Over the course of six weeks, we saw a lot of changes in the Thalli. We noticed that the growth of thalli in the nitrogen and phosphorus solution was significantly higher than when we started. We also noticed the growth of thalli in the creek water solution was relatively …show more content…
Then we placed five Thalli in each well so that there would be a controlled start to the experiment. We then placed them in growth chambers every week so that they could have the proper conditions to grow. Every week we counted that thalli in each well, recorded the data, and refilled the wells with the solutions corresponding to the wells being filled. We did this for six weeks with an exception of one week because we didn’t have class. We also made sure that the labels on the tape were consistent with each other in case that would affect the amount of light each well got in the growth chamber. When calculating our results we averaged the difference of the duckweed in each of the wells for the water with the NP solution set from day one to the last day we checked them, and averaged the difference of the creek water from day one to the last day of the experiment as
