn Sykes, Candace Sykes, Leiah Kirsh, Jackie Molnar, Jessica Ham, Pia McNab, and Tiffany Liu

Wind blowing,

flowers growing.

Leaves dropping,

bunnies hopping.

People smiling,

leaves dying.

Birds chirping,

Camryn burping.

Human running,

Jackie being cunning.

Planting seeds,

removing weeds.

Biking child,

canines gone wild.

Shinning sun,

worms having fun.

Barbecuing a steak,

the chef tries to bake.

Pollinating bees,

growing hemlock trees.

Energy Transfers all around us

Conduction, Convection and Radiation are how energy is transferred all around us.  We often feel this transfer as "Heat" and notice the temperature difference.  Remember energy flows from areas of High kinetic energy (high temperature) to areas of Low kinetic energy (low temperature) -just like when you're camping and you forgot your sleeping pad... your heat is transferred to the ground and you are left feeling cold!

YOUR ASSIGNMENT due next class (Sci10-02 Wednesday, Sci10-04 Thursday) is to think of, and write down two unique examples for each form of energy transfer.  Be specific and explain WHY your example represents either conduction, convection or radiation

Energy is Everywhere

It was a beautiful day to enjoy the sun today, so that is exactly what we did.  And along with the enjoyment of the sun, we got to see and feel all the energy around us and we started to explore what all this energy means, and how it is transferred.

You can find our PPT notes HERE, and we will finish up with it next class.

 

Welcome Back!

Welcome back to school and into grade 10!  Its bound to be a fun year full of more than we have time for I'm sure!  To keep us all up to date and on the same page, please visit this blog regularly, especially if you have been absent.  Here you will find information about what we have done in class, what we will be doing, and links to cool sites, articles, videos and of course handouts and assignments.  Feel free to send me cool stuff you find (youtube videos? articles? pictures?) and I will share it with our community.

Science 10 is a pretty full course, and there is lots of stuff that will blow your mind throughout the year.  I hope you have as much fun with it as I do!
