Today's schedule is DCBA

B Block Criminology - Today we'll look at Burglary along with Break and Enter. Just to note that in 2020, during the early days of the pandemic, although there was a 22 per cent decrease in residential break and enters in Canada between March and June, in the four weeks between March 18 and April 15, compared with the same period the previous year, Vancouver saw a 147 per cent increase in commercial break-and-enters. Residential break-and-enters were up 51 per cent (from CBC Vancouver Commercial break-ins up 147% during COVID-19 crisis)…check out the Vancouver Sun Break and Enter Crime section and from July, last Summer, Police report spike in vehicle break-ins in Courtenay

You'll have one question to answer:

What can you do to reduce the chances of being victimized by a good burglar? - Consider targets (houses, cars AND commercial properties like businesses)

To Help: What makes a good burglar?

Police asks residents to help protect their homes after recent break-and-enters

Lock it up or lose it: Police report spike in vehicle break-ins in Courtenay

We asked 86 burglars how they broke into homes

The strange expertise of burglars

How to be a better burglar

The Mind of a Burglar

FYI: We have a "Lock-Down" drill at 1:40 in class today.

A Block Physical Geography - Today we continue our look at chemical weathering. First, for the first half of class, you'll have time to work on yesterday's questions about slopes, along with physical and chemical weathering. Next we'll focus our attention on karst topography and caves (think Guangxi province in China, Ha Long Bay in Vietnam, and Arecibo in Puerto Rico). If you go to the Geoscape Nanaimo webpage you can find some really good graphic and information about Karst on Vancouver Island (on the left hand panel look at "Our Rock Foundations" and you'll find the subsection on caves and karst).

For work today, you'll need to answer "Identify at least three conditions that are necessary for the formation of karst topography" (p.254 in Geosystems Core Text). For cool pictures of solution cave formations check out The Virtual Cave. Also if you wish to see these features "live" you could travel 40 kilometres south and go to the Horn Lake Caves. We'll watch the Planet Earth Cave episode. This will help you with the questions on chemical weathering, Karst topography and solution cave formation.

Check out the National Geographic article "Cave of the Crystal Giants" which is about Cueva de los Cristales, or Cave of Crystals, a limestone cavern with glittering selenite crystal beams discovered in 2000 nearly a thousand feet below ground in the Naica mine in northern Mexico.
