Presentation transcript:

Sort candy into groups write down how you sorted the candy Student A is the scribe and will write down how the pair sorted the candy Student B is the reporter and will tell how the pair sorted the candy

 Plants  Rocks  Animals

Why is observation important when classifying things?

scientist need to observe the characteristics of organism in order to group them together based on their similarities.

Classification: Is the process of grouping things based on their similarities.

Why do Scientists Classify?

 To help us study the earth  To help us organize all the species we discover...

 To give every species a name based on a standard method so scientists from different countries can talk about the same animal without confusion It is always written in the Latin Language

o Biologist use classification to organize living things into groups so that the organisms are easier to study

Who is Carolus Linnaeus?  Carolus Linnaeus was a Swedish botanist  Developed a 8-level (taxa) classification system based on similarities between organisms

An organism is known by two names… For example: o Canis lupus is the scientific name for a gray wolf. o Canis is the genus name o lupus is the species name o This system uses a binomial nomenclature

The first word in an organism's scientific name is its genus genus: is a classification grouping that contains similar, closely related organisms

The second word in a scientific name describes a distinctive feature of an organism Together, the two words indicate a species A species is a group of similar organisms that can mate with each other and produce offspring that can also mate and reproduce

Binomial Nomenclature  Bi means two  Nomen means name  A binomial nomenclature is a classification system using two names to identify an organism

The Eight Level System  Domain  Kingdom  Phylum  Class  Order  Family  Genus  Species  Dumb  Kids  Playing  Catch  On  Freeways  Get  Squashed

Classification of Humans Domain: Eukarya ( Dumb ) Kingdom: Animalia (Kids) Phylum: Chordata (Playing) Class: Mammalia (Catch) Order: Primata (On) Family: Hominidae (Freeways) Genus: Homo (Get) Species: Homo sapiens---(Squashed)

How does it work?  There are 6 broad kingdoms  Every living thing that we know of fits into one of the six kingdoms  Each level gets more specific as fewer organisms fit into any one group

 A Sample Classification  The lion belongs to the following groups:  Kingdom Animalia (includes all animals)  Phylum Chordata (includes all vertebrate animals, as well as some other more primitive ones)  Class Mammalia (includes all mammals)  Order Carnivora (includes carnivorous mammals, from bears to raccoons to harbor seals)  Family Felidae (includes all cats)  Genus Panthera (includes the great roaring cats: lions, tigers, jaguars, and leopards)  Species leo (lions!)
