Rocks and Minerals Objectives

GRADE-LEVEL CONCEPT: u Rocks and minerals have properties that may be identified through observation and testing; these properties determine how earth materials are used.

 Describe the physical properties of rocks and relate them to their potential uses.

Relate the properties of rocks to the possible environmental conditions during their formation.

GRADE-LEVEL EXPECTATIONS:

  1. Earth is mainly made of rock.  Rocks on the earthís surface are constantly being broken down into smaller and smaller pieces, from mountains to boulders, stones, pebbles and small particles that make up soil.
  2. Rocks can be sorted based on properties, such as shape, size, color, weight or texture. 
  3. Properties of rocks can be used to identify the conditions under which they were formed.
  4. Igneous rocks are formed when melted rock cools, hardens and forms crystals.  Melted rock that cools slowly inside a volcano forms large crystals as it cools.  Melted rock that cools rapidly on the earthís surface forms small crystals (or none at all).
  5. Sedimentary rocks are formed underwater when small particles of sand, mud, silt or ancient shells/skeletons settle to the bottom in layers that are buried and cemented together over a long period of time.  They often have visible layers or fossils.
  6. Metamorphic rocks are formed when igneous or sedimentary rocks are reheated and cooled or pressed into new forms.  They often have bands, streaks or clumps of materials.
  7. Rock properties make them useful for different purposes.  Rocks that can be cut into regular shapes are useful for buildings and statues; rocks that crumble easily are useful for making mixtures such as concrete and sheetrock.
  8. All rocks are made of materials called minerals that have properties that may be identified by testing.   Mineral properties include color, odor, streak, luster, hardness and magnetism.
  9. Minerals are used in many ways, depending on their properties.  For example, gold is a mineral that is easily shaped to make jewelry; talc is a mineral that breaks into tiny grains useful for making powders.
