Nightcrawlers Experiment
To sum things up, our hypothesis of the nightcrawlers would be affected by greywater, but those exposed to Ecos would exhibit less off an effect was not supported by the data. On figure one, the trend for all the detergents and control, was about the same throughout the weeks. Excluding the detergent Gain for week five and six, where the trend was slightly less compared to the control and the other detergents which were about the same.
Unfortunately, we did not have any data for week four due to the Astros parade, and during the fifth week of data collecting, two nightcrawlers went missing during the experiment in one of the containers, so the results for the Gain at 0.06% were inaccurate and the six week mass count as shown in figure one, …show more content…
What did not really help the experiment was that the percent change in mass for the control varied between zero to negative fifteen. There was one outlier on the graph, and that was the Gain (0.06%). This is from the drastic decrease in mass for the nightcrawlers here. This is due to the missing worms stated before, causing the decrease in the total mass.
The calculated ratio that was used, was the amount of detergent in milliliters with the output amount of greywater for an efficient washing machine. The different concentration of detergents that was used was to imitate different loads of laundry. On the back of the liquid detergent bottle, we calculated the ratio of each type of load and reduced it to microliters of detergents to 100 mL of tap water in order to run the experiment. If we were able to run this experiment again, we would water the experiments every two day or every three days. Also taking the mass of the nightcrawlers before the soil is mixed with the solution, can give a more precise change to the nightcrawler’s activity and mass change, as well as more data points. Also doing multiple (~three) replicates at the same time, can give us an idea to see if the same trend is the same across each treatment. Another idea is doing the same experiment but with regular powder detergent to see a change as well, since many consumers do not use
