Today's schedule is BADC

B Block Human Geography -Today we're back in the library looking at the 2018 World Population Data (using both the PRB Interactive Map and the pdf data sheet) to see current trends and numbers in world population. You have a webquest with questions in your week 3 work package to answer. You may work with a partner to find answers to the 17 questions but you all need to record answers. Use:

2018 World Population Data Map
2018 World Population Datasheet

Population Reference Bureau

Please note that the map is 2019 data and the data sheet is 2018 data.

For the last question you'll need to choose one of the following demographic variables using the World Population Data Sheet and create a choropleth map showing the distribution of that indicator on a world outline map. The PRB World Population Data map is an example of a Choropleth Map. Use it to help you create yours, just select the indicator you wish to create and it will make a choropleth map that you can recreate.

Infant Mortality
Birth Rate
Death Rate
Total Fertility Rate
Life Expectancy

The instructions are in the week 3 package but feel free to ask me in class today. Good luck!

A Block Physical Geography - Yesterday we looked at magma, igneous rocks, and plutonic (intrusive) igneous rock features (both concordant and discordant features). Today we will focus on sedimentary and metamorphic rocks. We'll take down a cross section diagram of the geology here in south western British Columbia. We'll collectively define compaction, cementation, recrystallization, clastic sedimentary rock, and non clastic sedimentary rock. We will define contact, regional, and dynamic metamorphosism and you'll have question 15 from page 366 in your Geosystems text for homework.

Check out the Dynamic Earth Interactive Rock Identification site here
Check out the Rock Cycle/Type animation from the BBC
Check out the Flash animation of Metamorphic Rock Creation here.
Check out the Rock Cycle Interactive from Prentice Hall here
Check out CK-12 Sedimentary Rock or Metamorphic rock information.

D & C Blocks Environmental & Social Sciences - All Benton today, which means you're down to the Tsolum for a river study. You'll look at some important characteristics of a river and do a review of local hydrographs. On the field study, you'll be measuring flow and volume, freshwater invertebrate identification as indicators of water quality, with a summative report to be completed.

The quantity of water passing by a point on the stream bank in a given interval of time is the stream’s discharge. A stream’s discharge may vary because of changes in precipitation or the melting of
winter snow cover. In response to varying discharge and load, the channel continuously adjusts its shape (and location). Discharge (expressed in cubic meters per second m3/s ) is a factor of width, depth for a specific cross section of the channel and velocity  (Q=wxdxv). A hydrograph helps to measure discharge. Here is the provisional hydrometric data graph for the Tsolum River (near Courtenay) from September 13th to the 20th (08HB011) Compare that to the Fraser River at Hope (08MF005). Notice any differences?
