Educative Amazing Bismuth Crystal

Bismuth is a chemical element with symbol Bi and atomic number 83. Bismuth, a pentavalent poor metal, chemically resembles arsenic and antimony. Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores. The free element is 86% as dense as lead. It is a brittle metal with a silvery white color when freshly produced, but is often seen in air with a pink tinge owing to surface oxidation. Bismuth is the most naturally diamagnetic and has one of the lowest values of thermal conductivity among metals.

Educative Salt Ponds in San Francisco Bay

Salt evaporation ponds, also called salterns or salt pans, are shallow artificial ponds designed to produce salts from sea water or other brines. The seawater or brine is fed into large ponds and water is drawn out through natural evaporation which allows the salt to be subsequently harvested. The ponds also provide a productive resting and feeding ground for many species of waterbirds, which may include endangered species. The ponds are commonly separated by levees.

Sad New Zealand Penguins in Need of Sweaters

Penguin sweaters, also known as penguin jumpers, are sweaters which are knitted for penguins that have been caught in oil slicks. When an oil spill affects penguins, they are dressed in knitted sweaters to stop them preening their feathers and to keep them warm, since the spilled oil destroys their natural oils. This also prevents them from poisoning themselves by ingesting the oil. The sweaters are removed and discarded as soon as the penguins can be washed. The original project has been completed, but the knitting pattern is still available on-line, as subsequent oil spills make it necessary. The extra sweaters are kept on behalf of the Wildlife Rescue Team.
