Pond Water TITLE: By: Jacob O’Connor November 21, 2011 Jennifer Mertz BIO 101 SEC 3A Mid Michigan Community College HYPOTHESIS: If the pond water is not treated and is good quality water then there will be new organisms and plant life in the pond water ABSTRACT: The objective of this study was to observe and understand what occurs in a sample of pond water over the course of six weeks. Over the six weeks there were qualitative and quantitative data found and recorded.
The qualitative data recorded entailed: Water color and smell as well as suspended solids ranging from clear, opaque, and turbid. The quantitative data that was recorded regarded: Temperature, pH, Alkalinity, Hardness, Chlorine, as well as, Nitrate, and Nitrite. There were also two views of microscope observations. This report will explain and go into detail regarding the results of the observation of the pond water. INTRODUCTION: MATERIALS: 1. Water 9. Slide covers 2. Soil/Grass 10.
Plant grow lights 3. Jar 11. Lab Manuel Books 4. Microscope 12. Nail 5.
Thermometer 13. Hammer 6. Water quality test strips 14. Tape 7. Pipette 15. Nitrate/Nitrite strips 8. Slides 16. Lab Manual METHODS: Located in a 16 oz clear glass or plastic jar. Took the lid of the jar off and punctured holes in it metal lids are usually est, because you can use a hammer and a larger nail to puncture holes; where as a plastic lid tends to crack with a hammer and nail. Found a pond that contained water year round. Filled the jar 3/4 full with pond water. Added a 1/2 inch of sediment from the bottom of the pond.
Also, added a small amount of dead grass or leaves to the jar. Prevented spillage while traveling, by placing a paper towel or plastic wrap between the top of the jar and then gently screwed the lid on over the plastic.
Once in the lab, label the pond water using a stick on label with your name, instructor’s name, class section, and the date of when the pond water was collected which was on 10/05/11. Then each week for 6 weeks this data was recorded, the water color, the smell, suspended solids such as clear opaque, and turbid, the temperature was recorded each week using Celsius, the pH level, total alkalinity, total hardness, total chlorine, and free chlorine.
