TCT (Through- Course- Task)_Bio_2 Grades 9-10 Standards DCI: LS1.C - The sugar molecules thus formed contain carbon, hydrogen, and oxygen: their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins or DNA), used for example to form new cells. (HS-LS1-6) Crosscutting Concepts: Patterns: students observe patterns in systems at different scales and cite patterns as empirical evidence for causality in supporting their explanations of phenomena SEP: Analyzing and Interpreting Data : Compare and contrast various types of data sets to examine consistency of measurements and observations; Evaluate the strength of a conclusion that can be inferred from any data set Storyline: Amelia and Jalaya are examining structures of various molecules in a chemistry lab. They come across 2 unmarked molecules which they called, “Molecule X” and “ Molecule Y.” Amelia is not sure whether the 2 unmarked molecules are organic or inorganic. Jalaya hands her the data that they have compiled shown below. Amelia’s Conclusion Amelia says that Molecule “X” is inorganic because it does not have carbon while Molecule “Y” is organic because it has carbon and oxygen based on the data. The organic molecules from the data all have carbon. Task: Write a Claim- Evidence- Reasoning evaluating Amelia’s claim in correctly identifying Molecules X and Y as organic or inorganic. Make sure to have a concise and focused claim. In addition, include evidence from both the organic monomers and polymers as well as inorganic molecule data below. Finally, reason why your evidence supports your claim using patterns in the data, facts, terms, and other background knowledge.
