I said you'd be going to Edlio to see exactly what you have to do to get good at for the Circuit Unit, Chapter 20. This is why you're here now. The attachment is very important for reasons I explained in class on Tuesday, May 12.

 

Starting Monday May 18, you will be scheduling a time with me to get tested on Circuit solving. It will be small meetings of 1 teacher and 2 students, working in pairs. There will not necessarily be 9 to 10 AM classes on these circuit testing days from May 18 to May 22. I will in the online meeting give you a circuit you've never seen before. You will then explain with your partner to me how you solve for each current. You won't try to use outside references, because I won't give you time to. If you're hesitant or unsure, I'll say, "You're not ready yet, practice more and schedule a later meeting." After predicting the current, you will then build the circuit online on the PhET site (I'll give you power to share your screen with me) and measure the currents properly on the first try. You will earn 100% when your measurement matches your prediction on the first try. This is the simulation version of the Circuit Experiment that I told you about in class. It's a 20 point lab grade. Ideally, these grades will be registered throughout the week of May 18 to May 22. People who have AP tests, just communicate clearly with me, and I'll be flexible in scheduling. But not everyone has AP tests, and for some, there's no reason to wait.

 

Perhaps more importantly for now, the Study Guide. Access it.

 

Arrive at the Class Meeting of Thursday, May 14 armed with the knowledge that these attachments and the assigned task above exists. I will take your solving questions. It's time we follow through on finishing the unit now.

 

And yet another example, as done by me, in the third attachment named "Physics Full Circuit Sample Solution." This isn't to be used until after you did DC Notes Part 4, which are attached elsewhere and are old news.

 

And note, when I say "Zoom doesn't define class," it should be clear that what I mean by that is the substantive content of things like in this posting are the things that define class. YOU define class in how you access and use these resources. An online meeting (as delivered by Zoom or Google or Microsoft products) is your chance to ask me how you're doing on such substantive things.

I strongly recommend you use the following website simulator, because if you use it cleverly, you can use it to check some of your answers before you commit to them:

Electricity Assignment 0 (ungraded). Go to the following website and play with the simulations I listed below:

 

 

Simulations to Play With:

 

Coulomb's Law

Balloons and Static Electricity

Electric Field Hockey

John Travoltage

 

If you are in Period 2, also read all of Chapter 15.

 

And be at the class Zoom meetings Tuesday and Thursday. Period 1 is at 9 AM. Period 2 is at 10 AM.

 

 

Class Meeting On Zoom: Tuesday, March 24 at 9 AM.

 

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.

Updated! This posting used to say what's in quotes below. Get to the part after the quotation.

 

"Before Friday 3/6:

 

Try different numbers in the N and M value cells for the attached data set, and in each case observe what it does to the graph.

 

Once you think the N and the M you chose produce the best line possible, write down the slope of the line that results. The slope will be visible on the graph in the "y = mx + b" format. You don't need to write down the b, just the slope."

 

As of Friday afternoon, March 6. We've moved on. Keep reading.

 

The Attached Word Document is Now Required Knowledge for Tuesday, March 10. If you read the document before 4:15 PM on Friday March 6, you were reading the older version of it. As of Friday March 6 at 4:15 PM, I've now made the document even better. So from now on, only use the updated better one. A good way to tell the difference between the better new one and the older pretty good one is that the better new one is 5 pages and the older pretty good one was 4 pages.

 

The attached Word Document is the final word on Chapter 7. I tell a story in it - How the mass of the sun was determined. Starting Friday March 6 and after Friday March 6, it will be content that's required in the course, and a test will be linked to it somehow. I'm not grading anyone's understanding of it on Tuesday, March 10, but I still expect people to read it by then to stay caught up.
