You will not be able to do it for your class.  It takes a lot of time, skill, boats, oysters, and luck!\n\nSee for example:\n\nhttp://www.spc.int/coastfish/News/POIB/12/POIB12.pdf\n\nWhen I visitted Broome, in northern Western Australia, I saw how it is done.  It involves a skilled worker doing surgery on the living oyster, to place a "seed" into its matle.  Then, the oyster is returned to the sea, to recover, if it can, and to slowly cover the seed with extra nacre.  Then, it is harvested again; this time, the oyster is killed.\n\nYou need baby oysters, called sprat.  You need seed pearls.  You need to learn the technique, handed down from Mr Mikimoto of Japan.\n\nIt is not suitable as a practical exercise for schoolkids.

Why not take a page from Archimedes' Eureka! moment?\n\nMeasure the density, then ask a jeweler.

1. pearls are made because of an irritation to the oyster inside the shell. the irritation is then covered by the oyster w/ calcium carbonate & after many years it is now a pearl.  a diamond is made from carbon from decaying plants & animals buried in the ground for  millions of years then subjected to immense pressure of the earth to form a rock-hard diamond.\n\n2.  you mean sea water? sea water is too salty w/ at least 3.5% salinity making it undrinkable for humans.\n\n3. the fish dont 'see' using their eyes.  they use a variety of organs to find their way in the water.  when you look at a fish, they have a line running through the middle of the body up to the tail. it is a sensory organ used by the fish to ' see'.  others have acute sense of smell or taste like the sharks.  others have a rostral organ in their snout w/c acts like an electrical field receptor.\n\n4. maybe women because the current world record holder in the free diving catergory is a woman named streeter who can hold her breath for 6 min while diving to 525 feet.

I've never constructed a double helix before, but try using straws with wooden skewers run through them [to act as stabilizers] and spray-painted styrofoam balls.  I know that styrofoam balls aren't actually household items, but you can pick them up pretty easily at a local arts and crafts store.  \n\nIf the teacher doesn't mind, I suppose you could use apples and oranges...  ^^\n\nAnything that is porous and easy to skewer ought to work.  Like an eraser.

Not all black pearls are created equally. For example, the composition of a perfectly round, perfectly clean lustrous natural color black Tahitian south sea cultured pearl necklace is a true rarity. One can only imagine how rare such a grouping of pearls truly is. Each year, hundreds of thousands of oysters are cultured in the mysterious islands off French Polynesia. And each year, thousands of farmers stand there sun-burned before their harvests, having waited six years, in the hopes that just one in one hundred pearls will return a paragon; a large, round, lustrous pearl. For black pearls, the job is doubly hard as black is the absence of light. We all know that luster or the reflective quality of a pearl is the amount of light a pearl shows. Here we have a classic dichotomy. How does a pearl that appears to be dark shine at the same time? To quote John Steinbeck in his novel, The Pearl, "it captured the light and gave it back in a silver incandescence."\nThe black pearl, due to it's rare quality is far more precious.
