Please write your Answers using bold or italic letters - it will really help me grading VIII. Conclusion: A one sentence statement as to whether you achieved the purpose or not. Lab Reports should always include I, II, III, VII, and VIII. They may be submitted electronically by attaching them to the assignment box. They must be done with MS WORD.

Lab # 2 (Summer ’17 version) —Earth Science Mineral Identification—Part I and Part II Purpose: To learn various properties of minerals and how to identify the major mineral groups and specific minerals using these properties.

Introduction: This lab uses the GEODe program which is found at the following website (You will need to buy an access code). Minerals are solids with an orderly arrangement of atoms formed by inorganic processes. They have definite chemical compositions and recognizable physical properties. Complex instrumentation and chemical procedures are used to identify some minerals. We will use physical properties that are easily recognized to identify some of the most common minerals.

In this lab, we will examine the definition of a mineral, the main groups of minerals, the properties of minerals, and the identification of minerals. This lab is presented in two parts. Both parts need to be investigated to complete this lab. Procedure: 1) Read the rest of the information on this exercise before starting the lab. 2) Print this page to refer to while using the Pearson Mastering Geology/Mastering Oceanography GEODe program.

3) Go to the following website and login. Login is as follows: Login: [email protected] Password: Pilar) Click on the tab at the top labeled “ Study Area .†Look along the left-hand side of the screen and click on the GEODe Earth Science link. 5) Under Unit I EARTH MATERIALS, click on the A. Minerals link. 6) Navigate through the program and answer the questions below as you go.

Remember, you can back up and repeat at anytime. This lab covers most of Frames 1-117, so stop when you get to Frame 117. 7) Remember to submit your lab report in the proper format under the “Lab Assignments†tab within Blackboard. Questions – PART 1: 1) What is the main mineral ingredient found in cosmetics? 2) What 3 minerals are found in granite (a rock)?

3) Using the definition of a mineral, determine whether or not the following substances are minerals. If it is a mineral, answer “Yes, this is a mineral.†If it is NOT a mineral explain why it is not by answering, “No, this is not a mineral because...†and provide the reason. a) gold b) synthetic diamonds c) quartz d) petroleum e) animal bone f) ice g) granite h) steel 4) What is the most common group of rock-forming minerals? SKIP FRAMES ) Name a silicate with low silicone content. 6) Name a silicate with high silicone content. 7) What determines the cleavage exhibited by silicates?

8) What is the cleavage difference between mica and quartz? 9) What are two major groups of the silicates? Name 2 minerals in each group. 10) Carbonates are a second rock-forming mineral group. Give two examples.

Paper For Above instruction

The process of preparing a comprehensive earth science lab report involves systematic documentation of the experiment's purpose, methodology, observations, calculations, results, and conclusions. This paper will exemplify how to craft such a report focusing on the mineral identification lab, integrating the specified content for clarity and coherence.

Introduction

The mineral identification laboratory is designed to familiarize students with the physical properties that define and distinguish minerals. Using the GEODe program, students analyze mineral properties such as luster, streak, cleavage, hardness, and crystal form to accurately identify various minerals. Understanding these properties helps students grasp fundamental geological concepts and develop practical skills for mineral identification in field and laboratory settings. This introductory section emphasizes the importance of physical properties in mineral identification and sets the foundation for subsequent detailed analysis.

Purpose

The primary purpose of this lab is to learn and apply the physical properties of minerals to accurately identify major mineral groups and specific minerals using the GEODe program. Through this exercise, students will understand the significance of properties such as luster, cleavage, hardness, streak, and crystal form in mineral identification.

Procedure

Students are instructed to access the GEODe program via the Pearson Mastering Geology platform, logging in with provided credentials. The exercise involves navigating through the program, answering questions related to mineral properties, and identifying minerals based on visual and physical criteria. The lab is divided into two parts, each requiring prior reading and understanding of mineral properties, followed by interactive examination within the software. The process emphasizes observational skills, interpretation of physical properties, and documenting results with clarity.

Data and Observations

Data collected include mineral properties such as luster, streak color, cleavage planes, hardness, and crystal form. Observations also involve recording the identification and classification of minerals, noting specific features such as fracture styles and specific gravity where applicable. These data are essential for accurate mineral identification, as they form the basis for analysis and conclusions.

Sample Calculations

In cases where calculations are necessary, such as determining specific gravity or hardness, work should be shown clearly. For example, if measuring density, the formula used (mass divided by volume) and calculation steps are documented to substantiate the identification process.

Results

The results section compiles identified minerals, their properties, and the rationale behind their classification. This includes the confirmation of mineral identities through properties such as the number of cleavage planes, crystal form, and Mohs hardness. Results also involve decisions based on observed physical criteria, reinforcing the identification process.

Questions and Answers

This section reflects the understanding gained from the late analysis. Questions such as "What is cleavage?" are answered comprehensively, with detailed explanations supported by observations. Important answers are emphasized using bold or italics, making assessment straightforward.

Conclusion

The conclusion succinctly states whether the purpose of identifying minerals based on physical properties was achieved. It confirms the ability to correctly identify minerals using the GEODe program and physical property analysis, thus validating the learning objectives.
