Today's schedule is ABCD 

A Block Criminology - Bloggin' time! We're in the Learning Commons/Library today working on our online activities. Last week I asked you to come up with your own theory about why crime happens and today I'll ask you to create another entry on crime trends, specifically youth crime and school. Now that you know about trends in crime and what violence is in relation to age, gender and class, try to answer the following:

Do you think that school is one of the most dangerous places for young people in society today?

Broaden your scope a little and do not necessarily focus on Vanier for this question. Think about other Canadian, British Columbian or Comox Valley high schools and generalize your response a bit. Don't forget that you'll need to find a story to back up your point of view here (either one about how little crime exists in schools or one that demonstrates that schools are somewhat dangerous places).

RCMP: School Violence
Stats Can Youth Offending in Canada

More than 1 in 7 girls say they were sexually assaulted by another student 

'They're not taking it seriously': Under-reporting of student violence persists

'I thought he was dead': CBC survey reveals 4 in 10 boys are physically assaulted at school

Youth Crime In Canada which states:

• In 2006, 1 in 10 youth crimes were committed on school property
• Crimes at school include bullying and violence
• Assaults are particularly common representing about 30% of all violations committed by youth on school property. Uttering threats constituted another 8%
• Nearly 20% of crimes committed at school were drug offences, whereas 5% of youth crimes committed elsewhere were drug-related. Youth drug offences taking place on school grounds usually involved the possession (78%) or trafficking of cannabis (10%)

B Block Physical Geography - Today we'll start with work on igneous rocks and plutonic features...there will be three questions to work on (12, 13, &14 from page 366 in your Geosystems textbook). Don't forget that Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass. These rocks include andesite, basalt, dacite, obsidian, pumice, rhyolite, and scoria. 

When answering q.14 on felsic (>69% silica) and mafic (45-52% silica) rock from p.366 please consider Melting Points, Colour, Density, and Minerals (coarse/fine and type)…SPOILER ALERT, this will be connected to tectonic boundaries and types of volcanoes and their eruptions

Before we do that let's see what Bill Nye has to tell us about Rocks and Soil...Bill?

Next, we will focus on sedimentary and metamorphic rocks. We'll collectively define compaction, cementation, recrystallization, clastic sedimentary rock, and non clastic/chemical sedimentary rock. We will define contact, regional, and dynamic metamorphosism and you'll have question 15 from page 366 in your Geosystems text to finish as well.

C & D Blocks Social and Environmental Sciences - The Colorado River Basin covers an area of over 252,000 square miles (652,677 square kilometers), travelling 1,450-miles (2334 km) from source to mouth. The river supplies water to over 40 million people and irrigates nearly 5.5 million acres of farm land. Twenty two federally recognized tribes (indigenous nations), seven National Wildlife Refuges, eleven National Parks, and four National Recreation Areas also rely on the Colorado River. In addition to this more than 4,200 megawatts of electricity is generated on the river. It created the Grand Canyon (one of the Eight Natural Wonders of the World and a UNESCO World Heritage Site) and is an economic driver of the American southwest:

1. The Colorado River supports $1.4 trillion in annual economic activity and 16 million jobs in California, Arizona, Nevada, Utah, Colorado, New Mexico and Wyoming - that’s equivalent to about 1/12 of the total U.S. domestic product, meaning the Colorado River’s contribution is important to the national economy as well
2. For each of these western states, the river accounts for at least half of its gross economic product. The total is much higher for some state economies, including 65% in New Mexico and 87% in Nevada. 
3. If just 10% of the river’s water were unavailable for people, we would see a loss of $143 billion in economic activity and 1.6 million jobs in just one year.
4. The resulting economic hit would be delivered across the board, with the largest effects in real estate, healthcare and social services, retail, technical services and finance.

As famous as the Colorado may be, it’s equally infamous for the stresses placed upon it due to over-allocation, overuse, and more than a century of manipulation. The Colorado River Water Compact drafted in 1922 to divide water between upper and lower basin states was based on analysis of one of the wettest 10-year periods in history, establishing a permanent deficit. The battery of threats facing the natural masterpiece the river has carved through the Grand Canyon have earned that segment the number one spot on American Rivers’ Most Endangered Rivers report in 2015. About two-thirds of the water flowing in the Colorado River and its tributaries is used for irrigation, and the other one-third supplies urban areas, evaporates into the atmosphere, or provides water to riparian (streamside) vegetation. Without Colorado River water, the region would support few crops, and major cities such as Las Vegas, Nevada, and Phoenix, Arizona, would not have grown so rapidly.
