3. Do Now • What do you consider “facts”? • What about “opinions”? • Where would you go to read about facts? • Where would you go to read about opinions?

4. Objectives • 1. SWBAT pair up with a partner and reread through the fish kill article. • 2. SWBAT distinguish between facts and opinions in a news article. • 3. SWBAT discuss the uses of water.

5. Town in Crisis • Take turns reading about Riverwood’s water crisis • Turn to page 4 of your textbook

6. Think-Pair-Share • Go back through the reading and differentiate between fact and opinion.

7. Town in Crisis • Can we get enough water to supply our needs? • Can we get sufficiently pure water?

9. Water, Water, Everywhere • Juice Production:

10. Water, Water, Everywhere • Egg Production:

11. Comparison • To make the 1.3L juice can takes as much water as: • 10 showers • Washing 10 loads of clothes • 25 loads of dishes • Flushing the toilet 100 times

12. A.4 – Water Supply and Demand • The average U.S. family of four ( 2 adults and 2 children) use an average of 1480 liters (390 gallons) of water daily 12

13. Why is the quantity of water used to make a a can of juice greater than the actual volume of liquid in the can?

14. Do Now - Lab • What are the different ways to purify drinking water?

15. Do Now Lab- 2 • Substances in the oil water separation are separated based on _________. • Substances in the sand filtration are separated based on _________. • Substances in the charcoal separation are separated based on _________.

16. Objectives • SWBAT purify water using charcoal filtration. • SWAT discuss the Tyndall Effect and electrical conductivity test • SWBAT construct a histogram of class data

17. Today’s Agenda • Video • Filter water again, Tyndall Effect, and electrical conductivity test. • Histogram

18. Histogram • Needs a title • Needs labels on X, Y axis • Needs to be accurate

19. Do Now • Explain the different uses of water to create a cup of coffee in the morning.

20. Objectives • SWBAT identify water use as either direct or indirect. • SWBAT review answers to last night’s homework. • SWBAT analyze water use in the US.

21. Direct vs. Indirect Water Uses • Direct Water Use • Water that can be directly measured • Indirect Water Use • Water that you don’t usually consider using

22. Classify the following example as direct and indirect uses of water • Making a cake…

26. Questions # 1-3 on pg. 17

27. A.6 Where is the world’s water? What forms of water are depicted? How large is this glacier compared to the people? Even though much water is stored here is it accessible? Could the U.S. obtain drinking water from here?

28. States of Water • Gaseous State: • Water Vapor • Liquid State: • Water, lakes, rivers, oceans, clouds, and rain • Solid State: • Ice

29. Do Now • List an example of each state of water. • Explain where your would find each example.

30. Objectives • SWBAT draw the steps to the hydrologic cycle • SWBAT define aquifer, ground water, and surface water • SWBAT explain where water comes from

31. Where is the world’s largest supply of fresh water? • Most of the Earth’s total water is from the ocean (about 97%) • The remaining 3% is fresh water and it is stored in glaciers

32. Distribution of World’s Water Supply

33. Hydrologic Water Cycle http://polaris.umuc.edu/cvu/envm/hydro/hydro.html

34. Let’s Draw Out the Step. • 1. Get some colored pencils. • 2. Take out a clean piece of paper • 3. Listen and Draw  • 3 Facts about the hydrologic water cycle:

35. Think-Pair-Share

36. City Water Comes from pipes? Water comes from a reservoir or water tower Water has been treated and purified If the water originated from a river it is called SURFACE WATER If the water has originated from a well you are using GROUND WATER (well)

37. Rural Water Aquifer – (a water-bearing layer of rock, sand or gravel) Where else can water come from in rural areas?

38. Let’s review the answers to questions: 8-10 on pg. 23

39. Review for Test: • Distillation: • Can be used to purify drinking water • Very expensive • Gray Water: • Water that cannot be used for drinking, bathing, or cooking

40. Do Now • How do you think you could cut down on water consumption at home? • List at least 3 ways.

41. Objectives • SWBAT review answers to the foul water lab. • SWBAT analyze previously collected data about household water usage and compare it class and national averages

42. Do Now • Compare and contrast an aquifer and ground water.

43. Objectives • SWBAT brainstorm how they can use simple objects to purify water • SWBAT multiple choice questions and short answer to help review for their test.

44. Think-Pair-Share • To help review for the test turn to page 24 and answer question 18~!
