6.6: Matter and Energy. The student knows matter has physical properties that can be used for classification. Supporting Standard: C - Test the physical properties of minerals, including hardness, color, luster, and streak. Process Skills Connection: Has been tested with (but not limited to): 6.2.C collect and record data using the International System of Units (SI) and qualitative means such as labeled drawings, writing, and graphic organizer

Common Misconception:

Key Concepts: ● There are over 2,000 identified minerals on Earth. ● Minerals are naturally occurring, inorganic solids, with a definite chemical composition. ● Minerals are used in cements, mortars, making glass, electrical equipment, and many other things in our everyday life. ● Minerals can be categorized by analyzing their physical properties such as color, hardness, or luster. ● Mohs scale numbers provide a reference for the hardness of a mineral. Low numbers indicate a softer mineral and high numbers a harder mineral. ● Hardness can be tested using objects of known hardness such as fingernail, penny, iron nail, or piece of glass. ● If an object is able to scratch the mineral, the mineral is softer than the object. ● Luster describes how a mineral appears to reflect light. It refers how shiny or dull the mineral appears. ● Minerals come in various colors, some of which are vibrant and others dull. ● The color of a mineral depends on the chemical composition. ● The color of a mineral can vary, so it should be used in conjunction with other physical properties when identifying minerals. ● The color of a mineral when it is powdered is called the streak of a mineral. ● A streak test is conducted by rubbing the mineral across a streak plate and examining the color of the line left behind. ● The color of a mineral and the streak of a mineral are not always the same. 5E Lesson Template, June 2014 mw

● Rocks are made from combinations of different minerals. Guiding Questions ● What are minerals? (naturally occurring inorganic solids that have a set chemical composition) ● What are physical properties? (properties of matter that can be observed without chemically changing the substance) ● Describe luster. (answers will vary) ● Which is the hardest of all minerals? (diamonds) ● What information can be found on the Mohs scale? (relative hardness) ● Why is color not always helpful in identifying a mineral sample? (some minerals come in a variety of colors) ● Describe a streak test. (rubbing a mineral across a smooth surface so that it leaves a trail of powder behind) ● How would you test a mineral sample for identification? (answers will vary) ● What resources are helpful in the identification of minerals? (Mohs scale and other mineral charts and identification information)

Intervention: ● Show the video clip from BrainPop http://www.brainpop.com/science/earthsystem/mineralidentification/preview.weml ● Provide samples of minerals for students to test and explore. ● Adapted text for note taking assistance

Enrichment: ● Pre-AP – LTF – Minerals Mystery Challenge students with the Know-Whin Investigation scenario at http://academic.brooklyn.cuny.edu/geology/leveson/core/linksa/mineral_invest_intro.html

Students should be able to answer questions like the following: A student wants to group the minerals in his collection based on their luster. Which of the following classifications should he use? A fracture or cleavage B blue or green C shiny or dull D hard or soft Samantha needs to identify a mineral sample, so she performs a scratch test on the sample with an iron nail. What property of the mineral is she testing? A color B streak C cleavage D hardness A student is conducting an investigation of a mineral sample. He finds that the mineral is harder than apatite, but is softer than a diamond. Which of the following could NOT be the mineral the student is working with? A corundum B quartz C topaz D fluorite 5E Lesson Template, June 2014 mw

A classmate shows you a sample of a mineral he has found outside. What evidence can you use to support that this sample is a mineral?

Answer Key: C, D, D, Sample open ended answer - Check to see that the sample follows the definition of a mineral. A mineral is formed by nature, it is inorganic (not living), solid with a chemical formula and arranged in a crystal form.
