A continuous zoom from the atom to the galaxy (or back), with each level coming in from the middle and its measurement. The classic "just so you get an idea".
Plus the typeface and an optional letter outline, in every template.

Export it without background and put it on a track above your clip: the animation plays over your video.
Size comparisonSilhouettes drawn to real scale over a ruler: "this is as long as 3 buses".
Rocket trajectoryLifts off, climbs through the layers of the atmosphere with the altimeter counting, and reaches orbit.
Solar systemThe eight planets orbiting at their relative sizes; the one you pick is highlighted and pulls out its card.
Layers in cross-sectionConcentric circles opening from the middle with their label and their measurement: the inside of the Earth…
Stacked strataThe same idea in horizontal bands: soil layers, sea levels, price tiers or any "this sits on top of this".
Human bodyA silhouette with the organ you choose highlighted, beating, and its card beside it.
Cycle with stepsThe steps around a ring that completes itself, with a marker going round.
