STEM Ed Resources Dissemination

I like the idea of having information about specific tools, uses, and other information to help people find and use resources efficiently.

MIT Tech TV (http://techtv.mit.edu/collections/physicsdemos/videos)
Free, linkable and downloadable videos of physics demonstrations.
I've found the easiest way to find applicable videos is to browse by clicking one of the tags.

PhET Interactive Simulations (https://phet.colorado.edu/)
"PhET provides fun, free, interactive, research-based science and mathematics simulations." Although the graphics are a bit old-school, they're excellent simulations on a variety of topics. They can be used in the classroom, as prep, or homework; simulations can be run online or downloaded. Various instructors have uploaded teaching materials based on the simulations; I've found a variety of clicker questions that are particularly helpful. MasteringPhysics incorporates PhET simulations in some of their tutorial questions, but I've found these to be a bit convoluted (parts a - h) and rather inhibits students' exploration of the simulation.

Veritasium (https://www.youtube.com/user/1veritasium)
A YouTube channel that posts various demonstrations, interview, etc. for science and engineering. The videos are engaging and have high production quality.
