Big Picture – Where we are heading  Learn how to:  Classify Organisms  Use Microscopes  Bring it together using critters and water samples from our classroom pond

Science Today  Concept Maps out and Ready  Clarifying Questions  Quiz  Set Up Journals for Classification  Classification Notes and Discussion  HW - Yes

Please Clean Table Tops of all extra stuff  Need Pencils and Erasers  Brain On  Have Journal, highlighter available for use after QUIZ

Done with Test? Remain Silent….. And…. 1.Put Blue Test Back in Pile on Back table 2.Staple your CONCEPT MAP BEHIND your test answer sheet and file in alphabetical sorter 3.Get Supplies – Back Corner counter  Glue Stick  Reading Article Instructions – SD Zoo  Article – “Why do animals have scientific names?” 4.Make a new Section Title in Regular part of Journal called “CLASSIFICATION” 5.Glue Article and Instructions into Journal 6.Add to table of contents 7.Read for understanding the article – ANNOTATE/HIGHLIGHT 8.Answer questions in your journal

Read Article from the SD Zoo – Answer in Complete Sentences in Your Journal – Glue Stick Article into Journal  What language are most scientific names based on? Why?  Who is credited with the current system of classification? When did he do his work?  What does Sarcorhamphus papa mean in Latin? What is the common name of this animal?  What two names are used to clearly identify a specific animal or plant?  What is a subspecies? Give a scientific name of a animal listed in this article that has three names?

Classification  A system to sort out organisms based on their properties  Scientific name is called TAXONOMY (based on Greek word taxa = “to sort”)  Observations used to determine similarities and differences in organisms

Kingdom Phylum Class Order Family Genus Species

Kingdom – “King” Phylum- “Phillip” Class – “Came” Order – “Over” Family – “For” Genus – “Great” Species – Spaghetti

Current System Used for Living Things  Carl Linnaeus 1700’s  The species name is sometimes called a binomial (a two-term name). For example, the zoological name for the human species is Homo sapiens: human  In this case, Homo is the generic name and refers to the genus; it is capitalized; sapiens indicates the species: it is written in lower case.

Types of Classification Keys  Branching Key (Visual)  Dichotomous Key (words with either or)

Branching Key  Asks Yes or no Questions  “Branches” outward from main question  Ends when a unique answer is in place for all items

Practice – Homework on your own  Branching Key – Two Options  OPTION A – Max Points = 115%  Monkeys with Extra Credit Available (harder and will require more work)  Option B – Max Points = 90%  Wacky People – 12 of the 15 sorted and in branching key  Complete Reading article and answer questions  Make Sure JOURNAL IS UP TO DATE  This is due on TUESDAY

This is the end of Friday Lesson

Dichotomo us Key  “Di” – means 2 “It is either this or that”  Look at first item  Ask Question #1 – move on to question it directs you to

Monkey Classification Key 1.Branching Key developed  Partner will Grade it  Choose three critters – #5, 10, 7  Use key to see if you come up with correct name  Make comments on sheet – Good things about key … suggest improvements  Repeat with Dichotomous Key – Check #’s 2, 6, 4  Assign a Grade – write the word next to their name  Above and Beyond - Made a key that was super easy to use and completely accurate  Proficient – made a key that got the job done for at least 10 of the 12 animals  In Progress – Does not meet expectations yet  NOTE EXTRA CREDIT ---  3 Stars --- scientific name for all and source of info listed  1-2 Stars – scientific name for most – may or may not have sources listed
