What This Document Is
This document is a lab exercise and accompanying questions for GEL 111, a Geology course at Coastal Carolina Community College. The lab focuses on the concept of density and its application to understanding the internal structure of planets, specifically Earth. It involves calculating densities of unknown rock samples and applying those calculations to model planetary composition.
Why This Document Matters
This lab is crucial for students in GEL 111 as it provides practical experience applying the fundamental scientific principle of density. Understanding density is key to interpreting geological data and modeling the Earth’s layers – and by extension, the layers of other planets. It’s likely used as a foundational exercise early in the course to build quantitative skills and conceptual understanding. Students will use this knowledge in subsequent labs and lectures dealing with Earth’s composition and structure.
Common Limitations or Challenges
This document provides a guided exercise with specific data. It does *not* cover the broader theoretical background of density calculations beyond what’s needed for the lab itself. It also doesn’t explore advanced applications of density in geological research, such as isostasy or mantle convection. Students will still need to understand the broader context of these concepts through lectures and readings.
What This Document Provides
This lab includes: pre-lab questions to assess prior knowledge of Earth’s layers, data sheets for recording measurements of mass and volume for unknown rock samples, post-lab questions requiring density calculations (using the formula p=M/V), and application problems relating density to planetary structure and buoyancy. Specifically, it provides worked examples of density calculations for two unknown rocks, and a problem applying density to determine how much of a wooden block and a section of continental crust would be submerged in water or the mantle. This preview *does not* include the full set of data tables, all post-lab questions, or the complete solutions to all problems.
