Friday, Nov 2nd • CW: Rock Types and Rock Cycle • HW: NONE • Warm-up • Why is it important to identify different properties of minerals? • How can we use this information? • Materials: – – – – – Pencil Warm-up Agenda Gluestick Lab notebook *BACKPACKS on the side! Take out lab notebook!! • Label table of contents (2min) & glue in: – Rock Type notes – Rock cycle Rocks There are many kinds of rocks. They come in a great variety of shapes, sizes, colors, and textures. Rocks also have some things in common. They are made naturally and are made of smaller particles and minerals that are stuck together. They are made of specific chemicals. What do rocks have in common? a. They are all the same size b. They are all the same color c. They are made naturally d. They are the same shape Factories use different processes to make things. They use heat, water, and force from machines to form their products. Earth is like a giant rock factory. Wherever you are right now, if you could dig down far enough, you would find rocks being made deep inside the earth. 2. How is the Earth like a factory? a. b. c. d. They both have machines They both use the same process They both make rocks They both make things Rocks can be divided into three rock types. They are igneous, sedimentary, and metamorphic. The groups describe how they are made. 3. Rocks are divided into which three groups? a. igneous, sediment, metamophose b. sedimentary, igneous, metamorphic c. ignite, metamorphic, sediment d. sedimentary, ignite, metamorphic • TSW understand the evidence that shows the Earth has changed over geologic time (including the types of rocks, the rock cycle, minerals, and fossil record). • 4 In addition to score 3, the student can help teach or mentor his/her peers. • 3 TSW understand the evidence that shows the Earth has changed over geologic time (including the types of rocks, the rock cycle, minerals, and fossil record). • 2 TSW understand the evidence that shows the Earth has changed over geologic time (including 2 of the 4 requirements): – – – – Types of rocks The rock cycle Minerals The fossil record *1TSW understand the evidence that shows the Earth has changed over geologic time (including 1 of the 4 requirements):Types of rocksThe rock cycleMinerals, andThe fossil record *0Even with help, the student experiences no success. Igneous •These rocks were made from cooled magma or lava •Igneous literally means “From Fire” http://www.learner.org/interactives/rockcycle/change2.html • The texture depends on how fast the rock cools – Quickly cools- smooth texture – Slowly cools- bumpy or rough texture Sedimentary http://www.learner.org/interactives/rockcycle/change3.html These rocks are made from layers of sediment that has been cemented together Types of sediment: • They are soft and crumbly, made of layers • Examples are sandstone, limestone and shale sand, shells, pebbles, bits of rock, minerals, organic matter (from living things), or fossils Metamorphic http://www.learner.org/interactives/rockcycle/change.html • Metamorphic rocks are formed when existing igneous or sedimentary comes under extreme heat and or pressure (“squeezing”). • Examples are Marble, and Slate Two groups based on internal structure: foliate- bands or zones of same material Non-foliated- no visible bands or zones Metamorphic • These rocks have literally “Metamorphosed” (changed). • That means they started out as one thing and became something completely different. • They are formed underneath the surface of earth • TSW understand the evidence that shows the Earth has changed over geologic time (including the types of rocks, the rock cycle, minerals, and fossil record). • 4 In addition to score 3, the student can help teach or mentor his/her peers. • 3 TSW understand the evidence that shows the Earth has changed over geologic time (including the types of rocks, the rock cycle, minerals, and fossil record). • 2 TSW understand the evidence that shows the Earth has changed over geologic time (including 2 of the 4 requirements): – – – – Types of rocks The rock cycle Minerals The fossil record *1TSW understand the evidence that shows the Earth has changed over geologic time (including 1 of the 4 requirements):Types of rocksThe rock cycleMinerals, andThe fossil record *0Even with help, the student experiences no success.
