Taxonomy:

Taxonomy The science of classification The science of classification Classification is important in biology because it allows scientists to be able to distinguish between different organisms (Species level) Classification is important in biology because it allows scientists to be able to distinguish between different organisms (Species level) It also allows similar organisms to be grouped together and helps us to look at how they might have evolved (Kingdom-Genus) It also allows similar organisms to be grouped together and helps us to look at how they might have evolved (Kingdom-Genus)

Example: Domestic Dog Kingdom: Animalia – all animals Kingdom: Animalia – all animals Phylum: Chordata – have a vertebrae (or backbone) Phylum: Chordata – have a vertebrae (or backbone) Class: Mammalia – mammals (have fur and are warm- blooded Class: Mammalia – mammals (have fur and are warm- blooded Order: Carnivora – eat meat Order: Carnivora – eat meat Family: Canidae – wolf-like carnivores (includes wolves, foxes, jackals, coyotes, and dogs) Family: Canidae – wolf-like carnivores (includes wolves, foxes, jackals, coyotes, and dogs) Genus: Canis – includes wolves, dogs, coyotes, and jackals Genus: Canis – includes wolves, dogs, coyotes, and jackals Species: lupis – Gray Wolf Species: lupis – Gray Wolf Subspecies: familiares – domesticated form of the wolf, or dog Subspecies: familiares – domesticated form of the wolf, or dog

Now let’s make our own classification system…for cars

Two Wheels Four Wheels

Of the Four Wheels—let’s classify them further... TruckCar

Let’s classify the cars further... 4-doors2-doors

Let’s take the sports cars down to the next level Convertible Hard top

And finally—let’s further classify the 4-door cars SilverRed

Here’s what our classifications look like in the end Transportation Two wheel Four wheel Truck Car 2-door4-door ConvertibleHard-topSilverRed Kingdom Phylum Class Order Family

Today’s Lab Activity You will be classifying a mixture of food items into groups. IMPORTANT!!! If you have any nut or fruit allergies please let one of the teachers know before you do the lab!!!
