Directions+for+Ph

To find the pH of the water, you must put the device in the water from about 10-20 different times. Each time you put it in the water, you should put it in a different area so that the results are more effective. Once you have found about 10-20 readings, record the information and post it. Nothing has to be done inthe classroom for this test.
 * Conducting the pH Test:**

pH is a measure of acidity. The higher the pH, the more acidic the water is. The lower the pH, the more basic the water is.
 * Significance of pH:**

Results between 6.7 and 8.6 support a well balanced fish population. If the results are below 5 or above 9, the water will be difficult for most fish to live in for long periods of time, and plants will experience a slowing of nutrient uptake.
