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.

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.

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.
