First, I'd like to thank my friend and colleague, Dean Baird, for inviting me to be a guest blogger here at The Blog of Phyz. Briefly, I've been teaching high school and college-level physics since 1998, and in that time I've seen a lot—but nothing like what we're all dealing with now.
In addition to my teaching duties, I am the secretary and webmaster of Physics Northwest (group of physics teachers in the suburbs north and west of Chicago), and we've worked with our own teacher network as well as the TAP-L email list to assemble a long list of available online resources for teaching physics. This list of information has been posted to the front page of the Physics Northwest website at https://sites.google.com/site/physicsnorthwest/
Update 3/28/20: Here's a new and improved Google Sheet version of Matt's collection that we've been working on: Physics Distance Learning Resources. Consider it Version 1.0, and load us up with links we missed down in the comments. Remember: Google Sheets can have tabs. This sheet has four tabs (so far). Check them all out.
I apologize that the list isn't formatted and organized yet, as I've been busy tackling my own struggles with online teaching this past week, but now that I'm on spring break I'll have some time to tweak the list (so stay tuned). Any suggestions for additions and/or edits are welcome.
Take care, folks. It's a rough time for the lot of us, but in times like this I like to remind myself of the old Marine Corps motto: Improvise, Adapt, Overcome.
Cheers - Matt Lowry

And if you click the Physics Northwest link above, you will see a collection of great physics teachers, some of whom you may know from Twitter or elsewhere.
