I’m aware that many of you were affected by power outages yesterday, so I’ve changed the due date to tonight at 9 PM for the Week 13 physics homework – John

• Chemistry: McMurray & Fay 10.1 – 10.5; 8.1 – 8.6
• Math: Stewart 4.6, 4.5
  • Math Reading Responses due via WebAssign 3pm Sun. Jan 28
• Physics: Wolfson 22.1 – 22.4; 23.1 – 23.4
  • Physics Reading Response due via MasteringPhysics 6pm Sun. Jan. 28

• Reminder: Poster Tour Write-ups are due 1pm Tue. Jan. 30. See Energy Project page for details.

Though there was no physics quiz this week, there will still be an IDEAl solution problem due next Wednesday, Jan. 31, based on Chapter 8 material. This is Problem 7 from the Week 12 Mastering Physics assignment. This should look a lot easier after working Chapter 20 problems!

As a reminder, Chemistry students will be working with their groups to make two soaps and one detergent. 

The oils we have available for soap making are as follows:

• Coconut
• Avocado
• Olive
• Almond
• Corn
• Grapeseed
• Vegetable
• Walnut
• Sesame

Please consult with your group and pick two oils to use before coming to lab next Tuesday.

As a reminder, we will be doing a workshop on reading scientific papers on Thursday during our normal chemistry slot (9-11 am).

Choose one of the peer-reviewed sources you found for your project and bring a printed copy to the workshop. If possible, make sure the paper you choose is an original research article rather than a review article.

It is a good idea to bring writing implements that will help you annotate in different colors (highlighters, gel pens in different colors, colored pencils). 

I have had some questions on the format for the “mini-poster” reports for Rocket Lab. Perhaps the best way to explain your task is this:

Imagine that you are presenting your results from the Rocket Lab at Science Carnival (or  similar event). Your “poster” will be presented on a tri-fold board of the sort you might have used for your elementary school science fair. However, you are not allowed to access the tri-fold board until two minutes before the event starts. Therefore, you must have all of the information for your poster printed out on regular 8.5″ x 11″ paper before you show up at the event, so you can just tape it on the tri-fold board when you arrive.

Create the four pages described in your lab manual. These are the *only* pages you get to attach to your tri-fold board so they must be self-contained.

I realize that the poster tour assignment isn’t due until next week, and you haven’t had formal instruction in how to create a poster yet. Draw on what you have seen in posters around the Lab buildings as well as the principles we covered when we talked about Powerpoint presentations last quarter. The point of this assignment is to get you thinking (and discussing with others) the best way to present all pertinent information! (Note to perfectionists: you will have another chance to do a mini-poster for experiment 11 so this is not your only chance to get things right.)

• Please find problem set assignment at the Math page, also linked in the main navigation bar.
• Complete All Problems in your Math Problem Set Notebook. Bold underline problems also due via WebAssign by 9pm on Fri. Jan. 26, 2018.
• A reminder that the problems chosen for submission via WebAssign are not necessarily the most important or the most interesting on the problem set; sometimes those are just the problems which are available on WebAssign.

A few items that we forgot to announce during our weekly wrap:

1. There will be NO quizzes in any subjects next week.
2. Please bring your energy bill to class on Monday as we will be discussing them during the normal Math quiz time.
3. There is no Chemistry homework due on Monday.
4. A reminder that your Energy Project Proposals are due 9am Monday January 22.

Physics quiz corrections and the first Winter IDEAl solution are both due next Wednesday, Jan. 31.

For quiz corrections, please use the fresh, slightly revised copy of the quiz posted here.

The problem for the IDEAl solution is based on the 3rd quiz question but with one small addition. To get a sense of whether your answer to the new part is reasonable, you might compare with this video of a system based on the same principles at work on the International Space Station (fast forward to 1:45 if you want to skip to seeing it in action).

For a refresher on what my rationale and expectations for the assignment are, please review the post from Fall quarter where I explain both.
