Introduction
“A Pond is commonly described by limnologists as a quiet body of water so shallow that rooted plants grow completely across it. Its water temperature is fairly uniform from the top to bottom and tends to change with air temperature. There is little wave action; and the bottom is usually covered with mud. Typically, plants grow all along the shore. The amount of dissolved oxygen may vary greatly in a 24 hour period.” (Pond Life 2001) There are several environmental factors that are essential in maintaining stable pond life. If any of the factors drastically change the results may increase or decrease the life within the pond. If there is more algae sediment in a controlled environment then more protozoa’s will be observed. If the pond water is in a controlled environment, then the pond life should remain stable.
Materials
Glass jar with metal lid
Shovel
Large scooping spoon
Large long handled Dbl headed ax
Hammer-nail
Compound Microscope
Plastic disposable pipette
Water Quality test strips
Microscopic slides w/cover slips
Thermometer
24 hour lit area
Methods
The area that the Pond water was collected is just off of M-20, Mount Pleasant, Michigan. Date & Time collected: February 26, 2010. At this site there is a mid-sized pond several decades old. The weather was a blustery 10*. The spot chosen for collection was a quarter of the way into the pond on the NW side. A shovel was used to remove 2’ of snow; a long handled ax was then used to slice through 7 ½ of solid ice before successfully reaching unfrozen water. The specimen container was then dipped into the water, and filled half way, then a large spoon was used to dig into the sediment and it was carefully placed into the jar,
