Part 1: Learning about Scientific Names
Explain that every plant and animal has its own scientific name. Scientists around the world recognize this name, regardless of which language they speak. The scientific name has two parts to it. The first part is the genus name, which is always capitalized. The second part is the species name, which is always written in lower case. Organisms that share the same genus name are closely related. Organisms with similar species names may share common features, such as shape or color. The species name usually describes something about the organism, the person who discovered the organism, or the location where the organism was first observed. The scientific name is usually made up of words that come from either Latin or Ancient Greek.
Distribute copies of the Greek and Latin word fragment sheet. Point out that the word fragments that have a hyphen at the beginning are suffixes. Those that have a hyphen at the end are prefixes. The words are sometimes used by themselves, or with a suffix or prefix.
Explain that the scientific name for the North Atlantic right whale is Eubalaena glacialis (you-buh-LEE-nuh glay-see-AL-liss). Write this name on the board. Explain to the students that these words come from one Greek word and two Latin words (also referred to as "roots"). Have the students look on the sheet for the words (eu, balaena, and glacialis) and ask them what each one means.
a. eu = true
b. balaena = whale
c. glacialis = frozen
So, a literal translation of this name would be "frozen true whale" (probably because it can be found in very cold waters).
4. Explain that the scientific name for the short-finned pilot whale is Globicephala macrorhynchus (GLOW-bih-SEF-al-lah MA-cro-rink-us). Write this name on the board. Show the students that these words come from three Greek roots and one Latin root. Have the students look on the sheet for the words (glob, cephal, macro, and rhynch) and ask them what each one means.
a. glob = globe, ball
b. cephal = head
c. macro = large
d. rhynch = beak, snout
So, a literal translation of this name would be "large snout ball head." Show students a picture of a short-finned pilot whale (page 5-5) and explain how the scientific name is a good descriptor for this whale (it has a ball-shaped head and a large beak).
5. Ask the students to use the list of Greek and Latin word fragments to help decipher the following scientific names. Show them images of the whales.
a. Balaena mysticetus (bay-LEEN-uh miss-tih-SEE-tuss): bowhead whale [whale mustache whale]
b. Balaenoptera musculus (bay-leen-OP-ter-rah MUSK-you-luss): blue whale [muscle/muscular winged whale]
c. Tursiops truncatus (TUR-see-ops trunk-AH-tuss): bottlenose dolphin [porpoise appearance provided with a trunk]
d. Ziphius cavirostris (ZIFF-ee-us cah-vee-OSS-triss): Cuvier's beaked whale [hollow daughter of snout sword]
Part 2: Create an Imaginary Cetacean!
Distribute the Greek and Latin word fragments and meanings sheet.
Explain to students that they are going to invent and produce a model of an imaginary cetacean, and that they will be using the word fragments to create a scientific name that describes their whale or dolphin.
Encourage students to create the scientific name first. Remind them that there are two parts to the scientific name, and that each part can contain a single word fragment or two or more word fragments in combination. The first word (genus) should begin with a capital letter; the second word (species) should begin with a lowercase letter. The scientific name should be italicized or underlined.
Once the students have created a scientific name, they should draw or use other artistic media (sculpting, papier-mâché, painting, etc.) to create a picture or model of their cetacean. They should write the scientific name of their whale (along with the translation) on their picture or create a label for their model.
Distribute Cetacean Information sheets to students. Have students pretend they are marine biologists who have discovered the cetaceans in step 2. Encourage students to be creative when filling out the imaginary information on this sheet. Students will use this information as the basis for a newspaper article describing the discovery of their cetacean and providing information about its life history.

What is the scientific name of your cetacean (2 words)?
What is the English translation of this scientific name?
Where does your cetacean live (in what ocean or oceans, near shore, in very deep water, etc.)?
How big is your cetacean (remember to include the units for length and weight)?
Does your cetacean migrate, or live its entire life in one region?
Does your cetacean have any special color patterns? What are they?
Is there anything special about your cetacean's size, body shape, fins, etc.? If so, what?
What does your cetacean eat?
Does anything eat your cetacean?
Use the information above as the basis for a newspaper article. You will write the newspaper article as though you are a marine biologist who has just discovered the cetacean you have described. In the article, you should be creative in describing the animal, its habitat, and its life history. You can also describe the voyage during which you discovered the animal. Your article should contain at least three paragraphs (introductory, body, and concluding).
