The sequence of physics->chem->bio is more scientifically and logically sound. However, the traditional sequence within physics education needs to be rethought and revised too. In order to build a foundation for the rest of physics (and yes, chemistry and biology), physics needs to be taught at the atomic level at the start, rather than a quick glance at the end within HS physics. Obviously, HS kids don’t yet have the math background, but the “physics” (i.e. the physical understanding) of atomic physics can be taught conceptually, descriptively and intuitively without the math.
