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 O 2 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 O 2

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
