Learn on PengiEarth Science (Grade 6)Chapter 2: Minerals

Lesson 3: Minerals are valuable resources.

In this Grade 6 Earth Science lesson from Chapter 2: Minerals, students explore how minerals such as quartz, feldspar, fluorite, graphite, and corundum are used in everyday industrial products and decorative arts including jewelry and gemstones. Students also learn how minerals form from magma and lava, how they are extracted through mining, and examine the trade-offs involved in the mining process. The lesson connects classroom mineral identification skills to real-world applications, helping students recognize minerals in familiar items like toothpaste, paint, glass, and pencils.

Section 1

Minerals Form Through Natural Processes

Minerals develop when atoms join together to form crystals. They can form when water evaporates, hot water cools, molten rock solidifies, heat and pressure change existing minerals, or organisms produce them naturally.

Section 2

People Extract Minerals Through Mining Methods

Miners use surface methods like panning, strip mining, and open-pit mining to extract minerals near Earth's surface. Deep mining involves digging passages to reach valuable ores located underground or within mountains.

Section 3

Industries Transform Minerals Into Useful Products

Minerals provide essential materials for modern life. Quartz creates glass, hematite yields iron for machines, gibbsite produces aluminum for cans, and galena supplies lead for batteries and weights.

Section 4

Artisans Shape Gemstones for Decoration

Gem cutters transform rough minerals into beautiful gemstones by grinding them into desired shapes and polishing them. Hard minerals like diamond and corundum are used to shape softer gemstones.
