2. Where to begin….

3. Scientists Start Classifying by looking at cells:

(have __________)
Non – Living
( ____ made of _________)

4. But there are so many living things…

5. It began in the 18th century…

7. Today’s Classification System vs. Linnaeus
Today’s/Modern System

8. Today’s Levels of Classification System
Scientists start by breaking plants/animals into kingdoms.
Scientist continue to sort these groups into even smaller groups.
Each time they sort, they use the organism’s features to decide whether or not the organism belongs to the group.
The largest classification group would be the “kingdom”

9. 6 Kingdoms of Living Things
Archaebacteria
Eubacteria
Protist
Fungi
Animals
Plants
One cell
One and many celled
Some move
Some make own food, some get food from other living things
Ex.

10. Each Kingdom is broken up into Phylum
Animal Kingdom
Plant Kingdom

11. Animal Kingdom
Vertebrates
Invertebrates

12. But is that enough….. Coming up tomorrow:
We will learn examples of vertebrates and invertebrates
We learn if and how these are classified even more
Look at the different categories of vertebrates and their characteristics
We will look at specific examples of a species with their “full names” and talk about what they mean.
