9. This Periodic Table Tree.

"Oh chemistree, oh chemistree! How nerdy are your branches?" Of the ninety-two naturally occurring elements here are twenty-eight found in the human body. My gold ornaments represent the elements found in larger than trace amounts (oxygen, carbon, hydrogen, nitrogen, calcium, phosphorus, potassium, sodium, chlorine, magnesium and sulfur) while the red ornaments represent elements found in trace amounts (aluminum, arsenic, boron, cadmium, chromium, cobalt, copper, fluorine, iodine, iron, manganese, molybdenum, selenium, silicon, tin, vanadium, and zinc). Too much? #chemistry #chemistree #christmastree #christmas #merrychristmas #biology #humanbiology #fearfullyandwonderfullymade
