ELI5: Why do science labs always so often use composition notebooks and not, for example, a spiral notebook?
gpt
One of the primary rules for science labs and GLP (good laboratory practice) is to NOT destroy data.  

If there's an error, you can't use an eraser, pencils are not allowed, white-out is not allowed; a correction must be made by crossing out the error (with a single line so that what was written is still visible), and then initialing and dating the correction.

Also part of "not destroying data" is that the official lab notebook has pages that are numbered (from factory), and the QA department and other auditors (FDA for example) will definitely question, and possibly invalidate the lab work performed or even close the lab, if there are pages that are missing.
