Science 9 Period 56:  In the first half we learned about mutations, and how some can cause cells to divide uncontrollably, this is called Cancer.  We read Section 2.5 and took brief notes on these headings:  Definition of Cancer, 2 Categories of Tumours, Causes of Cancer,  Do's and Dont's to avoid getting cancer, 3 ways to treat cancer, What does Metastasis mean?.  Due Friday.

In the second half we measured tree circumferences to determing the carbon content of trees, and the amount of CO2 they are responsible for removing from the air. 

Tuesday, September 17

Science 9 Period 2:  Jesse from "Farm to Table" worked with us today, teaching us about sustainable farms and getting us to consider where our food comes from.

Science 9 P56:  We discussed our sustainable (or not) meals from last day, then learned about Greenhouse Gases (CO2 and Methane are two key ones).  In the last 20 minutes we used an online Carbon footprint application to estimate our family's consumption.  Navigate to https://www.footprintcalculator.org/ to try out the app.  We can see how, by living in such a rich country, we may be using more than our fair share of the Earth's resources.

Chemistry 12:  We learned about reversible reactions today, as well as reaction mechanisms.  Due Thursday is the Mini Review Sections 1.1 to 1.8 and Unit 1 (Hebdon) # 46 - 52.  Lab 18C without a conclusion is due on Friday.  Expect a quiz on Reaction Mechanisms
