How are living things alike, yet different? Bell work 2/6 How are living things alike, yet different? What is it about organisms that we use to classify them? (Their characteristics) How can we determine their characteristics? (Observations) How many characteristics do you think it would take to determine what the organism is? (2,3,4, etc.)

“Life” ball- 1o min Rules: 3 seconds or less to say a characteristic of life Bad throw= out Not catching a good throw= out Being a bad sport/ disrespectful= out Intercepting someone’s throw/catch= out Talking without ball in hand= out

Grouping living things Classification Grouping living things

Introduction- 10 min. Think about your favorite store How is the store organized? Create a diagram showing how the merchandise is organized in the store. Why do we need organization?

History (DO NOT WRITE) Aristotle- one of first people to classify organisms Placed organisms into 2 large groups (plants and animals) 1700- Linnaeus Classified organisms based on similar structures Present day Systematics Classifies organisms based on all evidence known about an organism 5 Kingdoms! Greek philosopher from (384 BC to 322 BC)

Classification Living things are classified into 7 groups from the largest (most general) to smallest (most specific) Kingdom Phylum Class Order Family Genus Species

Example: 1. Humans 1. Kingdom Kid 2. Females and non-females 2. Phylum Female/ Phylum Male 3. Long hair and not- long hair 3. Class long hair/ Class not-long hair 4. T-shirts and not- T-shirts 4. Order T-shirt and Order not- T-shirt 5. Sneakers and not- sneakers 5. Family sneakers and Family not-sneakers 6. Wrist decoration and no wrist decoration (watch, bracelet, gel-band, etc) 6. Genus wrist decoration and Genus not- wrist decoration 7. Wearing earrings and not- wearing earrings 7. Species earrings and Species not-earrings

Bell work 2/9 What 2 levels of organization do you use when naming an organism using binomial nomenclature? Genus and species

5 Kingdoms Bacteria (simple unicellular organisms) Archaea (simple unicellular organisms that live in extreme environments) Protista (unicellular but more complex than bacteria or archaea) Fungi (unicellular or multicellular and absorb food) Plantae (multicellular and make own food) Animalia (multicellular and take in food)

Scientific Name Binomial nomenclature- gives each organism a two-word scientific name Genus- a group of similar species Species- a group of organisms that have similar traits and are able to produce fertile offspring Example: Brown bear Ursus arctos

Brown Bear Classification (pg. 313)

Classification tools Dichotomous Key- a series of descriptions arranged in pairs that lead the user to the identification of an unknown organism Turn to page 314 in book

Activity Work with a partner to classify the candy on the desk using a dichotomous key! DO NOT eat the candy!!!

Explain how using a dichotomous key can help you identify an organism. Bell work 2/10 Explain how using a dichotomous key can help you identify an organism.

Activty Create a dichotomous key to classify the creatures Hint: start with a characteristic that will divide the creatures into 2 groups  then, divide those 2 groups into 2 smaller groups Example: # eyes, hair/no hair, ears/no ears The creature has 2 eyes…. Go to step 2 The creature has 1 eye….. Go to step 4 http://www.agnespflumm.com/documents/preposterous_dichotomous_k eys.pdf
