While most of us do not give much thought to water quality, serious aquarists are keenly aware of the importance of maintaining water quality. But while aquarists are careful to maintain ph, nitrates, and ammonia levels, many do not give the same attention to the level of dissolved oxygen (DO). An understanding of the relationship between temperature and DO is the subject of this science project. With the understanding gained from this experiment, you will have insight on how tropical and cold water fish are able to survive in their respective environments. 

Instructions preview
*Prepare three large jars or beakers of with water and label the jars A, B, and C. Check the DO level using the water quality kit. *Record the DO level for each jar on a piece of paper. *Set jar A in a safe place and let it sit for five days at room temperature. *For jar B: Place the aquarium heater and set for 80 degrees Fahrenheit (27 Celcius.). Maintain the temperature for five days. *For jar C: Place the jar in the refrigerator for five days. The temperature within the refrigerator should typically be at 35-38 degrees .....
