15. Pass the Salt     10 Points
Estuaries are bodies of salt water that are fed by freswater sources.
Fresh water is mixed with saltwater. 
The salinity can vary with distance from the freshwater source. 
Estuaries form the boundary betwen marine and freshwater habitats. 
They are breeding grounds for thousands of aquatic animals and plants. 
Elodea is a common freshwater plant which is found in estuaries where freshwater is abundant.

Problem

Materials
four 2-liter plastic bottles
three 1-liter plastic bottles
test tubes or baby food jars
test tube rack
pond water
salt
gram scales
Elodea plants
1-liter measuring cup
masking tape

Procedure
1. Obtain pond water in four 2-liter bottles.
2. Prepare salt solutions in each 2-liter bottle.

3. Label each test tube or jar.
4. Fill each test tube or jar with a different concentration of water.
5. Put a short piece of Elodea in each test tube or jar.
