I once saw a science education state standard, that required teaching both 'atoms are conserved in chemical reactions', and 'atoms are electrically neutral; when changed, they're no longer atoms, but ions'. Two historical threads of definition, left for students to reconcile. Terminology in primary-school science education can have a twilight zone feel, kind-of sort-of resembling science terminology, but as seen from a skewed alternate reality, disconnected from actual science community and practice. So it's not just cs learning material.
