1. . Teachers, please read notes pages before using this presentation.

2.  Sugar  Oranges  Beef  Seafood  Water All of these things can be replaced as they are used. Why is it important to use these resources carefully?

3. Sunshine/solar energy In Florida you can expect about 250 sunny days per year. (There are 365 days in a year.) Homes can be powered by solar energy. How many days per year in Florida are overcast (not sunny)?

4. Wind Energy Offshore wind farm in Florida

5. How do you use water? Plants and animals, including humans, are unable to survive without water. The liquids you drink and many of the foods you eat are mostly water.

6. When we use up all of a non-renewable resource there is no more. No more can be made during our lifetime. Non-renewable resources in Florida include phosphate, oil, limestone, and silicon.

7. Mining is when resources are dug up out of the Earth for people to use. Limestone, silicon, and phosphate are mined in Florida. These are nonrenewable resource. Once these resources are dug all up, they cannot be replenished.

8. Phosphate is mined and made into fertilizer. Most fertilizers say they contain “N” “P” and “K”. These letters are symbols for minerals that plants need. “P” stands for Phosphate – or phosphorous that comes from phosphate. Plants use up the. phosphorus in the soil. and it has to be. replaced for plants to. continue to grow.

13. What is silicon? Silicon is found everywhere in the Universe, but is not found by itself in nature. You will always find silicon bound to other elements, such as oxygen. When silicon is mixed with oxygen it forms silica – which is sand. You're probably sitting near some silicon right now. It's in your computer! When purified, it is a metallic-looking, grayish crystal. While it might be shiny like a metal, it is not a metal.

14. Because silicon is the second most abundant material on Earth, miners have little trouble finding it. Two very common sources would be sand and sandstone. It is usually dug from pits of silica sand or quartz sandstone, with heavy machinery. Very high temperatures are required to produce a reaction where the oxygen is removed, leaving behind silicon. This is known as a reduction process.

17. Limestone is a sedimentary rock composed primarily of calcium carbonate in the form of the mineral calcite. Limestone is a nonrenewable resource.

18. Limestone is used in buildings including the United States Supreme Court building and the Great Pyramids of Egypt. Chances are, the building you are in is made largely of limestone. It is used to make cement and mortar. It is also crushed and used as the base of roads. It is even put in some paints, toothpaste and in some foods.

19. Mining silicon, limestone, and phosphate usually involves removing all of the plants and trees and digging large pits. Sometimes these pits remain and become ponds or small lakes. Sometimes they are filled in with dirt.
