For my science discovery this week I researched the silkworm moth. The Three stages of morphology of silkworm moths is larvae, cocoon with pupa inside, and finally adult. Adults have four wings covered with scales. Silkworm moths' natural food is the mulberry tree. Silkworm moths can only be found in captivity today. Silk worm cultivation began more than 5000 years ago in China. The production of raw silk by raising silkworms is called sericulture. Sericulture spread to Korea, then Japan, and then southern Asia. One cocoon is made into a single thread of about 914 meters long. To make one pound of silk about 3000 cocoons are needed. To make silk out of the cocoons boil the cocoons for about five minutes, then find a single strand that comes off easily and wind it onto a stick or pencil. (Several strands are combined to make one thread).
For my science discovery this week I did black eyed susans. Their scientific name is rudbekia hirta. Black eyed susans are in the asteracea family and are a flowering plant. Black eyed susans are native to the eastern and central U.S.. Black eyed susans are the symbol of Maryland. There are many plants with the common name of Black eyed susan. Black eyed susans have bright yellow petals and and a dark brown middle.
