1) Our project topic is “Are there magnetic bacteria in Lake Ansley Moore?”. The purpose of this experiment is to determine if there are actually magnetic bacteria, magnetotactic bacteria (MTB), in Lake Ansley Moore. These bacteria like areas with low oxygen levels, “Thus magnetotaxis helps to guide cells in each hemisphere downward to less oxygenated regions of aquatic habitats. Once cells have reached their preferred microhabitat they would presumably stop swimming and adhere to sediment particles until conditions changed.” (Bazylinski). Magnetotaxis refers to the behavior of bacteria as they move along magnetic field lines. MTB are microorganisms that belong to a heterogeneous group of gram-negative bacteria and are a diverse group of aquatic …show more content…
About ½ gallon to a gallon. Do the same with the sediment/mud in 2 other buckets.
Step 2: In one of the bowls, cut the newspaper into ½” thick strips, then cut those into ¼” long; making a rectangle ½” x ¼”
Step 3: In the second bowl add the egg yolk
Step 4: Slowly add in the water you collected into the sediment/mud buckets until you get a creamy texture. Make sure there are no leaves or sticks in the mixture.
Step 5: In the large mixing bowl, add 2 cups of the mud mixture and a third of the egg yolk. Then move the mixture over into the 24 oz mason jar, taking up about 85% of the jar. Do this for the two different locations and two different food sources; 4 jars.
Make sure to mark each jar with the proper location and food source
Step 6: Let the jars sit for half an hour. Carefully add more water/remove some, as needed. Leave at least ¼” of space on top. Put the lids on your jars.
Step 7: Place a magnet on the outside of each of the jars, use a rubber band/tape to secure it.
Step 8: Let your jars sit for 6 weeks and observe the changes, color/layering, every
