Tools like this are surprisingly effective for teaching, especially compared to static diagrams. Interaction makes the scale differences stick.

When my daughter is old enough, I'm definitely going to show her a bunch of visualizations on Neal's site as supplementary education. I learned so much from these visualizations as an adult, and even without being able to read you can get a sense of scale.

Fwiw, I've done a pinch-nail-hand-arms 1-10-100-1000 mm "body as size reference" a couple of times around 5ish. And a 1000x "micro view" "pinch is zoomed to arms size" "it's like a scale model or doll playset - everything zoomed together" world of "bacteria sprinkles, red blood cell candies (M&M minis or concave Smarties minis or Sweetarts - there's lots of cell candy analogs), hair poles, salt/sugar boxes". Stories of sitting on a grain of salt and eating... etc; pet eyelash mites. No idea if it actually worked.
I did some user-test videos, now only on archive.org.[1] Hmm... the "Arms, hands" video there now doesn't seem to play inline? - but does wget'ed and browsered. :/

Hey that's cool! I like that idea
Totally agree! Even as adults, the sense of scale hits differently when you interact with it. Your daughter will probably love discovering it too.
I felt like I was at a museum exhibit. It is fantastic.
