3 Chem/Phys: Juniors, How Have You Been????

HAPPY MONDAY,  everyone!!

First things first - how is everyone? How are your families? 

You know how I put an emphasis on not only your physical health, but social, emotional and mental healths, as well. We are entering week 3 of isolation, distance learning, and being away from each other, your friends, classmates (i.e. learning team members), and everything else at school. Small changes can be difficult, but this has been a BIG change in our lives and routines.

If you are feeling lonely, anxious by the 24/7 news coverage and chatter about COVID-19, bored, depressed, stressed, or anything else, know that this is normal under these circumstances. And also know that we all have many resources to turn to if we need help, or just someone to talk to: counselors, social workers and psychologists are all available through the school. 

Housekeeping items

• Keep checking in with the school each day this week
• While these three weeks have been 'Act of God' days with the state, and no grades have been given to anything you've done in classes, hopefully you have been trying the work to still best learn the content as best you can. STARTING TUESDAY, we have been told that we are back to more normal school, and will begin to issue formal grades for 4th quarter. In the coming weeks we will find out details about semester exams and quarter/semester grades. Official attendance also begins Tuesday - this will be done solely through an email link you will receive daily, and that is all teachers are allowed to use. We CANNOT mark you present if you do not check in with the school, even if we see you on a Zoom session!!  
• AP Exams will be given in May. They will be 45 minutes, free response, and on material up to March in your AP classes. We do not yet know the logistics - should get this April 3.
• Try to keep up as best you can, and we all know this is a challenge because we are mostly on our own. Keep group chats going, call each other, do your own Zoom/Skype/other study groups, make use of video and other online resources, make use of your textbook, email me any time with questions/concerns/deep thoughts/the meaning of life/etc...
• We have a Google Sheet set up for us to share suggested things to try while in our quarantine. New games, videos, links, recipes, whatever! Also, a separate sheet is set up for anyone to ask questions about material, and anyone can help out with responses. This may be useful if you should be trying or thinking about something outside of a class session. 
• If you ever are bored or curious or motivated to try any sort of project, don't forget to chat with me and there are all sorts of things you could try! Refer to the past email I sent, or check out an activities options page on the blog.

3 Chem/Phys

Hope your last unit of Chemistry went well! We will pick up with rotational motion, and complete it with angular momentum the next few days. 

Here's the meeting schedule given to us from the administration, as of today: 

We will offer a couple Zoom sessions each week, at 11 am Monday and 1:15 pm Wednesday. The links to the sessions will be emailed to the group each day. We are NOT allowed to video class sessions. We do have the individual topic videos on the blog, with nearly all topics we covered throughout the year. You can watch the videos before and/or after live class sessions. There will be one official 45-minute office hour for Science classes, at 10 am Friday. These are the only official times we have to meet as a class. I check emails constantly throughout the day and will be available just about any time, every day, if you have questions. 

The other main online resource is our class site on the school web page. Our unit folders are there, the past quizzam solutions, review sets, and so on can be found for anything we've done this year. Check out the solutions to the last rotations quizzam. On the 3 Chem/Phys page, there are already review sets for the AP exam, and the solutions. There is the AP Exam page, with problems going back to the 1970s, and all the solutions in its own folder. 

Unit Packet

Angular Momentum Packet

Relevant videos for Angular Momentum

- If you need to review the rotations basics: our chart of linear vs rotational

- Introduction and examples of the 2 ways to find and use angular momentum

- Conservation of angular momentum examples

- Conservation of angular momentum for ballistic pendulum 

- Conservation of BOTH linear and angular momentum (hit a pencil on a table, and get both types of motion)
- This is the Mechanical Universe video on Angular Momentum I showed on Zoom; start around the 13:20 mark

- Supplemental: Case where there is a non-constant torque, and non-constant angular acceleration
- Supplemental: Using Kepler's and Newton's laws to navigate in space - going to other planets
- a PowerPoint on Angular Momentum found by Sofia...might be useful for some!

Practice Problems
Try to have the Ch 10 problems for Wednesday's 1:15 pm class session, so we can take questions and check setups. 

- Ch. 10 #37,39,41,42,95  on page 3 of packet

Try to have the 2005 and 1998 AP problems by Friday morning's office hours at 10 am, so we can take questions and check setups.

- We will use most of the AP problems as examples during our sessions; recommended to try some of these old APs on your own or with a virtual group. These are:
