1. RESOURCES Non-renewable vs. Renewable Human uses/consumption/pollution Earths Natural Cycles

2. HMMMM.... What do you think nonrenewable resources are? Break it down... Nonrenewable? Resource?

3. NONRENEWABLE RESOURCES A nonrenewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption.

4. NUCLEAR ENERGY Nuclear fission uses uranium to create energy. Nuclear energy is a nonrenewable resource because once the uranium is used, it is gone!

5. COAL, PETROLEUM, AND GAS Coal, petroleum, and natural gas are considered nonrenewable because they can not be replenished in a short period of time. These are called fossil fuels.

6. HOW IS COAL MADE ???

7. HOW ARE OIL AND GAS MADE ???

8. WHAT WAS THE DIFFERENCE BETWEEN COAL AND OIL/GAS?

9. HMMMM.... If nonrenewable resources are resources that cannot be re-made at a scale comparable to its consumption, what are renewable resources?

10. RENEWABLE RESOURCES Renewable resources are natural resources that can be replenished in a short period of time. ● Solar ● Geothermal ● Wind ● Biomass ● Water

11. SOLAR Energy from the sun. Why is energy from the sun renewable?

12. GEOTHERMAL Energy from Earth’s heat. Why is energy from the heat of the Earth renewable?

13. WIND Energy from the wind. Why is energy from the wind renewable?

14. BIOMASS Energy from burning organic or living matter. Why is energy from biomass renewable?

15. WATER or HYDROELECTRIC Energy from the flow of water. Why is energy of flowing water renewable?

16. SUMMARY What are the differences between nonrenewable and renewable resources?

17. 8 th Grade Science 10/16/2014 Essential Question – How have humans impacted the Earth’s natural processes? Objectives – I can… –explain how the continued use of limited resources could effect the earth's geological process. Bell Ringer – Take out your bell ringer paper. Copy and answer the following question: Why is the conservation of non – renewable natural resources important?

18. Agenda For Today: 1.Go over writing assignment. 2.Watch and discuss video 3.Notes on human impact on the environment. 4.Begin critical thinking assignment.

19. Writing Activity: What are the differences between nonrenewable and renewable resources?

20. Video Captain Planet A Hero for Earth 1.What did the spirit of Earth see? 2.Who did this to planet Earth? 3.Who did she call to fix the problems? 4.Why do you think she called kids to save the planet? Why not adults? 5.Why do you think she called kids from all over the planet?

21. Common uses of Earth’s Resources Common uses of natural resources are everywhere. It is nearly impossible to cease consuming natural or geologic resources altogether. Here are just a few examples of things you commonly use, but probably don't think about: –A pencil uses zinc and copper (to make the brass), petroleum for the eraser, iron (in the machinery to make the pencil), pigments, clay and graphite. The only renewable resource in your pencil is the wood –Your jeans, although they may be almost all cotton, are usually blended with petroleum-based synthetic fibers to cut down on shrinking. The zipper on those same jeans is made out of copper and zinc. The dye in all your fabrics come from petroleum.

22. Humans and Conservation Because of the severe impact that we impose on the land, air, and water, conservation has become increasingly important. Conservation is using natural resources wisely and not contributing to pollution of the land, air or water. Human activities can benefit the environment and help preserve resources. Conservation can include: – small-scale cleanup projects along roadways – building fences to prevent dune erosion to large-scale beach cleanup. –Planting trees is another way to support conservation as trees are too often removed without being replanted.

23. Humans and Conservation cont. The phrase “Reduce, Reuse, and Recycle” has been a catch phrase of the late 20th and early 21st centuries. Reduce: Don’t use a resource if there is an alternative (walking vs. driving) Reuse: Use a resource again without changing it or reprocessing it: Use glassware as opposed to paper plates and Styrofoam Recycle: Reprocess a resource so that the materials can be used in another item. People can recycle just about anything from cardboard to old shoes! Protect: Prevent the loss of a resource (wildlife) by managing its environment. Rapid deforestation can wipeout both animals and plant life. By controlling the environment, we can control the resources.

24. Humans and Pollution Pollution is anything that harms or degrades the natural environment.

25. Humans and Water Pollution Water: The ocean supplies billions of living organisms and animals with nourishment and is a sensitive ecosystem that can be polluted very easily.

26. Humans and Land Pollution Land: Landfills occur all over the U.S., and contaminants in the landfill can leach into the nearby soils and groundwater, contaminating the ground we walk on and the water we drink.

27. Humans and Air Pollution Atmosphere: We pollute the atmosphere mainly by burning fossil fuels. This produces greater than 10 times the amount of greenhouse gases that make it to the atmosphere through natural processes.

28. Think about it… Why do you think you have to learn about how humans are impacting the Earth? What can you do to have a positive impact on the environment? Describe your possible solution.
