This document is a completed lab assignment for Liberty University’s Elements of Earth Science (PHSC 210) course, specifically focused on sedimentary rock identification. It represents a student’s work submitted on October 14, 2020, by Ava Philbrok.
This lab is designed for students learning introductory Earth Science and needing to practice identifying rocks based on key characteristics. It’s typically used as a hands-on component of a larger sedimentary geology unit. The assignment exists to assess a student’s ability to apply learned concepts to real-world samples.
This completed assignment serves as an example of how to approach the lab, including sections for stating the purpose, hypothesis, data collection, observations, analysis, and application of knowledge. However, it does *not* provide instruction on *how* to identify the rocks – it simply demonstrates one student’s process and results.
The full document includes a completed data table identifying various sedimentary rocks (limestone, shale, sandstone, conglomerate, siltstone, breccia, coal) based on texture, grain size, hardness, and composition. It also contains the student’s observations, analysis of the exercise, and an application scenario. This preview *does not* include the original rock samples, the clastic/chemical sedimentary rock charts, or the Mohs Hardness Scale used in the lab.
