Global patterns for Biomes

On Friday we reviewed global patterns for biome distribution.  We put biomes in order according to
biodiversity:  the most to the least
latitude:  from the equator to the arctic circle
elevation:  from sea level to mountain top
ocean proximity:  from the coast to in-land
These patterns underscored the importance of temperature and precipitation for biome characteristics

next, we defined niche, habitat, structural adaptations and population dynamics of predator/prey.  Finally, we observed a video of predator instincts in a feline carnivore here.

THERE IS A small QUIZ NEXT PERIOD on 1.1 and part of 1.2  practice the questions provided in the ecology study file from the previous post.

Please note that the quiz will be on 1.1 and only the specific 1.2 concepts covered in class (1.2: niche, habitat, structural adaptations and population dynamics of predator/prey, not the other parts of 1.2).

One more class - worksheet, dry ice, hand in project

Hello Trek Students.  It was good to see class 2 today. next period is final class.

For our final class, I will accept the following assignments for term marks:

1.  a worksheet done in class
2.  study notes for a chapter of your choice (for class 2, at their request)

optional assignments, no penalty if you do not hand it in, credit if you do:

1.  a board game or computer game:  can be a group project.  some of you have handed this in electronically or as a completed project.  the ones I have seen so far are very well done.
2.  completed corrections for your geology re-test.
3.  one person has requested a thermal energy test.
4.  your participation and notes from working with carbon dioxide (yes, dry ice, I'll get some).

I will be briefly at a PW garden meeting after school on Thursday (tree pruner will be there to give us instructions for pruning our apple trees)  but will be available afterwards at 3:45 pm in my classroom if anyone has questions.  Your science exam is next wednesday.

I will be available to go over any concepts at the following times, for those who would like further instruction:

Thursday afterschool 3.45:  weather systems:  corialis effect, el nino, la nina
Weekend: email me your questions and I will be checking email every couple of hours and will answer your questions.
Monday noon and/or class time and afterschool:  ecology and biomes
Tuesday noon and/or class time:  geology and after school, climate change, cause and effects

Please contact me if you require anything and do use the online resources, notes, study packages, sample exam questions, or to clarify a concept.

Good Luck

Hi class,

The board game is an optional assignment.
You WILL earn marks if you hand in the game by Thursday.  The Geo retest is on Tuesday.  Participation marks were entered for those who attended the UBC field trip lab.  The assignment will also be inputed at a later time.  If you have not handed in your assignment, you need to do so as soon as possible.

Any assignments taken in by Ms. Cheung will be inputed too.

I sincerely regret the inconvenience and confusion that my illness has caused for the class.  Please email me if you have any questions.
