Here's what is happening in week 10 of CH 221:

  • This is Class Presentations week!
    • This week you will be giving your Class Presentation and submitting your final Class Presentation paper. The details differ depending on which section you are in, so see below for more information. And remember, the Calorimetry lab is due this week as well.
  • Class Presentations for Section 01 and Section H1:
    • The Paper: Details on the requirements for the written paper can be found in the Class Presentations page and in the FAQ.
    • The Presentation: You will be giving a roughly five minute presentation to your class section during recitation (Section 01: Friday, December 2 at 1:10 PM in AC 2501; Section H1: Wednesday, November 30 at 1:10 PM in AC 2501.)
    • We will start promptly so make sure you are there on time. A part of your grade includes full attendance on this day, so be there and don't be late, ok?
    • During your presentation you can use the podium Windows computer in AC 2501 for PowerPoint, Google Slides, etc.-type presentations, or you can just 'chalk talk' your presentation (use the chalk board, or visuals, etc.) Any questions? Let me know!
    • A part of your grade in Section 01 and Section H1 will be completing and turning in the "Class Presentation Reviewer Guide." I will provide the guide before the presentations start (or you can bring one yourself, your call).
    • Your Class Presentation paper will be due at the time of your Class Presentation. Print it before class starts; printing after would invoke a point penalty.
    • The Calorimetry (in class) lab is also due at the time of your Class Presentation.
    • If you have any questions, please let me know!
  • Class Presentations for Section W1:
    • The Paper: Details on the requirements for the written paper can be found in the Class Presentations page and in the FAQ.
    • The Presentation: You will need to submit a recording of yourself giving your Class Presentation. I recommend using YouTube or Vimeo (but if you prefer a different platform, that is ok too)... email me the link to your presentation so I can view it later (no large video files will be accepted, only links.) I do not expect the quality of a Hollywood movie, but I do want to see you talking about the subject you researched in an organized and interesting manner. Try to have your presentation be about five minutes long, and I MUST see YOU presenting (not just a PowerPoint-like voice over, I want to see YOU.)
    • Here is a page with examples of Class Presentations from CH 221.
    • Here is a page showing how you can make your video on a variety of platforms (including YouTube, Zoom, etc.)
    • Your Class Presentation paper and Class Presentation video (link) will be due on Wednesday, November 30 by 11:59 PM via email.
    • The Calorimetry (online) lab is also due on Wednesday, November 30 by 11:59 PM via email.
    • If you have any questions, please let me know!
  • We will not be completing a quiz, lab or problem set this week.
