Part 2: So the greasy spot of the pipette from jar A is bigger than the spot of the pipette from jar B, although jar B contains more oil. I think you couldn't control the suck by the pipette, it's every time a different proportion of oil and water. I tried this experiment several times with different quantities of oil and the results, taken by the greasy spot test, weren't comparable with the amount of oil in the jars. Or do you take liquid with the pipette under the oil film?
Roman Remember oil will float on water - at least in the beginning. My methodology: First I made sure I took the sample from the same part of the beaker each time. I placed the pipette just below the surface - about 1mm and took a small sample - ie oil floats on water. I placed 4 drops from the pipette onto brown paper and waited for it to dry. Any oil in the liquid left a stain on the paper If there was no oil in the sample there will be no stain More in next reply Jason
Part 4: Could it be that this foam is the dispersion-zone where the bacterias "attack" the little oil drops? At the end of the experiment (after 4 weeks) I took the foam of each jar out and put it in a little glazier (picture S5A). After I centrifuged it, there was a white stable, thick shift (picture Ö5A), which looked like protein. Do you think that this shift contains the bacterias, because bacterias are build by protein, and when you shake protein it get fixed?
I am a high school student from Switzerland have done my thesis on oil degradation by bacterias. I tried in my experiment the greasy spot test for meassuring the oil level in each jar, but it didn't worke. So I took another methode. But I'm still wondering how the greasy spot test works and I have no idea how you can be sure that you take the same proportion of oil and water in each jar. It would be nice if you can give me an answer.
To make it more clear, the jars have an equal amount of oil in them at the start, the grease spot test can determine if the oil is decreasing by means of the pipette sucking up more water per oil. Since the oil will be decreasing, less will be available at the top of the water to take from, making the water more likely to be sucked up. Leaving smaller grease spots. It's not a perfect test, but it's still an interesting method.
Thanks for your reply. But for me it's still not clear how this method could work. An example: you have two jars, in jar A is 1.5ml oil and in jar B is 2ml oil, both contains the same quantity of water. If you want to show the difference between the two oil quantities with the greasy spot test, it doesn't work. Perhaps the pipette takes in jar A more oil than in jar B and in jar B more water than in jar A.
Part 3: Another question about the experiment you have done in the video and I have done for my thesis. During the experiment it builds up foam by reason of the aquarium pumps and this foam is under the oil level. What do you think are the ingredients of this foam? (Look at picture 2C 12.6)
Part 2 After I while I suspect some of the oil forms clumps and sinks to the bottom or it adsorbs onto the soil particles. These were questions I posed in the second video for this experiment and which you could test for. Jason
Part 5: I haven't found the second video, is it on your you tube profile? It would be grateful if you could answer me these questions. Regards
Thanks! I answered you by mail, but I'm not sure if it reached you. So I send it here too, unfortunately without pictures.
I sent the pictures in a message on facebook to the talking technology.
Where did you get the nutrients for the bacteria?
