Topic: CLASIFICATION Essential question: Why do scientists organize living things into groups?
3
Benchmarks: SC.6.L.14.1, SC.6.L.15.1 Objectives 1. Explain why scientists classify organisms into groups. 2. Describe the levels of classification. 3. Understand that the more classification levels that two organisms share, the more characteristics they have in common. 4. Use a dichotomous key and/or a field guide to identify organisms based on their structural characteristics
4
Vocabulary Classifying Dichotomous Key Taxonomy
5
Biologists use classification to organize living things into groups so that the organisms are easier to study. Classification is the process of grouping things based on their similarities. The scientific study of how living things are classified is called taxonomy. Why do scientists organize living things into groups?
6
There are 8 Major Levels of Classification Domain Kingdom Phylum Class Order Family Genus Species DO YOU THINK IT WOULD BE EASY TO REMEMBER?
7
Class Discussion and Homework Here is a great idea! I remember the 8 levels of classification using the following sentence! Don King Plays Chess On Fridays Generally Speaking! You can make up your own! Homework: Make your own!
8
THERE ARE 3 DOMAINS EUKARIA (cell with nucleus) BACTERIA ARCHAE
9
From Domain to …? Kingdom!
10
There are so many different organisms on Earth To help deal with the great diversity of organisms, scientists have assigned them into general groups called Kingdoms. The members of each Kingdom share physical characteristics and similar feeding patterns.
11
There are 5 Kingdoms! Plant Animal Fungi Protista Monera –Bacteria –Archea DO YOU THINK IT WOULD BE EASY TO REMEMBER?
12
Media Center Symposium! Discussion What Kingdom was the one discussed?
13
Background The original two Kingdoms were Plant and Animal, which remained the only Kingdoms until the middle of the 20th Century.
14
What are the 5 kingdoms? Who remembers?
15
Interactive Notebook pg. 61 Trace your left hand onto the page You will label your left hand as of the five kingdoms as we discuss them! Here is a Handy Way to Remember the 5 Kingdoms
16
How does symmetry affect how an animal lives? An example of a way to classify is by symmetry
17
Examples of ways to classify: Bilateral Symmetry 1 line of symmetry Mirror images Radial Symmetry Many lines of symmetry going thru a central point By symmetry: balance between 2 or more parts.
18
Animals with Radial Symmetry Equally spaced around a central point Do not have distinct front or back ends Live in water Move very slow
19
Animals with Bilateral Symmetry Larger and more complex Front and back ends Move quickly Streamlined body Sensory organs at the front of their body
20
Radial, Bilateral, or No Symmetry 1. LION
21
Radial, Bilateral, or No Symmetry 3. Butterfly
22
Radial, Bilateral, or No Symmetry 4. Sand Dollar
23
Radial, Bilateral, or No Symmetry 5. Sea Urchin
24
Radial, Bilateral, or No Symmetry 6. Jellyfish
25
Radial, Bilateral, or No Symmetry 7. Sponge
26
Radial, Bilateral, or No Symmetry 8. Sponge Bob

Dichotomous Key A dichotomous key is a guide for classification and identification, somewhat like a map through a classification system that was developed previously. – Dichotomous comes from Greek origin
28
Carolus Linnaeus
29
How does it work? By asking a series of questions to which there are only two possible answers with respect to the object to be identified, the key leads users toward the proper identification. –Many parts of the natural world that have been classified, categorized and grouped can be identified using a dichotomous key. Dichotomous keys can be developed to identify anything in any sort of classification.
30
Dichotomous Key Lab Let’s develop our own dichotomous key to better understand them!
