1 ) Write arguments focused on discipline-specific content.

a. Introduce claim(s) about a topic or issue, acknowledge and distinguish the claim(s) from alternate or opposing claims, and organize the reasons and evidence logically.

b. Support claim(s) with logical reasoning and relevant, accurate data and evidence that demonstrate an understanding of the topic or text, using credible sources.

c. Use words, phrases, and clauses to create cohesion and clarify the relationships among claim(s), counterclaims, reasons, and evidence.

d. Establish and maintain a formal style.

e. Provide a concluding statement or section that follows from and supports the argument presented.

[SC2015] LSC7 (7) 16 :

16 ) Construct an explanation based on evidence (e.g., cladogram, phylogenetic tree) for the anatomical similarities and differences among modern organisms and between modern and fossil organisms, including living fossils (e.g., alligator, horseshoe crab, nautilus, coelacanth).

The lesson will begin by students accessing their prior knowledge of the anatomical similarities and differences among modern and fossil organisms by creating a Venn diagram with a partner, which will compare and contrast two organisms. Next, students will complete the online modules found at "What did T. rex Taste Like?" from the University of California Museum of Paleontology, which will explain how a cladogram diagram can be used to show lines of lineage and evolutionary relationships. Students will use a cladogram to infer how a T. rex is related to modern organisms. Lastly, students will construct a written explanation to describe the anatomical similarities and differences between the T. rex and modern organisms based on evidence from the cladograms in a claim-evidence-reasoning format.

This lesson will require students to research the three tenets of cell theory and describe the scientific evidence that supports this theory. After students complete their research, they will engage in all steps of the writing process, including prewriting, outlining, revising, and editing. At the conclusion of the lesson, students will create a three-paragraph argumentative essay to examine the cell theory and the scientific evidence that supports this theory.

10 ) Use evidence and scientific reasoning to explain how characteristic animal behaviors (e.g., building nests to protect young from cold, herding to protect young from predators, attracting mates for breeding by producing special sounds and displaying colorful plumage, transferring pollen or seeds to create conditions for seed germination and growth) and specialized plant structures (e.g., flower brightness, nectar, and odor attracting birds that transfer pollen; hard outer shells on seeds providing protection prior to germination) affect the probability of successful reproduction of both animals and plants.

4 ) Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to Grades 6-8 texts and topics.

At the beginning of the lesson, students will view an engaging video of time-lapse photographs of flowers blooming, and students will create a T-chart listing the similarities and differences among the appearances of each flower. To formatively assess students' current knowledge of specialized plant structures, the students will sort key vocabulary words related to plants' structures into categories. Then, students will read an informational article on flowering plants and re-sort the key vocabulary words into the correct categories to demonstrate their knowledge of plants' specialized reproductive structures. Next, students will complete a lab activity in which they will carefully dissect a flower and observe the various specialized structures, collect specimens to view under the microscope and create and label scientific sketches of the flower's specialized structures. Lastly, students will design a unique flower that will have a high probability of reproductive success and provide a written response in a claim-evidence-reasoning format.
