History of phosphorus • Name origin: In Greek, "phôs" is light and "phoros" is bearer. Therefore, phosphorous is the "light bearer. • Discovered by Hennig Brand in 1669 in attempt to create the Philosophers Stone. The stone is said to turn all solids into gold (which is absolutely unreal.) Brand wanted to keep the element a secret, until he told a few other scientists. Even Robert Boyle got his hands on the element. It wasnt until the late 18th century that it was discovered for use in fertilizer. • Phosphorus is known to be found in DNA and RNA ever since the genetic codes existence. Depiction of r e!

The Element Boxes It became apparent that elements became the subject of interest in NPMM. Therefore, each eighth grade student decided to create an element box, containing basic information about each element. Each one comes with aKeynote presentation and video (hidden in a QR code) ofeach element. Mine is about phosphorus, an element you have learned has an abundance of uses, an odd historyand one heck of an explosion. Each box also has artifacts, which symbolize what the element is used for.
