EaES 111 - Inv. 07 - Interpreting Rock Sequences - Lab Write-Up - Fall 2022 (1)

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 can Earth scientists reconstruct the geologic history of a region? 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 samples B , C , H , and J , providing:  The relative age sequence of the rock layers from oldest to youngest  The rock type (igneous, sedimentary, or metamorphic)  Qualitative observations of each sample  The rock name  The interpretation of formation 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 : Now put together the rock names, interpretations, and relative age sequences of layers B , C , H , and J to conclude: o Does the geologic history of this area demonstrate a Transgression or a Regression?  Define a transgression/regression, depending on how you interpret the sequence o Justify your answers by connecting your observations/interpretations of the layers to the definition of transgression/regression (how your observations lead you to your conclusions)  SECOND HINT : Revisit Figures 06 & 07 of the introduction Insert Answer Here 4. Real-World Issues : Reflect on how scientists interpret sequences of rock to create a geologic history and the importance of this skill . 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. o Eruption in El Salvador Was One of the Holocene’s Largest o Indonesian Cave Reveals Nearly 5,000 Years of Tsunamis o Insights into the Habitability of Mars Insert Answer Here 5. Lab Notes : Insert a photograph of pages ( 7-7 and 7-11 ) from your lab manual. For each photo, make sure: Interpreting Rock Sequences EaES 111 – Fall 2022 1
