Student Name : Insert Your Name Here TA Name : Insert Your TA’s Name Here Rubric – Fall ‘22 Now that you have completed the investigation, it is time to synthesize (bring together) all the data and observations you have made to create an essential understanding to the guiding question posed at the beginning of the investigation: How are observable traits used to interpret the depositional environments for sedimentary rocks and protoliths of metamorphic rocks? The lab write-up is a summative assessment to evaluate how well you have developed the scientific skills and concepts outlined throughout the investigation. The following questions are built to help you create a scientific argument. Think of this as an outline to creating a scientific argument paper. Answer each of the following questions with a thoughtful and thorough paragraph in your own words. 1. Claim : Create a 2-3 sentence answer to the guiding question above. The short paragraph should directly answer the guiding question and utilize concepts and vocabulary based on what you have learned from the introductions, the data/observations, and your lab discussion. HINT : Do not simply restate the guiding question! Insert Answer Here 2. Evidence Descriptions : In 3 or more sentences, directly describe the defining traits for o Sedimentary sample ( Sample #15 ) that can include:  Grain type  Range of grain sizes/sorting/angularity  Reaction to HCl  Other defining traits and observations  The sedimentary rock name o Metamorphic sample ( Sample #20 ) that will include:  Texture  Crystal size  Other defining traits and observations  The metamorphic rock name Insert Answer Here 3. Interpretation & Justification : In 4 or more sentences, explicitly discuss how the data/observations from Question #2 directly supports the claim you created in Question #1. HINT : o Provide your interpretation of the energy and depositional environment for sedimentary sample ( Sample #15 )  Justify your answers by discussing what observations from question #2 lead you to the interpretation. o Provide the metamorphic grade and potential protolith of metamorphic sample ( Sample #20 ).  Justify your answers by discussing what observations from question #2 lead you to the interpretation. o Think about what definitive features of the rock samples were clues to lead you to the interpretation! Insert Answer Here 4. Real-World Issues : Reflect on the process of identifying sedimentary/metamorphic rocks and interpreting their formation history . Choose one of the articles linked below that interests you. Skim the article and discuss in 2-3 sentences how the concepts/skills that you learned from the investigation are being utilized to understand a region and/or to advance/protect/affect local and global communities. Do not simply summarize the article. Sedimentary & Metamorphic Rocks EaES 111 – Fall 2022 1
