Today's schedule is DCBA

D & C Blocks Environmental & Social Sciences Today we are off the Courtenay and District Fish
& Game Protective Association facilities for the morning. There will be work from Benton to look at this morning and you may work on your Social Studies questions through the lens of the multiple users of Comox Lake.

Comox Lake supplies the Comox Valley Regional District with its main source
of drinking water. Comox Lake is very large with a surface area of 2100 hectares, a maximum depth of 110 meters in the central basin and a mean depth of 61 meters. The east basin is approximately 35 meters deep at its deepest point. The lake normally stratifies in the summer – that is, the upper layers of water warm up and are kept separate from the lower layers due to a difference in density. The depth of stratification varies by year with the thermocline generally
between 10 and 30 meters. Due to the size of the lake and the snow and glacial melt waters that supply summer flows, the water temperatures in the deep water are generally cold (5 – 6 °C). The upper layers (epilimnion) can get very warm (20.9°C)19. This can increase bacterial and parasite survival rates. So multiple users means multiple lenses/perspectives...hmmm maybe even Environmental Value Systems?

B Block Human Geography - Today we'll look at the Key Question: Why Are Some Human Actions Not Sustainable? We'll look at what a resource is (renewable and non-renewable) along with the uses and misuses of resources by humans. We'll figure out what "sustainability" means (The three pillars - social, environmental and economic) and take a look at the UN Sustainable Development Goals

I'll need you to fill in the chart in your week 2 package on the three pillars of sustainability: environment, economy, and society.

A Block Physical Geography - Today we'll do a brief introduction to topographic maps and I'll show you how to identify location, estimate area, calculate slope, and determine direction on them. We'll look at large versions of the 1:50000 scale topographic maps for the Comox Valley (92F10 and 92F11). For a large copy of the Forbidden Plateau 92F11 map click on the Online - En ligne (PDF or TIFF) at the GEOSCAN Fast-Link site. Using these maps we'll try to make sense of topographic maps in partners.
