Thanks for mentioning your site and have you seen http://scaleofuniverse.com/ ? I sometimes use that site as a lecture tool when a larger context of time and space is useful.
Interesting mix. In addition to videos, there are interactives like https://learn.genetics.utah.edu/content/cells/scale/ and https://www.nikon.com/about/sp/universcale/scale.htm .
It's basically chunked powers-of-ten, so two 1000x frames ("micro view" um->mm, and "nano view" nm->mm) get you down to 'atoms look like sand'. It seems to provide useful scaffolding - a place to hang some flavors of rough-quantitative knowledge. It seems to at least sometimes work nicely with bionumbers "how big is a X" searches, as "N um"-like answers permit "oh, so it's about this (tactile kinesthetic) big - so it's bigger than Y and smaller than Z and about the same size as W - hmm, so I wonder how many X's there are in a mumble - new search: 'how man X in a mumble'". But that's purely anecdotal, and from very limited experience.
