Title:
The effects of tap water and mineral water on the germination and growth of herbs.
Introduction:
How will tap water and mineral water affect the germination and the growth of herbs? My hypothesis is that the herbs will best germinate and grow in mineral water. Mineral water may have fewer contaminants that can hurt the germination of the seeds and perhaps this absence will help the growth of the plants. Mineral water is water from an underground source that contains at least 250 parts per million total dissolved solids (Bullers). I also think that tap water will have a detrimental effect on both the germination and the growth of the plants. In this experiment, I will use Evian bottled water and tap water to test the growth and germination and growth of basil, parsley, and chives over a four-week period.
Methods and Materials:
The materials used for conducting the experiment included the following: six terra cotta pots, 6 soil pellets, metric ruler, chives seeds, parsley seeds, basil seeds, tap water and Evian mineral water.

Then, I put a soil pellet in the bottom of each pot. The soil pellets use 2 tablespoons of water to expand. I used bottled and tap water to keep the experiment as precise as possible. Next, I put the seeds into each terra cotta pot about 1/4" into the soil. Then I began my experiment by watering the labeled plants with one teaspoon per plant with the appropriate water sample. I then placed the plants in a windowsill for sunlight. I water each of the plant with the fixed amounts of water every day for four weeks. At the end of...
