1 Department of Mathematics and Science Big Idea 6: Earth Structures Earth’s Resources Grade 4 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). Mary Tweedy, Curriculum Support Specialist Keisha Kidd, Curriculum Support Specialist Dr. Millard Lightburn, Elementary Science Supervisor

2 Water Plants Sun Air Wind Minerals Rocks Land Soil Oil Coal Animals Department of Mathematics and Science natural resourcesnatural resources? What are some of Earth’s natural resources?natural resources

3 What resources are found in Florida ? Florida has many natural resources: Beaches Oil Citrus Water Solar Energy Pine Forests Cattle Phosphate Limestone Reefs

4 Renewable Resources Renewable Resources What are Renewable Resources?Renewable Resources Nature can produce some resources again and again. These are called renewable resources. If we are careful we will not run out of these resources. Trees Food Wind Energy Water Solar Energy

5 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. 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

6 Florida’s Renewable Resources Renewable Resources Oranges Sources of Sources of Water Wind Solar Energy

7 Why are renewable resources important to us? 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. Department of Mathematics and Science

8 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 Copper Rocks: limestone Department of Mathematics and Science

9 Florida’s Nonrenewable Resources Oil Phosphate Limestone Nonrenewable Silicon 1. What are they used for? 2. Are any of them sources of energy?

10 Phosphate is a nonrenewable Florida Resource fertilizer vitamins soft drinks toothpaste Things that are made from Phosphate:

11 Limestone is a nonrenewable Florida Resource 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? Things that are made from Limestone:

12 Silicon is a nonrenewable Florida Resource caulk glass wrist bands many electronic devices Silicon is an element found in 90% of the minerals making up Earth’s crust. It often takes the form of sand. It is used in the production of the following:

13 Value of Renewable Resources Value of Renewable Resources Although fossil fuels are still available today, they take millions of years to form. We use them much faster than nature can make them. Therefore, we need to make more use of renewable energy resources. Solar Energy Wind Energy Water Energy

16 What are some differences between renewable and nonrenewable resources? What are some 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

17 Saving Resources 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. ReuseRecycle Reduce Ride your bicycle instead of driving Turn off the water while you brush your teeth Use cloth shopping bags Turn off lights when you leave a room Buy recycled products Recycle aluminum cans

18 What can we do? We can use resources wisely. We can reduce, reuse, and recycle. Department of Mathematics and Science

19 Assessment 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? A.solar, geothermal, and hydroelectric B.natural gas, wind, and water C.gasoline, solar, and nuclear D.coal, oil, and natural gas Department of Mathematics and Science Florida Achieves

20 Assessment 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? A. It should be restricted, because some people have a toxic reaction to limestone products. B. It should be restricted, because there is only a limited amount of limestone available. C. It does not need to be restricted, because new deposits of limestone can be discovered and used. D. It does not need to be restricted, because limestone can be easily replaced as sediment is compacted.

21 Assessment 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? A.They make more energy than fossil fuels. B.They are cheaper to maintain than fossil fuels. C.They cannot be depleted or used up, like fossil fuels. D.They do not depend on weather conditions, like fossil fuels. Department of Mathematics and Science Florida Achieves
