  1. AQUATICS UNIT 2 WATER PROPERTIES NOTES

  2. NITROGEN • * #1 FERTILIZER • * _____ATE=SOLID WASTE • * ___ITE=LIQUID WASTE • * PLANTS MUST HAVE-MAIN FOOD-MAKES THEM GREEN • * LOTS IN THE AIR, BUT ANIMALS CAN’T CONVERT-ONLY LEGUMES=NITROGEN FIXATION • * TOO MUCH IS TOXIC=“BURN LAWN”

  3. PHOSPHORUS • #2 OF FERTILIZER • HELPS PLANTS BLOOM AND PRODUCE FLOWERS AND FRUIT/VEGGIES • TOO MUCH CAUSES HIGH ALGAE GROWTH WHICH STEALS O2 LEVELS FROM WATER

  4. SEWAGE • 3 TYPES • ANIMAL WASTE • DEBRIS • CHEMICAL • SPILLS ARE OBVIOUSLY TOXIC • RUNOFF IS A FORM OF SPILL

  5. TEMPERATURE • IS A CATALYST OF CHANGE FOR ALL WATER QUALITY VARIABLES • MOST IMPORTANTLY D.O. + pH

  6. BRACKISH • * MIXTURE OF FRESH AND SALT WATER • * WHERE RIVERS MEET THE OCEAN=ESTUARIES • * LARGEST NURSERIES ON EARTH

  7. CAPILLARY ACTION • * WATER PROPERTY THAT DEFIES GRAVITY • * STRAW IN WATER • * BECAUSE OF POLARITY-CAN “CLIMB-LIKE CHAINS • * HOW PLANTS GET WATER FROM ROOTS TO THEIR TOP

  8. BUFFER • WHAT IS ADDED TO A SOLUTION TO BRING IT TO BALANCED • FIND OUT WHAT TO USE BY MEASURING pH THE ACTION OF MEASURING THE pH IS TITRATION

  9. watershed • Land formations that cause water to gather • Grapevine is a watershed to Bear Creek which directly feeds into the Trinity River • Trinity River=longest interior river in Texas, covers over 400 miles

  10. Specific conductance • * HOW MUCH ELECTRICITY WATER CAN CONDUCT • * MORE DENSE=INCREASED CONDUCTIVITY • * LIKE STEPPING STONES ACROSS A RIVER

  11. WATER DENSITY • D=M/V • MOST ABUNDANT LIQUID ON EARTH SO MOST LIQUID DENSITIES ARE COMPARED TO WATER • MEASURES HOW MUCH “STUFF” IS IN THE WATER

  12. TITRATION • ACTION • TESTING TO FIND LEVEL OF ACID OR BASE IN A LIQUID • Ph IS THE TOOL • BUFFER IS THE ADDITIVE TO BALANCE

  13. SURFACE TENSION • BECAUSE OF POLARITY, WATER SITS LIKE A NET • SMALL ENOUGH OBJECTS CAN “STAND” ON THE NET

  14. RUNOFF • NOT NATURAL EXCEPT ON CLAY=FLASH FLOODS • URBAN CAUSE=CONCRETE • PROBLEM=COLLECTS SEWAGE AND TAKES IT TO WATER SOURCE

  15. DISSOLVED OXYGEN • THE AMOUNT OF OXYGEN AVAILABLE IN THE WATER • MOST COMES FROM TURBIDITY AND PHOTOSYNTHESIS

  16. MICKEY MOUSE • BECAUSE OF ION CHARGES THE WATER MOLECULE LOOKS LIKE MICKEY MOUSE

  17. PESTICIDES • * CHEMICAL AND NATURAL METHODS TO KILL ANYTHING THAT BUGS YOU • * PROBLEM=RUNOFF AND LEACHING

  18. TURBIDITY • THE TURNING OVER OF WATER TO BREAK THE MOLECULES TO CREATE DISSOLVED OXYGEN

  19. Ph • MEASURES THE AMOUNT OF OH- (BASE) OR H+ (ACID) IN A SOLUTION • LIVING ORGANISMS WANT TO BE AT 7 • CAN ONLY SUSTAIN SMALL AMOUNTS OF CHANGE OFF OF 7 • USUALLY NO FURTHER THAN 6 OR 8

  20. SEDIMENT • A CONCERN WHEN IT IS SUSPENDED • HARD FOR ORGANISMS TO OBTAIN O2

  21. MICROORGANISMS • TOO SMALL TO SEE WITHOUT ASSISTANCE • CATEGORIES • VIRUS-NONLIVING, USUALLY PATHOGENIC • BACTERIA-ITS OWN KINGDOM, BENEFICIAL=DECOMPOSERS, PATHOGENIC IF IN EXCESS • PROTIST-OWN KINGDOM-SINGLE CELL, PLANTS=ALGAE, ANIMAL
