Could use more attention to units -- see my 1-page Physical Units Factor Tables , which gives the mathematical relationships between 50 classes of units, it's based on the physically-typed calculator /programming language Frink, which everyone should use for physics problems. https://substack.com/@enonh/p-148207296
frinklang.org (requires JRE for install, or use online without install, the units.txt file is worth browsing, also see the sample programs such as the solar system simulator)
For actual toddlers, a point-source light over the bathtub gives sharp shadows for use as a wave-tank for exploring interference and seeing water flow effects on the surface.
Nice explanation and introduction to flow fields. Meat and potatoes for hydrodynamicists.
Fun story from undergrad. A friend and I took intro to fluid dynamics before we took E&M. We walked into the E&M class and the prof started with electric fields. I leaned over and said: Hey, Drew! It's inviscid flows! 😉
Wound up in radiation hydrodynamics. That uses ALL the terms.😱

It allows sophisticated 2-D flow and thermal simulations.
wow this is great, thanks Michael. Love your blog btw.
