Describe and/or explain the role of minerals in the formation of rocks. Department of Mathematics and Science

Minerals and You Every solid material made from nature that’s neither plant or animal--not a living thing is a mineral or made from minerals. Minerals touch our lives in hundreds of ways each day. Life as we know it would not exist without them. What are some minerals that touch your lives? What are minerals? (Discovery) Engage - Display some minerals and say: You wake up in the morning and turn on a light. You wash your face, brush your teeth, and get dressed. You turn on the TV and eat breakfast – a bowl of cereal, a glass of juice, or maybe toast and an egg. You gather your book bag and head out the door—ready to start the day. And almost everything you’ve done so far– and everything you’ll do for the rest of the day—would be impossible without minerals. Click on hyperlink: Minerals and You and or see optional handout: The Importance of Minerals in our Lives for more information. Ask: What are some minerals that touch your lives? Students record responses in their notebook/journal. Ask so what are minerals? That’s right: solid material made from nature that’s neither plant or animal--not a living thing is a mineral or made from minerals. Students write in their or notebook. Let’s look at some mineral resources to see what else we can learn. Go to the next slide. Department of Mathematics and Science

What are the Five Characteristics That Minerals Share? To help you remember try this mnemonic device: N I C S Diner - Naturally Occurring – Not made by humans - Inorganic – Was never alive - Crystalline (crystals) – The atoms form a pattern and repeat themselves in all directions. - Solid Definite Chemical Composition – Example: Salt aka halite has a chemical composition of NaCl throughout Explain: See the Minerals’ Station teacher edition for additional information.

Materials: Two Igneous Rocks (obsidian and pumice or scoria*) Two Sedimentary Rocks (conglomerate and compact limestone or chalk*) Two Metamorphic Rocks (slate and marble*) *Suggested rock types or use photographs from the site Procedures for Exploration: Divide class into small groups of six students. Pass out samples of rocks that include rocks from the 3 types. Students choose a rock to observe, and identify its properties in their journals. Students can place the rocks in a group and have members read their descriptions and see who can identify the designated rock. Students use the dichotomous key placemat sheets to classify their groups rocks into the three types of rocks: sedimentary, igneous, and metamorphic. Students explain their classifying reasoning. Evaluation: Give each group three different rocks from the three different types and have the students identify the group the rocks belong to and give evidence observed as to why.

How do rocks form? Igneous rocks form when magma cools underground or lava from volcanic eruptions cools on Earth’s surface. Sedimentary rocks form when bits of different rocks pile up. Over a long time, the rock bits are buried and squeezed together to form sedimentary rocks. Metamorphic rocks form when igneous or sedimentary rocks are changed by heat and pressure. Explain Department of Mathematics and Science

Erosion Erosion is the movement of sediments from one place to another. Water is the primary agent of erosion, though wind and glacier ice also contribute . Explore and Explain: Students explore using the Gr. 4 AIMS Earth Science Evidence for Erosion centers pp Review weathering and erosion by playing the hyperlink Erosion. Have students define and give examples of erosion in their notebook. Evaluation: Ask: What part do weathering and erosion play in the formation of sedimentary rocks? Weathering and erosion create the small rock particles that, along with organic matter, make up soils. The same small rock particles can be transported by water and find their way to the bottom of lakes and oceans where they form layers. As more and more layers are deposited, the pressure from the weight above and consolidation of the minerals and the particles may cause them to cement together, creating a sedimentary rock.

Part Four: Earth’s Resources
Benchmarks SC.4.E.6.3 Recognize that humans need resources found on Earth and that these are either renewable or nonrenewable. SC.4.E.6.6 Identify resources available in Florida (water, phosphate, oil, limestone, silicon, wind, and solar energy). Department of Mathematics and Science

Earth’s Resources What are some of Earth’s natural resources?
Water Plants Sun Air Wind Minerals rocks Land Soil Oil Coal Animals Engage: Ask the essential question and then click on the hyperlink: natural resources. Have students share responses. Department of Mathematics and Science

What resources are found in Florida ?
Florida has many natural resources: Beaches Pine Forests Oil Cattle Phosphate Citrus Explain: Talking Chips Strategy: Students share work from previous slide’s extension/elaboration and each member in a group name one natural resource in Florida and explain why it is useful and important. Water Limestone Reefs Solar Energy

What are some Renewable Resources?
The sun is a renewable resource. Energy from the sun is never used up. Water is a renewable natural resource. It evaporates from the oceans, precipitates in the form of rain and snow, and flows through rivers and streams back to the oceans. Explain Plants are renewable because plants can grow more plants. Seeds grow into plants that bear flowers. These flowers, when fertilized, produce seeds that grow into new plants. Department of Mathematics and Science

What are Florida’s Renewable Resources?
Oranges Solar Energy Renewable Resources Explain what /Discuss why: Solar energy , orange trees, drinking water, and wind are all renewable resources found in Florida. Florida’s location near the equator and its climate provide an abundance of sunlight all year round which can be harvested as solar energy. The solar panels installed on homes, businesses, and schools will capture the sun’s energy to provide power. Meanwhile, utilizing solar energy can decrease electricity bills and help the environment conserve resources. Florida grows the most oranges in the entire United States. Orange trees are widely cultivated in Central Florida where the conditions of the soil and climate are perfect. Florida oranges are picked from trees that are at least three years old. As an orange tree matures, the number of fruit it produces each year increases. Florida has many sources of water. Most of Florida’s drinking water comes from the Floridan Aquifer. The Floridan Aquifer system is one of the major sources of ground-water not only in Florida but, in the United States. Wind is another one of Florida’s renewable resources that allows moving wind currents to be converted into electrical energy. Although the state of Florida is surrounded by water on three sides, it does not get wind gusts significant enough to power homes and commercial businesses. The government’s “Go Green” Initiatives have challenged scientists to carry out experimental research on wind-generated electricity in parts of Florida. Sources of Water Wind

Why are renewable resources important to us?
Renewable resources can be recreated, although some, like trees, may take more time to renew than we can wait. Nonrenewable resources can be used up. Explain Department of Mathematics and Science

What are Nonrenewable Resources?
They are resources that formed over millions of years. They can not be made again in our children or our grandchildren’s lifetimes. There is a limited supply of these resources and people are using them faster than they can be replaced. What are some examples? fossil fuels: natural gas crude oil coal Minerals: aluminum silver iron Explain Department of Mathematics and Science

What are Florida’s Nonrenewable Resources?
Phosphate Oil Nonrenewable Silicon Limestone Explain/Explore: Oil, phosphate, limestone, and silicon are nonrenewable resources found in Florida that will eventually run out. Have students explore their uses online. Show samples if available. Explain: Break students into groups and have them research the resources 1. What are they used for? 2. Are any of them sources of energy?

Limestone is a nonrenewable Florida Resource
Things that are made from Limestone: building and landscape materials materials used in road construction cement manufacturing *Bonus questions: What type of rock is limestone? Limestone is a sedimentary rock. How do sedimentary rocks form? Explain: (Show a sample of limestone.) Limestone, another one of Florida’s nonrenewable resources, is a sedimentary rock that is naturally occurring in Florida. Pure limestone is made of calcite. Marine organisms are the primary source of the calcite in limestone. Therefore, limestone is mostly found near or within the ocean. Limestone is mainly used in road construction and in building materials. Limestone is also used to manufacture glass and cement.

What are examples of renewable and nonrenewable resources?
Some renewable resources include: sunlight, water, wind, soil, and trees Some nonrenewable resources include: coal, oil, and natural gas Explain Department of Mathematics and Science

What are the differences between renewable and nonrenewable resources?
Nonrenewable resources are resources that cannot be replaced in a short amount of time. Unlike renewable resources, it is possible for humans to use up all of the nonrenewable resources in the world. A renewable resource is a resource that humans are not likely to run out of. Wind is a renewable resource because the wind will always continue to blow on Earth. Trees are a renewable resource because they can be planted and grown in a short amount of time. Department of Mathematics and Science Explain

Saving Resources The world doesn’t have an endless supply of natural resources. We have to make our natural resources last longer. The wise use and protection of natural resources is called conservation. Use cloth shopping bags Ride your bicycle instead of driving Buy recycled products Turn off the water while you brush your teeth Reduce Review and Extend: Click on hyperlink: Saving Resources. Then view Saving Resources and discuss. Recycle aluminum cans Turn off lights when you leave a room Recycle Reuse

Energy Conservation What can we do? We can use resources wisely.
We can reduce, reuse, an recycle. Explain/Evaluate Department of Mathematics and Science

FCAT Review 1. Earth will eventually run out of certain kinds of energy resources. These are called nonrenewable energy resources. Which answer lists ONLY nonrenewable energy resources? solar, geothermal, and hydroelectric natural gas, wind, and water gasoline, solar, and nuclear coal, oil, and natural gas Explain/Evaluate Department of Mathematics and Science Florida Achieves

FCAT Review 2. In Florida, limestone mining produces over 153 million tons of products a year, including concrete, asphalt, and cement. Which of the following best describes how limestone mining should be handled in Florida? It should be restricted, because some people have a toxic reaction to limestone products. It should be restricted, because there is only a limited amount of limestone available. It does not need to be restricted, because new deposits of limestone can be discovered and used. It does not need to be restricted, because limestone can be easily replaced as sediment is compacted. Explain/Evaluate

FCAT Review 3. It is important to develop renewable energy sources like solar, wind, and hydroelectric power. What is the advantage of using these resources, instead of using fossil fuels? They make more energy than fossil fuels. They are cheaper to maintain than fossil fuels. They cannot be depleted or used up, like fossil fuels. They do not depend on weather conditions, like fossil fuels. Explain/Evaluate Department of Mathematics and Science Florida Achieves
