The End in Google Classroom

The End

Alright gents, this is it - I've been told by Mr. Binnis that you are off the hook and that I shouldn't be posting any more work for you here. I do have one last thing I would like you to do for me - there is a short course evaluation form attached below, please fill it out honestly so I have some ideas for next year (I'm new to this Cambridge world).

Good luck with your future endeavors -- I hope you get to venture off into a world with human interaction again real soon! If you have questions or concerns you know how to reach me!

UV-Visible Light Spectroscopy! in Google Classroom

UV-Visible Light Spectroscopy!

I want to take a week off from Cambridge material this week to introduce you to one of those concepts that I think is important, even if Cambridge doesn't necessarily agree.

UV-Visible spectroscopy is analagous to IR spectroscopy, which we have talked a little bit about in the context of organic chemistry. Spectroscopy is basically just the study of how light interacts with matter - in chemistry this usually means absorbing or emitting particular wavelengths of light. In the case of both UV-Vis and IR spectroscopy we are looking to see which wavelengths of light a particular sample ABSORBS (the difference being UV-Vis is concerned with wavelengths in the 400-700 nm range, while IR is concerned wavelengths longer than 700 nm up to about 1 mm).

Since we cannot SEE atoms and molecules directly with our eyeballs, studying how light interacts with them is one of the most important tools of modern (non-Cambridge) chemistry, which is why I want to introduce you to a simple application of UV-visible spectroscopy.

The link below will take you to a page that will walk you through the process of measuring the amount of dye in a particular sample. The experiment spans several web pages, and almost a of them (unfortunately) require flash. If you have access to a proper (non-chromebook/tablet/phone) computer then use that and we shouldn't have any problems. If you don't have access to a computer that can run flash just leave a comment here and either one of your classmates, or myself, will post some screenshots (or a screencast) of the flash pages so you can get the data and understand the experiment. If you don't post anything here I will assume everything is working fine!

There are two blank graphs posted below - you have the option to keep them as PDF files and edit them directly on Kami and submit them like that OR you can print them out and write on them by hand and submit pictures of your work. The completed graphs and tables contained on the two attached pages are the ONLY thing you need to submit! When it asks you for your name/student number near the end of the assignment you can just put anything - it doesn't matter.

There are a lot of pieces to this assignment so PLEASE READ EACH PAGE CAREFULLY!
If you have any questions let me know in the comments here - that way everyone can see the comments (as you may have the same questions!)

Good luck!

Chemistry MC Quiz 2 in Google Classroom

Chemistry MC Quiz 2

I have tried to make this one a little easier based on the feedback from the last quiz - you have more time (than you would on the real exam) and I haven't included many calculation problems this time. You should still have your data booklet/calculator/scratch paper handy before you begin. This one has a little bit of everything that the last quiz did not.. review first!

Molecular Geometry Practice in Google Classroom

Molecular Geometry Practice

You are going to be using PHET to conduct an investigation into molecular geometry. Based on the results of last week's quiz I think you can all benefit from some geometry review!

https://phet.colorado.edu/en/simulation/molecule-shapes

I will be sending you another quiz next week - same format, but different sections, and I am going to take some of your feedback under consideration to make it a little more manageable. In the meantime I suggest you do a little brushing up! The summaries at the end of each chapter are a very nice way to review what you know!

Multiple Choice Exam #1 in Google Classroom

Multiple Choice Exam #1

I am going to be assigning you exam questions through quizizz every week. You should treat these like an actual exam (they are timed) and if you don't do well, spend some time this week studying that specific material. You may also want to spend some time reviewing everything before you start this exam (most of the material on this particular exam is from the first few chapters)

Marking OChem Review in Google Classroom

Marking OChem Review

Looking at your previous assignment it looks like both groups have more or less finished the entire assignment, with the exception of a few questions. Take one last look at both group's work - double check your answers, leave feedback for one another if necessary. Once you are satisfied with your work I want you to use the mark scheme attached below and mark your assignments. You can divide it up however you want - only mark the questions you answered yourself, have one person mark the first half and the other person mark the second half, have both people go through and each give what they think each question deserves. The point is for you to see where you went wrong, and hopefully understand why! The mark scheme begins on page 14 of the attachment. You can write your scores directly on the assignment in kami, or you can leave a comment here.

When we return from break, I am going to be assigning you each some google quizzes that are going to have real exam questions. I want you to try and treat each one like a real exam - I am going to give you a time limit that you should try to adhere to, answer the questions as best you can without referring to your notes or the internet (or each other). Make sure you take some time over the break to review any chapters you are still feeling a little uncertain about!

IR Spectroscopy! in Google Classroom

IR Spectroscopy!

From the responses you have on the previous assignment, I can tell that a lot of you (except maybe Juan) are still a little uncertain about the questions that involve IR spectra. We never really had a chance to talk about it in class, so I have attached a video here that I would like you to watch. I like this video because it doesn't just explain how to analyze the spectra, it also explains WHY we end up with a spectrum in the first place. Spectroscopy is a SUPER important tool for modern chemistry, and the basic principle is the same, it's just a question of what type of EMR you are using to irradiate your sample. If you can understand the ideas discussed in the video, it will serve you well in the future!

On a related note - as you watch the video I want you to have greenhouse gases in the back of your mind. What is a "greenhouse gas" and what are some examples? Why is Mr. O'Brien asking me about this when I am watching a video on IR spectroscopy? What is IR? Where does it come from? What could it possibly have to do with greenhouse gases?

Leave your thoughts as a comment below.

Fun Friday? in Google Classroom

Fun Friday?

Create a video of you explaining how to name organic compounds. You can do this however you would like... use a whiteboard or sheet of paper, write a song about it, teach your dog - whatever you want as long as you are explaining how to name things! The video doesn't need to be any specific length - long enough for you to explain the material.

When you are finished you can either upload the video here or post a link to where it is. If you like what you have done and are happy with the product, I can ask to have it shared on Victoria's social media accounts...

Review Each Others Work! in Google Classroom

Review Each Others Work!

I have looked over everyone's work and provided a little feedback. The last thing I would like you to do before we move on is look at the document you did NOT help to edit. Half of you were shared into one document, and half of you were shared into the other. The links to both documents are below - find the one that isn't yours, and leave some comments for the people who completed it. Are their answers right? Do you agree with what they have? Any changes you would make? Any suggestions you have? Please leave as much feedback as possible for each other!

Review chapters on Alcohols/Cabonyls

Check out the link below for an explanation of the alcohol problem from class - Juan was pretty correct that the alcohol is oxidized in the presence of NaOH AND iodine - so turn the alcohols into ketones (if possible) and decide if they are methyl ketones or not.
