Earth Science Week 20

Hydrology

Fresh Water


Monday Warm Up (113)

  • Draw and label a diagram of the water cycle (small).


Review

  • Water cycle

  • Divide

  • Water shed

  • River systems

  • Tributaries


Chattahoochee River Watershed Power Point

  • Where does the river start?

  • Where does it end?

  • What are the tributaries? Can you find a map?

  • Sources of pollution

  • Protecting the river

  • Recreation on the river

  • Water from the river

  • Other uses for the river

Tuesday Warmup (113)

  • A family lives 50 miles from the nearest stream or lake and gets water from a well. Where does the water in the well come from?


Groundwater

Zone of aeration

Zone of saturation

Water table

Aquifer

Porosity

Permeability

Impermeable

friction

Recharge zones

Spring

Artesian spring

Well

Stalactites

Stalagmites

Dripstone column

sinkhole

Ground water Cornell Notes p. 320-325 (IAN 9)


Wednesday Warmup (113)

  • If the recharge zone for south Georgia aquifer is in Columbus, what will happen if that city grows larger?


Building Aquifers

  • Include deep well and shallow well

  • Use permeable and impermeable materials

  • Demonstrate how to discharge from well

  • Demonstrate affect of rain

  • Demonstrate affect of pollution (food coloring) – Can you protect your well?


Thursday Warmup (113)

  • Explain how water in a well can be polluted by chemicals dumped away from the well.


Pollution

Point source pollution

Non-point source pollution

Water Quality

Dissolved Oxygen

Nitrates

Alkalinity

Sewage Treatment plants

Primary treatment

Secondary treatment

Septic tanks

Water use: industry, agriculture

How to conserve water at home

Using Water Wisely p. 324-331 Cornell Notes (IAN 11)


Friday Warm up (113)

  • What would happen if Lake Lanier became polluted? Would that worry you?

  • Hint: Cobb County and most of metro Atlanta get water from Lake Lanier.


Clean it Up!

  • Your team has been assigned to the water treatment facility.

  • Your task is to use the items given and devise a method to remove the pollutants from the water.

  • You can try several methods or you might try using the same method more than once.


IN IAN

  • Describe your method and why you think it will work.

  • See me to approve the method before you try it.

  • Ticket out the door: What was the best method? Why did it work?
