Mineral identification lab answers. Mineral Identification Lab In this lab you will use the physical properties of minerals to identify them. In the first part of the lab you will review the common physical properties used for mineral identification. Next you will use the physical properties of 6 unknown samples with a set of flowcharts to make the identifications.
Terms in this set 16 Calcite 1 Comes in many white colors. 3 directions of cleavage not at 90 degrees. Bryan Alonso Mineral Identification Lab Answer Sheet Type in the correct answers.
Part 1 Mineral Property Answer 1. What is the Color of this mineral. Mineral ID Kits for each station as listed below.

Identification Mineral identification is a process of elimination based on determinations of physical properties. In this activity you will use an identification key for the minerals that you described above. To use a key to identify minerals you will be given a series of choices about the properties of a mineral.
For most of the identification process the choices will be either this or that. The interactive 3-D models of the actual lab mineral samples were created using an ordinary camera and Agisoft Metashape Pro 3-D photogrammetry software. Using from 72 to 144 overlapping photos for each mineral specimen the software calculates the detailed topography of the mineral using stereographic techniques and then overlays that 3-D geometry with a composite.
Mineral Key Use the following steps to identify a mineral. Decide if the mineral is metallic or non-metallic based on its luster and streak. If the mineral is non-metallic decide if it is light or dark in color.
Find a mineral in the list with the same density and hardness as your sample. In this virtual investigation you will identify minerals by observing and testing their physical properties. After gathering data for an unknown mineral you will refer to an identification chart to determine the minerals identity.
Examine the mineral for areas where the mineral is broken. Describe the breakage as either irregular or conchoidal has the appearance of broken glass Hardness. Resistance to scratching or abrasion.
Use minerals of known hardness from the Mohs Hardness Kits. Scratch the unknown mineral with a known hardness to determine which mineral is harder. Lab 9 - Mineral Identification All rocks are composed of one or more minerals.
In order to be able to identify rocks you have to know how to recognize those key minerals that make of the bulk of rocks. By definition any substance is classified as a mineral if it meets all 5 of the criteria below. For each unknown mineral identify the key physical characteristics.
Using your Earth Science Ref-erence Tables and the Mineral ID Kits determine the name of the mineral based on the observed characteristics. Leigh-Manuell - 1 Lab Activity. _____ Minerals and Rocks.
Once the lab starts I give them the flowchart and the mineral kits to work with so they should be testing and identifying minerals simultaneously. Once the students have performed the tests on the mineral they use the flowchart to identify it and. Read the handouts first so the diagnostic features are fresh in your mind.
On the blank charts provided fill in all the physical properties for the suite of mineral specimens supplied in the lab by making your own observations. This Mineral Key is designed and intended for use on-line. The premise behind this Key is similar to that of the identification keys found in some fern and wildflower books.
Key diagnostic properties are used to direct users to tables where further information on likely suspects is found. Other Properties Mineral White 1-Cleavage Earthy or pearly luster. Scratched Talc by fingernail Scratched by penny Yellow Brown Earthy Fracture Earthy luster yellow to almost black.
Technically not a mineral as it lacks a crystalline structure. Limonite Uses Baby powder paints ceramics Iron ore White 1. Each mineral has characteristic properties that can be used to identify it.
O Properties geologists use to help identify minerals are. O Color easy to observe but only a few minerals can be identified by color alone. Impurities can contaminate the mineral changing its color.
For example quartz can be white pink or purple. O Streak the color of a minerals powder. Use a steak plate to.
This is a lab for teachers who do not have access to a mineral or rock collection yet still need to meet outcomes requiring students to identify rocks and minerals with a classification keyAnswers included as well as student answer sheetsYou will need to find an indentification chart with color l. In addition to this a printable 22 page activity booklet contains student activities and answer keys to go along with the Interactive Rock Identification. From the table of contents students can choose rocks in any order.
The Interactive Rock ID navigates like a web site with clickable links that moves students along depending upon their responses. Identify a mineral by name based on a unique collection of properties - for example because the sample scratches glass exhibits a pattern of fracture called conchoidal and doesnt produce a streak these limited properties coincide with those of the mineral quartz as described in my textbook table - so Ill conclude that this sample is made of quartz.
