Classification: Sorting It All Out Chapter 7: Classification
OBJ 1: List the 7 levels of classification • Warm-up: Think about the different ways humans classify things. List at least 5 things we classify into groups. (like library books, department stores …etc ) • Homework: Read pages 160-165.
Classifying Shoes • Page 159. Follow the procedures. • Each person needs to answer the questions in their own notebook.
Why classify? • Classification: the arrangement of organisms into orderly groups based on their similarities. • There are 3 domains • There are 7 levels of classification & they are in a certain order • Make it easier to know… • How many known species are there? • What are the characteristics of each? • What are the relationships between these species?
KPCOFGS • Kingdom • Phylum • Class • Order • Family • Genus • Species
Kingdoms • Archaebacteria • Eubacteria • Protista • Fungi • Plantae • Animalia
Phylum • ~ 36 • Chordata- animals with hollow nerve cords • Echinodermata- animals with spiny skin • Anthophyta- plants that flower
Class, Order, Family, Genus, Species • Each Class contains similar Orders • Each Order contains similar Families • Each Family contains similar Genera (genus) • Each genus contains similar species • Each species contains organisms that have THE SAME CHARACTERISTICS
OBJ 2: Explain the importance of having scientific names for species • Warm-up: none. • Homework: Complete the Section Review page 165 as you read. • Agenda: • 7 levels of classification! (See previous slides)
OBJ 3: Explain how scientific names are written OBJ 4: Be able to use a dichotomous key • Warm-up: next slide. • Homework: Read/ study text pages 166-167 *Memorize 7 levels of classification • Agenda: scientific names, branching diagrams, dichotomous keys
Classification Basis • Carolus Linnaeus – founded taxonomy (the science of identifying, classifying, and naming living things ) • Classify by SHARED characteristics • Similar…now by EVOLUTIONARY CHARACTERISITICS
Genus & Species • When scientists name a species they usually identify it by their last 2 classification groups, genus & species • In Latin & Greek…so it is universal. • Homo sapiens • Genus is capitalized • Species is lower case • In itallics
Branching Diagrams • Show the evolutionary relationships and how they have similar & different characteristics
Branching Diagram • Review page 162 Fig. 4 • You try! (page 163) • Frog, snake, kangaroo, rabbit • What do you think is the one major evolutionary change between one organism & the next? (Write them on your diagram)
Write Down your favorite animal (dogs not allowed) • Research the classification for your specific animal • Compare your animal with your neighbors…. • how similar are your species? • Where do they diverge? • As a class, try to determine who you are closely related to.
Dichotomous Keys • An aid to identifying unknown organisms that consists of pairs of descriptive statements • Of each pair of statements, only one will apply to the unknown organism • Each statement will lead to another statement until the description only describes one known species
Conclusion • What are the rules for writing a scientific name? • What is a dichotomous key? How does one work?
OBJ 5: List the 6 kingdoms, and provide 2 characteristics of each. • Warm-up: Why do scientists use scientific names for organisms? • Homework: Read text pages 168-171 and do the Section Review on page 171. *Memorize 7 levels of classification. TEST on April 18th (Thursday) • Agenda: dichotomous keys
Can you think of a mnemonic device to help you remember the levels of classification? You have 5 minutes to work with a partner and see what you can figure out!
Dichotomous Keys • An aid to identifying unknown organisms that consists of pairs of descriptive statements • Of each pair of statements, only one will apply to the unknown organism • Each statement will lead to another statement until the description only describes one known species
Recap • What are the 7 levels of classification? • What are the rules for writing a scientific name? • What is a dichotomous key? How does one work?
The 6 Kingdoms • Is your kingdom multi-cellular or unicellular? • Is your kingdom prokaryotes or eukaryotes? • What are the common characteristics of your kingdom? • How does your kingdom obtain nutrients? • How does your kingdom reproduce? • Create a PowerPoint with the information you find. You will share your information with your classmates. Make sure to include pictures. Have 1 slide for each question. You have 30 minutes.
Kingdom Groups • Archaebacteria # 1 • Eubacteria # 2 • Protista # 3 • Plantae # 4 • Fungi # 5 • Animalia # 6
OBJ 5: List the 6 kingdoms, and provide 2 characteristics of each. • Warm-up: none • Homework: *Memorize 7 levels of classification. TEST on April 18th (Thursday). Chapter Review on pgs 176-177 #1-14 and 21-24 (due Wed.) • Agenda: Continue kingdoms
Task: The 6 Kingdoms • Is your kingdom multi-cellular or unicellular? • Is your kingdom prokaryotes or eukaryotes? • What are the common characteristics of your kingdom? • How does your kingdom obtain nutrients? • How does your kingdom reproduce? • Create a PowerPoint with the information you find. You will share your information with your classmates. Make sure to include pictures. Have 1 slide for each question. You have 30 minutes.
I’m a single-celled organism that lives in pond water. • I am green and produce my food by photosynthesis. • I can move from place to place using a tail called “flagella” • Sometimes I use food obtained from other organisms. • WHAT AM I?
