If you ask your co-workers for crystals and metals that also counts.as does cloning them.
Yep ask co workers does count wasn't sure about cloning, but anyways with the map I have seen anything from the cow plant berry deathflower, angelfish, young again potion, rare cryistals and metals, I have also seen the crystals and elements in time capsules.
Well the science lab should only have the rock and crystal dig sites, but after the Sims 4 Pets came the game started spawning dirt piles to dig in if cats and dogs are around they can pickup certain things and take them to their owners as little white blue present boxes. Sometimes they are pink and white though do have some excellen stuff in there from catnip to dog cat toys to dog and cat treats, also fish, low quality to high quality even angel fish, death flower and pretty munch anything.
Edit I also have seen a cat and down spawn as visitors to the science lab. it cracked me up must have been a bug.
