Florida SC.4.E.6.2
The Standard
Identify the physical properties of common earth-forming minerals, including hardness, color, luster, cleavage, and streak color, and recognize the role of minerals in the formation of rocks.

What This Standard Means
What Students Need to Do
- Students examine mineral samples and gather evidence with scratch tests, streak plates, reflected light, and break patterns. They explain that rocks are made from one or more minerals.
What Mastery Looks Like
- Students distinguish surface color from streak color and correctly describe hardness, luster, and cleavage. They use several observations to identify an unknown mineral and explain how minerals combine in rocks.
Common Misconceptions
- Students may identify a mineral by color alone or assume its streak always matches its surface. They may confuse hardness with resistance to breaking, or mistake any broken edge for cleavage.
How to Assess It
- Give students a mineral property chart and observations for one unknown sample. Ask them to name the mineral, cite two supporting properties, and explain its connection to rocks.

Ways to Teach It
At stations, students test quartz, calcite, mica, and talc with fingernails, pennies, streak plates, and flashlights, then record evidence.
Ask students to write: Why can two minerals look alike but leave different evidence during identification tests?
Play Mineral Detective: teams match mystery sample cards to a property chart and earn a point only when they cite two observations.
Inspect granite countertop or tile samples, identify visible mineral grains, and list ways those minerals affect color, shine, or durability.
