1Binomial Nomenclature Scientific NamingScientific Name Game
2It is the abbreviated form of the scientific name of Escherichia coli Ever hear of E. coli?It is the abbreviated form of the scientific name of Escherichia coli
3T. rex. Tyrannosaurus rex Often lazy scientists just abbreviate the Genus with just a letter.
4Binomial Nomenclature two terms: the genus and the species Example: Common name = sugar pine Scientific name = Pinus lambertianaponderosa pine: Pinus ponderosa lodgepole pine: Pinus contorta
5Escherichia coli or Escherichia coli SCIENTIFIC NAME RULESGenus is CAPITALIZED (written first)Species is lower caseWritten in LatinItalicized OR underlined
6Carolus Linnaeus: devised the binomial nomenclature system 1707-1778 Studied medicineDisappointed parents that he did not enter priesthoodStudied plants to make medicines

9Biologists prefer to call organisms by Their scientific names rather than their common namesNo two species have the same scientific name although they may share a common genus. The genus name shows a very close relationship.Felis domestica .....house catFelis leo lionFelis onca jaguarFelis pardalis ocelotFelis concolor mountain lion
17Divide into YOUR LAB GROUPS You will classify at least 15 LEAVES Tape leaves at the end of the divisions
18LEAF ACTIVITY EXAMPLESee there is a leaf at each dead-end.

20TipsUse measurements rather than terms like "large" and "small“(larger than 6”, smaller than 6”)Make the first choice a positive one - something "is" instead of "is not".If possible, start both choices of a pair with the same word.1. a. wings covered by an exoskeletonb. wings not covered by an exoskeleton
