4C Rocks and Minerals KWL Chart K (Know)W (Want to Know) Different types of minerals and rocks Minerals are found underground Minerals can be more valuable than rocks Possible mineral examples: diamond, emerald, topaz, quartz, mica, feldspar, ampitite, obsidian, gold, ruby, sapphire Possible rock examples: granite, diorite, andesite Minerals can have different colored streaks Minerals and rocks can come in different shapes and sizes Can diamonds break? Are gems rocks or minerals? Do rocks and minerals form in the same conditions? Can minerals be poisonous? How are minerals made? Can rocks be minerals? Can minerals be rocks? What are rocks made up of? Where can you find minerals? Can minerals be found in the air and water? Can rocks and minerals help us? Which is more important: rocks or minerals?

4D Rocks and Minerals KWL Chart K (Know)W (Want to Know) Dug from underground Rocks go through the rock cycle Some rocks can bend Different types of rocks and minerals Some minerals can be very valuable Rocks are solid and hard, can contain minerals Both are natural and nonliving things Types of rocks: igneous, metamorphic, sedimentary Some rocks have interesting properties (ex. Can float) Types of minerals: diamonds Diamonds are the hardest mineral Different sizes Can be used to make tools Can be dull or shiny Volcanoes can form rocks Rocks can be found everywhere! What is the largest rock in the world? How many types of rocks and minerals are in the world? Can be rocks be used to make future technology? How do rocks form? Can rocks change into different types? Do all rocks come from the ground? Do all minerals contain rare materials? Do metamorphic rocks have more elements? Can rocks melt? How many rocks are in the ocean? Can diamonds break? Can rocks have different colors? Are comets and meteors rocks? Why are rocks and minerals important?

4A Rocks and Minerals KWL Chart K (Know)W (Want to Know) Minerals are found underground or in rocks Rocks and minerals are nonliving things Made by pressure underground Minerals can be different colors Types of rocks: sedimentary, igneous, metamorphic Obsidian (lava rock and water) Rocks can contain minerals Types of minerals: diamonds, salt, emeralds, amethyst, gold, silver, sapphire Diamonds are strong minerals Some rocks can float (pumice) Can minerals be broken? How are rocks and minerals formed? How hard are rocks? (bedrock) Can minerals and rocks become liquid? What is the rarest rock in the world? What is the rarest mineral in the world? How do rocks form in a particular shape? Is a mineral a type of rock? Which is harder: diamond or obsidian? Is red stone a rock or mineral?

4B Rocks and Minerals KWL Chart K (Know)W (Want to Know) Rocks can be in different sizes Three types of rocks: igneous, sedimentary, metamorphic Bigger rocks are called boulders, smaller rocks are called pebbles Minerals and rocks can be found on other planets Rocks can come together to form other things (ex. pearls) Rocks are nonliving things Rocks have salt in them that go into the ocean through rivers Plants use minerals in the soil People mine for minerals Rocks and minerals are found in Earth and under the ground Rocks are natural resources If you add heat to sand you can create glass Possible types of minerals: metal, Rocks can come from volcanic eruptions Example: obsidian How are minerals made? What are they made of? What are minerals used for? What can you make with them? How are minerals different from rocks? Can you eat minerals? What are rocks made of? Can minerals make water dirty like rocks? Can minerals contain salt? How many types of minerals and rocks are there? Why do we mine for minerals? How far down do we need to dig to find minerals? Do minerals and rocks affect nature?

Minerals and Rocks Unit Overview We will… Discover what minerals are and where they can be found Use physical properties to identify minerals Learn about fossils and how we can use them to understand the past

Targets & Warm Up Targets: Students will discover what minerals are and where they can be found Warm Up: None

Exploring Rocks and Minerals (7 minutes) Questions to consider: What is a rock? What is a mineral? What are the differences between rocks and minerals?

Minerals

Natural, nonliving solid crystals that make up rocks Each mineral has crystals that are a particular shape

Minerals Scientists have identified over 3,000 minerals Most of the rocks in the Earth’s crust are made from only a small number of minerals

Minerals Most rocks are made of different combinations of minerals – Ex. Granite  Quartz & Feldspar A few other types of rock consist of only one or two materials – Ex. White marble  Calcite

Granite rock Quartz Feldspar

White marble rock Calcite

Rocks and Minerals Video (4 minutes) Questions to consider: What are minerals and rocks? How do minerals become rocks?

Mineral Observation Your task: 1.Observe the different minerals – You may use your eyes & hands – You may use hand lenses to see the minerals in more detail 2.Compare their similarities and differences 3.Discuss what scientists might do to identify the different minerals
