Transcript

  • 1. 3/14/12 A/B DayLEQ: How do we use water as a naturalresource and how can we protect it?1. What is a food web?2. What is a an example of how an aquatic and aterrestrial food web can be interconnected?3. What is an example of an organism you wouldpredict to find in the FIRST trophic level?4. What is an example of a primary consumer?5. Copy and complete: The higher up the foodchain, the [higher/lower] amount of energy istransferred.
  • 2. Let’s Review!
  • 3. Today’s LEQ: How do we use water as a natural resource and how can we protect it?By the end of today, you should be able to…1. Describe how we use the hydrosphere for food, water, and air2. Distinguish between point- and non-point- source pollutants3. Describe the pro’s and con’s of using chemicals in our hydrosphere
  • 4. Focus Vocabulary:136. Natural Resource137. Desalination138. Dissolved Oxygen139. Point-source pollution140. Non-Point source pollution
  • 5. Activating StrategyYou are going to be living on a deserted island for therest of your life—you can’t escape from the island (nomatter what you bring!) and you can only take 5things with you. What would you bring?
  • 6. Ms. Lorant’s Deserted Island List:1. Water purifier2. My bed3. A waterproof laptop with internet access4. Lifetime supply of Cookout cheeseburgers5. War and Peace (a 2,000 page book)
  • 7. Three things every livingthing CAN’T live without:
  • 8. The hydrosphere gives us ALL THREE!!!
  • 9. How do we use water as a natural resource?
  • 10. Think-Pair-Share:What is a natural resource?
  • 11. How do we use water as a natural resource?Air: Water: Food:
  • 12. How do fish breathe underwater?
  • 13. BrainPop: Gills
  • 14. AIR:-There is dissolved oxygen in water!
  • 15. Where does theoxygen in water COME from?
  • 16. BrainPop: Algae
  • 17. Chemical Reaction: PhotosynthesisWhat are the reactants?What are the products?CO₂ + H₂O  C₆H₁₂O₆ + O₂ Water Oxygen!Carbon GlucoseDioxide (plant food)
  • 18. AIR:-There is dissolved oxygen in water!-Algae photosynthesis puts oxygen intothe water and the atmosphere PhotosynthesisSunlight + Carbon Dioxide  Energy +Oxygen!!!!
  • 19. Hot Q:What do you think would happen ifthe algae in the hydrosphere wentextinct? NO MORE OXYGEN!!
  • 20. WATER:-97% of our water is salty-Desalination: process ofseparating salt from oceanwater
  • 21. Discovery Education: Desalination What are some of the pro’s of desalination? What are some of the con’s of desalination?
  • 22. FOOD:-75 million TONS of ocean fishare eaten by humans each year-we eatfish, shrimp, oysters, crabs, mussels, lobsters, seaweed, and kelp
  • 23. Seaweed in WHAT?carrageenan
  • 24. How Humans Affect Water:1. What do we call something that cancontaminate or infect our water?2. What is the difference between a point-source pollutant and a non-point-sourcepollutant?3. How can pesticides and fertilizers polluteour water supply?4. What are some of the pro’s and con’s of usingchemicals that can infect our water?5. What can you do to help keep our waterclean?
  • 25. Animal Waste in our Water Supply:• http://scorecard.goodguide.com/env- releases/aw/nc-hog-campaign.tcl
  • 26. Discovery EducationFrontline: Poisoned Water
  • 27. Draw this in your notes:Point-Source Non-Point-SourcePollutant Pollutant
  • 28. SORT THESE!-pollutant that is often hard to identifywhere it comes from-pollutant that comes from a single point-pollutant that is easy to identify thesource-pollutant that can come from manydifferent sources-ex. Acid Rain-ex. An oil tanker spills oil into the ocean
  • 29. Point-Source Pollutant:• Pollutant that comes from a single point• Pollutant that is easy to identify the source• Ex: an oil tanker spills oil into the ocean
  • 30. Non-Point-Source Pollutant:• Pollutant that is often hard to identify where it comes from• Pollutant that can come from many different sources• Ex: Acid Rain chewing and contracting of stomach muscles
  • 31. BOTH:• Are caused by humans• Can contaminate our water supply
  • 32. Point-Source Non-Point-Source ?
  • 33. Point or Non-Point?Fertilizer from miles and miles of farmland runs off and pollutes a river
  • 34. Point or Non-Point?A Nike shoe factory buries a crate of toxic waste.
  • 35. Point or Non-Point?Hundreds of 18-Wheelers release several tons of particulate matter into the air
  • 36. Point or Non-Point?A factory smokestack pours several tons of greenhouse gases into the air
  • 37. Point or Non-Point?A person throws garbage onto the side of the road
  • 38. Point or Non-Point?Acid rain infects a city’s water supply
  • 39. Gallery Walk:This is a ________________ because _________.
  • 40. • Damaged pipe dumps wastewater into a river• Raw sewage is accidentally released into a lake• Chemicals from a paper company are dumped into tributary• Sewage from a home is poured directly into a water system• Chemicals from fertilizers in agricultural fields run off into the hydrosphere• Dirty water from city streets is washed into the ocean• Fish are contaminated with mercury from factories that burn coal• Acid rain
  • 41. Summarizer:1. Describe how we use water as a natural resource for food, air, and water.2. How does human activity cause pollution in our hydrosphere?3. Would you rather be in charge of fixing a point- source pollution problem or a non-point solution problem?4. Explain your answer to #4!5. What are some of the pro’s and con’s of having agriculture in North Carolina?
  • 42. Identifying Point- and Non-Point-Source Draw this in your notes:Point-Source Non-Point-Source
