Welcome Back

Looking forward to teaching everyone.

Come out and support Dance Squad (see Rowena to stay updated!)

PS Ms Alvares is now Mrs Alvares and our little Quatchi is due in February during the Olympics ;)

Congratulations!

Way to go everyone. I hope the new year brings amazing experiences and cool people into your life.Transitions are always amazing - use the perspective of opportunity rather than demise.

And i have great memories of all of you and expect to hear what's new and improved in your lives; my door is always open.

Have a great summer.

Review Sessions

For Biology 12, let's review, going thru the entire Government PLO (it's in your course outline) on Monday June 15th, 1-3pm and again Tuesday morning, 10-12.

The provincial is Monday June 22, from 1-3pm (bring your texts just before or after the exam).

For Science 10, let's review Chemistry, Tuesday June 16th, 1-3pm in my room, as well as Wednesday June 17th for Physics, but in Room 305 with Mr. Singh, from 1-3.
Then, if anyone has any further questions feel free to drop by Monday June 22nd, from 1-3pm.

Again, Science 10 Provincial Exam, in the Gym, Tuesday June 23, 9-12. Bring Photo Identification and a couple of pencils (bring your text just before or after).

Science 10 reminders

Bring an umbrella, a pen, and even a calculator if you have one.

Meet at the PNE, near gate 9, at the Motor Sport Stadium, for 9:15 AM.
You'll be in groups and required to fill out a worksheet, to hand in at 2PM when we'll be asked to leave the park.

Remember, dial 604-953-3333 for bus information. Or google translink.

Nephrons and Kidney Stones

Kidney's relative size and shape.


Differing areas of mineral and crystal buildup for kidney stone formation.


The three stooges. Each are composed of differing elements and therefore are treated differently. The doctor may ask you to catch one of your kidney stones on the way out - let your imagination ride on that one.


Again, more like medieval weapons than kidney stones.


And you probably wouldn't pee this one out. Sound shock therapy would succumb to going under the knife on this one.

http://kidney.niddk.nih.gov/Kudiseases/pubs/stonesadults/
This website is put together as part of the American National Institute of Diabetes and Digestive and Kidney Diseases and will tell you everything from how they've discovered kidney stones in mummies 7000 years ago, all the way to which foods to avoid to prevent a urinary onslaught of gigantic and painful proportions (think rhubarb, spinach, and even grits!).

Some important dates: Final Exam, in-class, Tuesday June 9th.
Pig Dissection (live, not virtual) Monday and Wednesday, June 1st and 3rd.
Review: One class to ask questions, seek clarification, etc., Friday June 5th.

Biology 12 "Urinary System in a Nutshell"

This is a good, basic introduction of the nephron.


Total and complete description of both structure and function in the nephron. It'll take a few tries but if you nail this video, you've got the majority of our urinary unit. Keyword, few or let's change that to "many" tries.



For the students who want the extra challenge (we teachers like to call these "extensions") I present to you the basis of models we have here in Room 307 :)

This is okay for differentiating between the cortical nephrons (short, within the cortex) and the juxtamedullar nephrons (Juxta/crossing into the medulla) but the juxtaglomerular apparatus contains distal convoluted tubule, not the collecting tubule like she said.




Again, we actually have this model at school if you'd like to practise identifying the nephron's parts. It's a cross-section; the assumption is you know the nephron like a member of your family already. If you don't like your family, you'll have to get re-acquainted.

Science 10
Powerpoint Projects need to be emailed to mistersommerfeld@yahoo.ca.

Your vocabulary is now due - all "words to know" from chap 1-3.

The handout, quiz, and 5 exam questions with answer keys were due today. Find the bins and hand them in to the correct file.

The bibliography is due Wednesday.

Email your powerpoint presentations by Wednesday midnight.

Science 10

Quick reminder; test tomorrow on all of chapter 12.

I'll be checking p 218-221 (workbook) and 506 & 5'18's "Words to know" as well as p. 538, Summary, #1-5.

50 Multiple choice (know your diagrams) and 4 long answer.

Sci 10 and Bi 12

Science 10 - All of 537, 539, and 539 need to get done for the review class on Tuesday, April 14th. See you bright and early Block D :)

http://vancouver.weatherpage.ca/earthquakes.html to see earthquake activity in Canada

Finish up the two Reading checks at the beginning of Chapter 12.2

Biology 12 - finish the "Nervous System - Cram it in baby" worksheet

science 10 biology 12

Science 10: Do Check Your Understanding for chapter 12.1 in your textbook (p 517)
and the workbook, pages 210 - 213 by Monday.

Biology 12: Do you first 15 questions from "Nervous System, cram it in baby" sheet in your booklets.

And enjoy the sunshine :)

Bi12 Nervous System Part 3

Totally Hollywood: glamourous without a lot of substance ;)
-love the sizzle and thunder


More substance here: Sodium's travels during and after an impulse, well done lads
-more sizzle

Bi12 Nervous System Part 2

What happens at the gap? -> Actual fusion of synaptic vesicles with the pre-synaptic membrane; movement of neurotransmitters, to receptors on the other side


after the action potential or electrical signal has traveled down the neuron it needs to get sodium back to the outside against the gradient and potassium inside, also against its concentration gradient
-this requires energy

Bi12 Nervous System Part 1 - Action Potentials

a little confusing at first but good close up of action at the synapse; david suzuki


how sodium (Na+) channels and potassium (K+) channels work together to cause the impulse or action potential to travel like a wave down the axon

Biology 12 Respiration

Respiratory Structure and Function
-general overview of respiration


Mechanics of Breathing
-review of increasing pressure by decreasing the volume of space in lungs
-decrease air pressure by giving the air more room, aka, open up your lungs


Mechanics of Breathing
-intercostal muscles and diaphragm work together to increase or decrease air pressure
-reminder that the thoracic cavity is a fancy term for chest


Oxygen Transport
-movement of oxygen into alveolar capillaries
-98% of the oxygen that makes it into the plasma gets picked up by red blood cells
-2% stays dissolved in the plasma
-red blood cells have hemoglobin (protein molecules)
-hemoglobin has four heme groups, pigments with iron that can bind and release oxygen
-partial pressure of oxygen refers to how much oxygen is in a particular area
-oxygen moves from high partial pressure of oxygen in the blood and moves to surrounding tissue which has, you guessed it, lower partial pressure of oxygen
-omit the saturation graph


Partial Pressures and Respiration
-gases travel from high pressure to lower pressure
-blood oxygen pressures are higher in blood than surrounding tissues and move from the red blood cells to the tissues
-carbon dioxide partial pressures are higher in neighbouring tissues and lower in the blood so CO2 moves into the blood
http://southhill.vsb.bc.ca/Departments/BEST/Biology12/Supplementary/Human_Biology/Respiration/Partial_Pressures_diagram.pdf


Review of Respiratory System-includes great diagram of bronchioles
-reminder of brain's function in detecting oxygen content in blood
-tubes slow passage of air, moisten, and warm it
-diagram of alveoli and mentions its size
-reminder of diffusion of oxygen at alveoli


3D of diaphragm-in case you've never heard of the diaphragm


The Respiratory notes in your handout have since been updated and are viewable on the Southhill website, from Mr Kirkwood, Biology teacher. Thanks Mr. K!
