Assignment

Asking a favor of my students. Could you see if the attached file opens in Excel?
 
(I made it in an application called Open Office, because I didn't want to spend extra money on a certain product, and I'd like to see if the file I made can be opened and used by student who have Excel at home.)

Due:

Assignment

FYI: Nothing is due. I'm letting you know I've posted some nice files for an OK review problem. A problem both in circuitry and graph analysis habits in general.
 
This could be folded into circuit review we talked about doing on Friday. The Word file will tell you what this is about. And the Excel should be a fun little thing to use. I tried to make it user-friendly for students.

March 13 Message to Students in All of Mr. Warren's Physics Classes:
 
This message will talk about schoolwork in the next two weeks, but first:
 
Number One Priority until class meetings resume: Your safety and health and your family's safety and health and our responsibility to help avoid the spread of viruses to other people. First and foremost, take all necessary measures to safeguard those things without regard to completing schoolwork.
 
Second, assuming that the above is the case, you will be able to access the work of the physics course you are in via this Assignment Announcement Spot that I've been using for the whole school year. I will be uploading documents with what I hope is a user-friendly, simple, and manageable set of material for the two weeks between March 13 and March 27. The general topics will be:
 
Physics:
I'll post a test you can take by yourself on Chapter 7 and then a rubric so you can grade your own performance.
I'll post material related to the new topic of Charge and the Electric Force. You will want your textbook at home.
 
AP Physics 1:
I'll post a test you can take by yourself on Chapter 7 and then a rubric so you can grade your own performance.
I'll post material related to the new topic of Charge and the Electric Force. You will want your textbook at home.
 
AP Physics 2:
I'll post material for the Completion of Quantum Mechanics. It will include the topics of Blackbody Radiation, The Photoelectric Effect, E=mc2, photon momentum and particle collisions, and nucleus decay processes. You will want your textbook at home.
 
AP Physics C:
I'll post the rest of the E&M Workbook, all units. The plan will be that the only thing considered caught up in these two weeks will be good comprehension of Units IV and V. In a normal school year, it would be Unit IV done now (March 13), Unit V done by March 20, some assessment of Unit V around March 23 and get into magnetism Unit VI a bit before the normal spring break start, March 27. But for what we're doing now, it's totally reasonable to focus on Units IV and V in the time we're gone and be able to "catch up" in magnetism Unit VI right when we see each other again the week of April 6. Let's hope we have class meetings that week. Whatever happens, you are welcome to complete the entire workbook (all eight units) as early as you like, because I'll post all of it. You will want your textbook at home.
 
 
All students:
The easy way to reach me will be at [email protected], and I will be checking email every day.
You may consider me officially available every day to answer questions in an interactive way from 10 AM to 12 Noon. If I ever change the two-hour window, I will announce it on the course Edlio sites. The contact can start by you sending me an email, and then there is a possibility we could shift to phone call to answer your question conveniently. You may contact me outside of the official hours of availability as well.
 
I'll be posting more specific assignments in the separate classes soon. Please let me know if anything above is unclear. I hope to see you all on April 6 and 7.
 
Stay well.

Assignment

Hi Period 5! I miss you all.
 
You might chuckle at the first assignment. It's an optional 10-point assignment: If you can get your home computer or device to run the Photoelectric Effect Simulation from PhET on your device, and if you can take a photo of yourself and that computer screen together in the same shot, email me that photo, and you'll earn automatic 10/10 on that assignment. If that's impossible to do, we'll make it up some other way after class meetings resume. And no two students in the same photo. This is just you at your own home device. The other student has to be in a different home location.
 
You find the PhET simulation here:
 
https://phet.colorado.edu/en/simulation/legacy/photoelectric
 
*Note: if something goes wrong with the virtual circuit site and you're unable to use it, you won't be penalized.
 
Soon after this, I'll make the Photoelectric Effect Assignment 2 and attach it in a separate assignment announcement. There is an attachment now, but it's just a protoype. It needs a bit of work. The reason I attached it is so you could see an image of what the computer screen is supposed to look like.
 
Read Chapter 27 this week as well please.
 
 
Tech help: On my MacBook Pro, I had a hurdle in getting the simulator to run. I had to install Java. I believe this is true on whatever machine one uses. I ended up installing Java by downloading from the following website:

Assignment 2 - Photoelectric Effect
 
Let's give this a try. I'm going to say "due Friday March 20", but please understand these due dates are entirely flexible. I hope you're able to email me so we can stay in contact, assignments or not. I will soon be sending a message about how the Quarter 3 Grades are determined, and there will be flexibility regarding these March 13 through March 27 assignments.
 
So, if possible, I'd like you to email me your response to the attached assignment, Photoelectric Effect Assignment 2. But there will be no penalty if you don't. The idea is to provide assignments so that I can do my job and keep you on track in your effort to understand the concepts in the curriculum. This all presumes that you are healthy and in a position that affords the luxury of doing schoolwork. I hope that studying physics can add some quality to our lives in a challenging set of circumstances.
 
The assignment sheet is attached. Feel free to email me with questions about this or about anything or just to check in. You may text me too. I consider each of these to be work days where I am available to you.

Assignment

This could be a lot of fun.
 
Can you decipher the spreadsheet to solve the mystery of the level changes you saw?
 
Assignment due Monday, March 9: Use numerical calculations to arrive at the best educated guess for which specific three transitions you saw in the lab. There is a way to use the new attached spreadsheet to get clues about how to do this.
 
THE SPREADSHEET HAS BEEN Re-attached. Only use the new version, posted here anew, from now on. It's now more powerful than the one you saw prior to 3:45 PM on Thursday, March 5.
 
The Word attachment is the theory that accompanies this puzzle.
 
This came out really well!

Assignment

Wave Optics Calendar:
 
Wave Optics means looking at light and employing a model that explains phenomena specifically in terms of the things that only waves do - Interference is the prominent behavior in this endeavor.
 
Chapter 24 is central and is to be read as soon as possible.
 
The Diffraction Grating experiment will be repeated on Monday 2/24 and done quickly. Then the light source will be changed to Hydrogen. Labwork related to it will be due Friday.
 
Some kind of test on this topic will happen on Thursday March 5
 
Your IR presentation will be Tuesday March 3.
 
The attached file named Bubble is for the following phenomenon: Why do surfaces of bubbles sometimes present the viewer with colors? It is believed to be an interference effect. But interference requires at least two sources. So why two sources?

HW Due Monday 2/3
 
The attachment almost too thoroughly repeats exactly what I said in class was to be done by 2/3.
 
More importantly, after the three bullet points at the end (which yet again repeats the HW), there is a final paragraph that states how this will connect to the full resolution of the full experiment. So you may work ahead on the full experiment, which brings in the charging time frame.

Assignment

School life’s a lot easier for people who look at what I give them before tests and realize that tests then ask those very same things. Life’s too short and challenging to make school testing complicated. The attachments (which were the free response questions on the final*) were both things that were done before recently. Tests are made to be fun puzzles, the likes of which each person has done before. Leaving the predictable* test items blank is missing out. There are people taking advantage of what I’m talking about. For them, the testing (at least the free response) doesn’t seem to be a big deal, and maybe it can be fun.

Other people treat tests like the items require complicated drawn-out techniques, turning the free response part into something that it’s not rather than the simple game that it is. I can only point out that the reality of the free response is not this way.
 
*I had stated that these two types of questions (quite specifically) would be on the final.
