 * The Effects of Different Types of Water on Male Goldfish**

__ Background Information __

=
Natalie and I have both had goldfish. We are wondering if we had used different types of water, the goldfish may have survived longer. Goldfish vary in color, and their healthiness can also be measured by the color of their scales. Goldfish thrive in large tanks or outdoor pools supplied with clean, well-aerated water kept at a temperature of 18° C (65° F). They also do well in slightly murky water. Goldfish eat a variety of foods, including plants, algae, insects, and small crustaceans. As there are over a hundred varieties of goldfish, coloration and physical characteristics vary greatly. I n their natural state, goldfish are olive green in color and subsist on weeds and small invertebrates. =====

__ What We Are Measuring __

Measure color of goldfish (different shades of orange), the pH level of the water, and amount of algae with the different water (tap, well, bottled, and distilled water).

__ Controls __


 * amount of food
 * type of food
 * water temperature
 * size of tanks
 * amount of light per day

__Materials__


 * four fish bowls (school property)
 * four male common goldfish ($5.00)
 * pH paper (provided by the school)
 * a certain amount of water that fits the bowl (

__Hypothesis__

If we put goldfish in tap water, then it will thrive better than in distilled, bottled, and well water.
