There should be a more interactive science experimentation gameplay loop where you can utilize the flora and fauna in innovative ways. Take the science equipment from SN1 and give it an actual function to test and analyze various items.

i suggested to have reseach side quests for most of the flora and fauna: https://subnautica2.nolt.io/8257 - it would be a parallel gameplay aspect to the main story line. experimentation loops could work with this after going through the basics.
