1. Answer both the QUIZ and WARM UP on notebook paper you pick up off table. QUIZ 1.Draw a picture of the water cycle using the proper vocabulary (Precipitation, Collection, Evaporation, Condensation) 2.Predict what would happen in the water cycle if there were no clouds. 3.Are we ever going to run out of water? Why? 4.Does the water cycle happen in the desert? Explain?

2. WARM UP Imagine that you are a producer and are in charge of creating a game show or television show to teach a specific topic. Explain how you are going to get the main topics across to other students learning this topic. Brainstorm what main areas need to be taught. What materials would be needed? How long is episode/game? How are you going to present? How are you going to split class? How are you going to assess the learning ? (PICK ONE TOPIC OFF THE BOARD)

3. CHAPTER 24 WATER QUALITY pg. 31 Essential Question: Explain why the water cycle is important to survival?

5. STUFF ABOUT WATER WATER DISSOLVES MANY THINGS NEARLY “UNIVERSAL SOLVENT” H2O

6. V-SHAPED POLAR MOLECULE WITH PARTIAL NEGATIVE MIDDLE (O-) AND PARTIAL POSITIVE ENDS (H+)

7. HYDROGEN BONDS POSITIVE H ATOMS ATTRACT NEGATIVE O ATOMS FROM OTHER WATER MOLECULES HELPS PLANTS PULL WATER UP STEM AS MOLECULES “HOLD HANDS”

8. DISSOLVING IN WATER POLAR MOLECULES have PARTIAL POSITIVE and PARTIAL NEGATIVE SECTIONS So, they DISSOLVE WELL in WATER NONPOLAR MOLECULES are NEUTRAL ALL OVER So, they WON’T DISSOLVE in WATER like WAX or OIL or BUTTER

9. WAKE UP, EVERYONE !!!

10. CHEMICALS IN OUR WATER CHLORINE to KILL BACTERIA FLUORINE for STRONG TEETH LEAD, IRON, COPPER from PIPES ACID (H+) from SOIL EATS UP PIPES BASE (OH-) from CALCIUM and MAGNESIUM NEEDED for HUMAN HEALTH

12. The WATER CYCLE (HYDROLOGIC CYCLE) EARTH’S TOTAL WATER STAYS THE SAME 97% is SALT WATER 2% is ICE ONLY 1% is FRESHWATER !!!

13. WHERE THE WATER IS - OCEANS -SURFACE WATER -GROUNDWATER in AQUIFERS - ACIDIC with DISSOLVED MINERALS, but DISEASE-FREE -VAPOR in ATMOSPHERE -COMES FROM EVAPORATION AND TRANSPIRATION - CLOUD SEEDING to MAKE MORE RAIN

14. WHAT HAPPENS TO WATER EVAPORATION TRANSPIRATION from PLANTS CONDENSATION in CLOUDS PRECIPITATION RAIN, SNOW, HAIL, and SLEET CAUSE SURFACE RUNOFF

16. WATER QUALITY TEMPERATURE DISSOLVED OXYGEN Fish Die if this is too low BIOLOGICAL OXYGEN DEMAND (BOD) - Measures ORGANIC MATERIAL in water

17. WATER QUALITY Ph - ACIDIC or BASIC Acid Rain TURBIDITY (CLOUDINESS) NITRATE from DECAY and FERTILIZERS PHOSPHATE - DETERGENTS and FERTILIZERS

18. ALGAL BLOOMS Too much Fertilizer (Nitrate or Phosphate) in Surface Runoff causes too much algae to grow ALGAE use up Oxygen FISH die from low oxygen level

19. BYE, Y’ALL DON’T WASTE WATER!!
