End of year survey

Please take some time to thoughtfully reply to the end of the year survey. This will provide feedback that should help me improve the course next year. Thank you.

End of year survey

Wednesday, April 6, 2016

During this time we will also be reviewing as many previous IB SL topics as possible to prepare for the final and for external testing students May 12-13 exams. The final exam internally will be on Friday May 27 (multiple choice and short answer comprehensive). This is for all IB year two Chemistry students. Please use your IB study guide as a primary source of review. There are topic review questions at the end of each chapter. And use the videos online for quick review as well. I suggest these Thornley videos in particular, which are on common errors students have made on past IB exams. Another useful channel is MSJ YouTube

Option C: Energy

This unit is on option C: Energy. Topics include energy sources, fossil fuels, nuclear and solar energy and the environmental impacts of current energy consumption. Students will present on an energy topic in groups. This is the last major unit of IB SL chemistry. The next unit will be a comprehensive review for internal and external IB final exam assessment. Testing students will exam externally at the Fred Meyer conference center behind Powell park on May 12th and 13th this year.

Ideas for next year's unit...

The scientific consensus on climate change is "that climate is changing and that these changes are in large part caused by human activities,"^[60] and it "is largely irreversible."^[61]

“Science has made enormous inroads in understanding climate change and its causes, and is beginning to help develop a strong understanding of current and potential impacts that will affect people today and in coming decades. This understanding is crucial because it allows decision makers to place climate change in the context of other large challenges facing the nation and the world. There are still some uncertainties, and there always will be in understanding a complex system like Earth’s climate. Nevertheless, there is a strong, credible body of evidence, based on multiple lines of research, documenting that climate is changing and that these changes are in large part caused by human activities. While much remains to be learned, the core phenomenon, scientific questions, and hypotheses have been examined thoroughly and have stood firm in the face of serious scientific debate and careful evaluation of alternative explanations.”

Organic Unit 2

Organic Chemistry is amazing, awesome, interesting, complicated and the stuff of life. Organic chemistry is usually taught as an entire second year college course. We will focus on basic molecular structure, nomenclature and reaction mechanisms. We will make soap, flavors and odors, slime, super balls and other polymers. We will do a short periodic trends and bonding review first, and then go into the actual IB SL Organic content.
