Monday 19 September 2011Topics: Classification of LifeDO NOWDo you feel prepared for
the presentation? What did your group do in
order to prepare? If you were to do this
project again, what would you do differently?
OBJECTIVESDescribe the
defining characteristics of each main category of life.
HOMEWORK• Read section 18-3
(Kingdoms and Domains). Use this information, along with your notes, to complete the graphic organizer
AGENDA• Classification
presentations
Bacteria Domain
SULFOLOBUS ACIDOCALDARIUS
ARCHAEA
OBJECTIVES Describe the defining characteristics of each main category of life.
Made of cell •Extreamophiles from archaea are prokaryotic•Extreamophiles from archaeaare unicellular
Reproduce
Have genetic code
Use material and energy
Respond to their environment
• extreamophiles from archaea reproduce asexually
•Extreamophiles from archaea keep their DNA floating within the cell
•Extreamophiles from archaea are both heterotrophic and autotrophic(they do not use photosynthesis some use sulfur and iron)
•Extreamophiles from archaea live in extreme environments such as acid, freezing water and boiling water!
Archaea life Characteristics
OBJECTIVES Describe the defining characteristics of each main category of life.
Sulfolobus Acidocaldarius
Domain= ArchaeaKingdom= Crenarchaeota Phylum= CrenarchaeotaClass= ThermoproteiOrder= SulfolobalesFamily= SulfolobacaeaGenus= SulfolobusSpecies= Acidocaldarius
OBJECTIVES Describe the defining characteristics of each main category of life.
Interesting Facts
They need the harsh conditions to interact/ reproduce
They live in acid
OBJECTIVES Describe the defining characteristics of each main category of life.
Eukaryote DomainVery diverseOnly
commonality is cells contain a nucleus
Unicellular or multicellular
Includes 4 kingdoms
OBJECTIVES Describe the defining characteristics of each main category of life.
Plant Kingdom
Protist KingdomEukaryoticMost are
unicellularSome
autotrophic, some heterotrophic
Most are aquatic

Fungi
OBJECTIVES Describe the defining characteristics of each main category of life.
Fungi are eukaryotesFungi are mostly multi-cellular but sometimes
unicellularFungi are part of the Eukarya domainFungi are heterotrophs. Most fungi feed on
decaying matter but few feed by capturing live animals such as pleurotus streatus
Fungi

Exit ticketWhat went well in your group’s
presentation? Is this something you anticipated?
What do you think you could have worked on more to make things run more smoothly? What would you have done to change it?
OBJECTIVES Describe the defining characteristics of each main category of life.
Tuesday 20 September 2011Topics: Classification of LifeDO NOWHow are the domains
Bacteria and Archaea different? Similar?
How are the kingdoms Plantae and Fungi different?
OBJECTIVESExplain how a new
species is placed into the appropriate categories.
Follow a dichotomous key in order to classify a species.
HOMEWORKRead pages 448-450
and answer the 6 Section Assessment questions in your notebook.
AGENDA• Summarize
presentations• What is a dichotomous
key?• Create your own
dichotomous key!
Fish
Birds By shreena, nahum, alondra, and charlie
OBJECTIVES Describe the defining characteristics of each main category of life.
Characteristics of LifeMade of cellsReproduceHave a genetic code (DNA)Use energy and materials Respond to their environmentAre birds prokaryotic or eukaryotic?Are they unicellular, multicellular, or both?• Birds are eukaryotes which means they have a nucleus• Birds are multicellular
OBJECTIVES Describe the defining characteristics of each main category of life.
Do they reproduce sexually or asexually – or some of both?Birds reproduce sexually
Where do they keep their DNA? Inside a nucleus within a cell or just floating within the cell?
The DNA is inside the nucleus Are they autotrophs or heterotrophs?How do they make or get food? • They are heterotrophs • Use their beaks to pick things In what kinds of environments do these organisms
live?Give examples of how these organisms can respond to their environment.They live in natural ecosystems and human society in many different waysThey fly to the south when its winter

OBJECTIVES Describe the defining characteristics of each main category of life.
Costa Hummingbird
It is a type of hummingbird.It's a very small hummingbird, at maxium
it can be 3 to 3 1/2 inches at full size.The feathers on its face is bright purple.They are found in southwestern united
states, California, and Mexico.

OBJECTIVESExplain how a new species is placed into the appropriate categories.Follow a dichotomous key in order to classify a species.
Dichotomous keys!A method to classify organisms
based upon physical traitsSeries of paired statements that
are oppositesUltimately results in the
identification of the organism in question
OBJECTIVESExplain how a new species is placed into the appropriate categories.Follow a dichotomous key in order to classify a species.
Dichotomous keys!Everybody take off 1 shoe and place
it on the kidney table (That’s right. I went there.)
Take 1 minute to silently write all possible traits that can be used to classify the shoes (e.g. laces, flats, patterns, etc)
Take 2 minutes to discuss with your elbow partner the traits you brainstormed
OBJECTIVESExplain how a new species is placed into the appropriate categories.Follow a dichotomous key in order to classify a species.
Dichotomous keys!Why do you think it’s important
that the paired statements are opposites?
Which types of traits do you think should appear first in a dichotomous key?
OBJECTIVESExplain how a new species is placed into the appropriate categories.Follow a dichotomous key in order to classify a species.
Dichotomous keys!More practice…
◦Individually, or with a partner, you will be able to classify leaf samples by following a dichotomous key
◦Turn to page 462-463◦Classify the leaves pictured by following
the key on the left◦I will draw samples for any potentially
unknown vocabulary on the board◦This sheet will be collected as classwork!OBJECTIVES
Explain how a new species is placed into the appropriate categories.Follow a dichotomous key in order to classify a species.
Dichotomous keys!With a partner, you will CREATE a dichotomous
key that can be followedPROTOCOL:
1. Observe your specimens and brainstorm a list of ALL traits that applies to them
2. Decide upon the order of which traits to categorize your specimens and move them accordingly (like we did with the shoes)
3. Make a poster of your key (either style of representing the info – the way it is in the book or how we did it on the board)
4. Draw and label the specimen at the end of each classification pathway, and put your names on the posterOBJECTIVES
Explain how a new species is placed into the appropriate categories.Follow a dichotomous key in order to classify a species.
EXIT TICKET(you may nibble on your specimens while writing)What was challenging about
creating your own key after following one that was already made?
What might make this process difficult in terms of classifying a species in real life?
How might a scientist avoid the difficulty?

DO NOW: Before fully reading Prompt 1,
what do you think the question is about? What indications did you have?
Read the entire Prompt 1. Underline what you believe are key verbs, and circle what you believe are important buzzwords.
OBJECTIVESEffectively write
an MCAS response about how to classify a species.
HOMEWORK• Create a study guide
sheet to use during a review game tomorrow (quest is 2nd half of class)
AGENDA• Practice MCAS
writing prompts with Mr. Lerner!
Brainstorm With your elbow partner, take 2 minutes to share
what you identified in the Do Now as key verbs and buzzwords.◦ KEY VERBS:◦ Identify◦ Justify◦ Describe◦ Explain◦ Determine
◦ BUZZWORDS: Closely related Classification Sea lions Two types of evidence
Individually…SILENTLY take 3 minutes to flip
through your notes and jot down (in the margins of the prompt) any information that you feel is relevant to answer the question.
Types of Responses:1. IDENTIFY
◦ Name something (1 sentence max)2. JUSTIFY (2-3 sentences)
◦ Reason for your answer3. DESCRIBE vs. EXPLAIN. (longer
explanation)1. Describe – give characteristics2. Explain – answers ‘how’ or ‘why’
4. DETERMINE1. Combo of describe/explain
Final steps…Re-organize the notes that you
took in the margin to correspond to which portion of the prompt it will answer.◦For example, all information that is
RELEVANT to part 1 should be separated from all info for part 2.
AS YOUR EXIT TICKET:◦Use all these steps to write out a
FULL response to Prompt 1.
