Learn how to pan for gold! Determining whether students have met the goals Upon completion of the pre-test, students should have a working knowledge of the terms for this activity.
Students answer summary questions at the end of the lab. The colors come mainly from the differences in iron and magnesium content.
Teaching Tips Adaptations that allow this activity to be successful in an online environment There is a link in the assignment for students to practice rock identification prior to identifying the samples in the photographs provided with the lab.
There are only nine minerals to check for in common igneous rocks, only some of which will be present in a given rock.
Hold the rock up to a magnifying lens to look at the minerals more closely and identify them more accurately. This gallery includes photos of sand from around the world.
These features provides essential clues Lab 2 3 igneous rock identification what occurred in the earth at the place and time that the rock formed. Igneous rocks with olivine in them are usually mafic. Pieces of this activity may be used on their own in a different setting, but access to appropriate rock and mineral samples is essential.
Soapstone Soapstone is a talc-rich rock with properties that make it suitable for a variety of projects. We study igneous rocks to be able to use them as sources of information about geological processes.
The nine common minerals likely to occur in igneous rocks are: This color rule works most of the time but there are two exceptions that you need to keep in mind. Recommendations for other faculty adapting this activity to their own course: Refer to the Lab Assignments Grading Rubric for a reminder of what constitutes a well-performed lab.
Specimens for personal or classroom use. Use your mineral identification skills to check for mineral cleavage, fracture, luster, color, hardness, crystal form, and special properties of particular minerals.
Sometimes this is called basaltic composition, but the term mafic is more appropriate. The color rule states that the more mafic the rock, the darker it is.
Igneous rocks contain three essential sources of information: You must identify the igneous texture of each rock as well. Consider what you have just read about using color and minerals to determine igneous composition, and look closely at the four photos below labeled A through D.
Rock Art Rock Art People have been producing rock art for thousands of years. Turn the rock in the light and look at it closely to see its contents and determine its texture and composition. To understand and identify igneous rocks, you cannot be shy about addressing the rocks.
Solution sets are dependent upon individual samples whether provided in photographs, online links, or physical hand samples provided to students. A digital camera that enable you to take up close, in focus photographs of rocks that are detailed enough to show their visible minerals and textures A computer on which to upload your pictures The Igneous Lab Worksheet Geology Learning Outcomes By performing and completing this lab, you will progress toward the following learning objectives for this course: I intend to use this online exercise in my course this fall for students in my face to face class to test.
They also examine key metamorphic minerals and infer the metamorphic conditions under which they are stable based on their observations of the rocks.
Geology Tools Geology Tools - Hammers, field bags, hand lenses, maps, hardness picks, gold pans. Intermediate igneous rocks tend to have intermediate shades or colors green, gray, brown, equally mixed salt and pepper. Do not be shy about using the hand lens and microscope.
Tumbled Stones Tumbled Stones are rocks that have been rounded, smoothed and polished in a rock tumbler. In a face to face class, the instructor will provide the rock samples to identify. Quartzite Quartzite a nonfoliated metamorphic rock composed almost entirely of quartz.
The second exception to the color rule is that igneous rocks exposed to air and water for a long time undergo weathering, which changes their color. It is the source of all igneous rock.
Igneous Rock Classification Table page will open in new window Introduction Magma is molten rock inside the earth. Images, code, and content on this website are property of Geology. Remember what you learned in the minerals lab - you have to do more than look at the samples.
Caliche Caliche is a lithified layer in soil or sediment. The class size can vary, but is usually students working in groups of people.Unit 2 Managing Paediatric Illness and Injury Level 2 1.
Describe the common types of fractures and how to manage them. Broken bone. Based on the location and severity of the fracture, a broken bone usually must be set into position and supported until it is strong enough to bear weight. A. Identifying the Various Igneous Rock Types: Identification of unknown igneous rock samples are done utilizing a simple step-by-step procedure outlined in Figurepage 92 in your Lab manual.
Page - Lab 4 - Identification of Igneous Rocks Introduction A rock is a substance made up of one or more different minerals. Thus an essential part of. LAB 4: TEXTURES AND IDENTIFICATION OF SEDIMENTARY ROCKS OBJ ECTIVS 1) to become familiar with the properties important in recognizing and classifying sedimentary rocks.
Lab # 8 - Igneous Rock Identification Lab Introduction: The type of igneous rock formed when molten magma solidifies depends on the mineral composition and the rate at which the magma cools. Nov 24, · Planet Earth-Lab 2-Igneous Rocks - Duration: RNEarthSciences 19, views.
