1 Periods 4 & 5 HW: Classification Levels Search for the YouTube video “Classification Levels”Classification Levels by Alyssa Dolny. Periods 4 & 5: Complete on Page 50 of your I.A.N. using Cornell Notes. Due TOMORROW. https://www.youtube.com/watch?v=jiLZ-BIfpkg

2 Classification Levels Essential Question: How can I use a hierarchical classification system to identify relationships among organisms?

3 HAPPY MONDAY 1/19/16 Bellwork : In 30 words….describe the process of buying a bottle of ketchup at the grocery store. For example…… – How do you find it? – What does it look like? – Where in the store is it?

4 What is classification? Name some things that we classify into groups. Why do you think we (humans) classify things into groups?

5 CLASSIFICATION ACTIVITY -Online Shopping -Grocery Store (Sorting Tree) -Do It Yourself

6 1.Netflix 2.Vehicles 3.Toy Store 4.Music 5.TV Shows 6.High School 7.Sports Each chart must include FOUR levels with at least FOUR examples per level.

7 Exit Ticket: In exactly 10 words describe why classification is important.

8 Museum of Natural History: 33 million things

9 Dichotomous Keys: TEKS 7.11A 1.Do you like to take walks through natural areas like prairies, woodlands, or along a riverside? 2.Do you enjoy exploring tide pools, snorkeling, swimming or scuba diving? 3.Have you ever come across a creature you didn’t recognize? 4.How did you identify it? Bellwork: Answer the questions below 1/20/16 You will need a pen/pencil, bellwork sheet, journal

10 Please set up page 1 in your journal for Cornell notes. Title “Taxonomy” Essential Question: Why is taxonomy important and helpful to scientists?

11 Classification is the grouping of objects or information based on similarities.

12 Taxonomy is the science of grouping and naming organisms. …… in other words, taxonomy is the process of classifying and naming biological (living) organisms. In Biology:

13 Phylogeny: The study of evolutionary relationships among organisms – one way to classify organisms

14 Let’s look at some animals

15 Devil Cat

16 Ghost Cat

17 Mountain Lion

18 Screaming Cat

19 Puma

20 Florida Panther

21 Cougar

22 Confusion in Using Different Languages for Names

23 There are at least 50 common names for the animal shown on the previous 7 slides. Common names vary according to region. How could we fix this problem?

24 Latin Names are Understood by all Taxonomists

25 Benefits of Classifying Accurately & uniformly names organisms Prevents misnomers such as starfish & jellyfish that aren't really fish Uses same language (Latin or Greek) for all names Sea”horse”??

26 26 Carolus Linnaeus 1707 – 1778 18th century taxonomist. Called the “Father of Taxonomy”. Classified organisms by their structure. Developed naming system known as binomial nomenclature. Two-word name (Genus and Species)

27 1.The genus name is written first (Capitalized). 2.The species name is written second (lower case). 3.Both words are italicized if typed or underlined if hand written. Example: Felis concolor or F. concolor Which is the genus? The species? Binomial Nomenclature Rules Turdus migratorius

28 Binomial Nomenclature Practice You have 8 minutes!!!

29 Domain Kingdom Phylum Class Order Family Genus Species BROADEST TAXON Most Specific The major classification levels, from most general (broadest) to most specificclassification levels A group at any level is a taxon. Multiple levels are taxa.

32 Binomial Nomenclature Which TWO are more closely related?

33 The six kingdoms in the classification system are: 1. Eubacteria 2. Archaebacteria 3. Protista 4. Fungi 5. Plantae 6. Animalia

34 Dichotomous Key: a tool used to identify an organism using a series of opposite characteristics

35 Dichotomous Keys: TEKS 7.11A A dichotomous key

36 Debrief 1.What characteristics do you think separate the different kingdoms? 2.What are some things you would classify in the kingdom Fungi? Eubacteria? Plantae?

37 Dichotomous Key Search for the YouTube video “ Dichotomous Key” Dichotomous Key by Mark Drollinger Complete the worksheet using the information in the video. Due TOMORROW. http://www.youtube.com/watch?v=M51AKJqx-7s

38 Bellwork: 1/22/16 copy the question and answer choices Which of the following organisms are most closely related? A. Asterias rubens and Asterias forbesi B. Bubulcus ibis and Xenicibis xympithecus C. Ophiderma salamandra and Salamandra algira D. Ceanothus americanus and Lethocerus americanus

39 Today’s Agenda: 1. Walk around questions (15 min.) 2. Go over questions (15 min.) 3. Quiz (remainder of class)

41 1.What type of animal is Musca domestica? 2.From the table, which 2 animals are most closely related? 3. At what classification level does the evolutionary relationship between cats and wolves diverge (become different)?

42

43 4.What is the scientific name for the Canada goose? 5.Explain which two organisms are the most closely related. 6.Which taxa do the human and goose have in common?

44

45 7.At which taxon do the lion and lynx diverge? 8.Which kingdom does C. comatus belong to? 9.Which taxa do the lion and lynx have in common? 10. What is the scientific name for the lion?

46 African BuffaloBurchell’s ZebraGrant’s Gazelle Animalia Chordata Mammalia Artiodactyla Bovidae Synceruscaffer Animalia Chordata Mammalia Perissodactyla Equidae Equusburchellii Animalia Chordata Mammalia Artiodactyla Bovidae Nangergranti 11. Describe 2 conclusions that can be made from this information.

47 The mushroom sea squirt is in the same class as the common sea grape. The mushroom sea squirt is in the same family as the blue spot ascidian. The mushroom sea squirt is in the same order as the white speck tunicate. The mushroom sea squirt is in the same phylum as the starry skate. The information below describes the most specific levels of classification that the mushroom sea squirt, Sycozoa gaimardi, shares with four other organisms. 12. To which of the four organisms is the mushroom sea squirt most closely related?

48 13. Which of the beetles above must belong to the same family?

49 14. Four students researched the classifications of the following eight whales: killer whale, Orcinus orca gray whale, Eschrichtius robustus humpback whale, Megaptera novaeangliae pygmy right whale, Caperea marginata fin whale, Balaenoptera physalus minke whale, Balaenoptera acutorostrata North Atlantic right whale, Eubalaena glacialis bowhead whale, Balaena mysticetus The students were asked which two whales are most closely related and why. The table below summarizes the students’ answers. Based on the classifications, which student gave the correct answer to the question? StudentWhales Most Closely Related Reason 1killer whale and gray whale They are both mammals. 2humpback whale and pygmy right whale They are both whales. 3fin whale and minke whale They are both in the same genus. 4North Atlantic right whale and bowhead whale They are both in the same family.
