Organic chem last task

Here is a link to the last task for now. ūüôā This is a google doc, feel free to copy it for yourself and use it as a template for your work.

This task is to write an introduction and method for a lab. I am expecting about 2 hours of work or so. (An hour or so in class, an hour out of class…) (Plus or minus a bit, depending on how excited you get about research).

You will turn it in through The class code is¬†9724897, and the password is Harrison. You were all supposed to have a class to work on this, but Friday’s lesson is taken up by the concert. I’ve made this due on Friday April 3rd. If this is impossible for you, please let me know asap.

Otherwise there is no expectation of any work over the holiday. Relax!

Grade 9 review of Evolution and selection

Your test is on Monday March 16, and you got a review package in class with some practice questions.

Here is another document that might help you structure your review. It gives all the objectives for this unit, and the major lines of inquiry. Check that you can respond to each objective.


Global travel

In pairs or threes, please discuss:

  • how do we travel?
  • Do you consider how long it takes to get somewhere when you decide how you travel?
  • What other factors do you think about when you decide to travel? (this could be to a friend’s house, to the shop, or on vacation, for example).
  • What kinds of information do you need, before you make a decision? Where do you get this information?

THEN go to your blog, and using the ideas from this unit, from your Global Travel worksheet, and from your discussion, write a paragraph that shows the key ideas you have thought about and/or what you have considered about speed and travel in today’s world.

When you are finished, please get a peer in class to comment on your blog post. Useful, thoughtful, constructive commentary please. Show a parent or relative later today or this week, and ask them to comment.

Our NEXT unit is on Human Biology: Muscles, bones and nerves. We will be considering how these systems interact. What do you know about this? WHat would you like to know? Make a list in your notebook to show in class next time.  If you have time, consider the following:

On BrainPop, login through your school gmail, and then go to any of:

  • Human body (all systems go!)
  • Nervous system
  • Muscles
  • Joints
  • Spinal cord

Watch the video, and try the quiz at the end of each one. Send the score to Your Teacher’s Google Account ([email protected])

Spectrometry in Chemistry (topics 11.3, 21)

This is about how we use fancy analytical tools to identify what organic material we might have. You will need to be able to interpret the information from mass spectrometers, H NMR (proton or Hydrogen nuclear magnetic resonance), IR (infrared) spectrometres and to put the  information together to work out what compound is most likely.

Please refer to chapter 11.3 and (for HL) 21. Notes would be useful.

There is a¬†video online here (“Signals from within”) about what we use spectroscopy for, and the principles that make it work.

Here is a slideshow of notes.

This site is where most of the spectra in the slideshow come from. They give detailed explanations for most types of spectra.

Another description of IR with (relatively tricky) problems at the bottom.

HL Organic

This is material in chapter 20 in your text book. We are doing section 20.3, then 20.1 and 2

Here is the slideshow (notes) from class.

Crash course has one video that is somewhat useful, on aromatics (with benzene rings).

Check out Mr Thornley’s videos on organic chem if you would like. (Only isomerism at this point.)

Otherwise this site has good but brief notes.
