What about “opinions”?
Where would you go to read about facts?
Where would you go to read about opinions?
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.
Water, Water, Everywhere…
It takes approximately 120 L of water to produce a 1.3L can of juice.
It takes 450 L of water to place a fried egg on your plate.
Explain this….
Comparison
To make the 1.3L juice can takes as much water as:10 showersWashing 10 loads of clothes25 loads of dishesFlushing the toilet 100 times

Objectives
SWBAT draw the steps to the hydrologic cycle
SWBAT define aquifer, ground water, and surface water
SWBAT explain where water comes from
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
Let’s Draw Out the Step.
1. Get some colored pencils.2. Take out a clean piece of paper3. Listen and Draw
3 Facts about the hydrologic water cycle:
City Water
Comes from pipes?Water comes from a reservoir or water
towerWater has been treated and purifiedIf the water originated from a river it is
called SURFACE WATERIf the water has originated from a well
you are using GROUND WATER (well)
Rural Water
Aquifer – (a water-bearing layer of rock, sand or gravel)
Where else can water come from in rural areas?
Review for Test:
Distillation:Can be used to purify drinking waterVery expensive
Gray Water:Water that cannot be used for drinking,
bathing, or cooking
