Physics High is committed to producing content that teaches physics concepts at a level a high schooler can understand.
See www.physicshigh.com for all my videos and other resources.

As well as this I produce a podcast series called Deep Impact interviews with science communicators as to what they do, what drives them to communicate their craft
You will find these on the channel and also on podcast sites such as Spotify, Apple and Google podcasts
