Safety

CAUTION: Be sure to warn your students about the fact that the LaMott Water Testing Kit contains dangerous chemicals and that they should only be used as prescribed by the directions.

Information

• The lab uses the LaMott Water Testing Kit for dissolved oxygen. Other kits may be used to determine the amount of dissolved oxygen in a water sample.
• Thermometer or a temperature probe may be used to determine the temperature of the water sample. This parameter really should not change.
• Universal pH paper or a pH probe may be used to determine the pH of the water sample. This parameter may depend on the make-up of the pond water.
