Duckweed Experiment

The hypothesis was rejected in this experiment, based on the results. The results were much different than hypothesized before the experiment. It was hypothesized that the lower concentrations of CLR, Jar E and Jar D, would be healthier and more likely to reproduce than the higher concentrations of CLR, Jar B and C. However, as shown in the actual results, Jar E and D with the lower concentrations of CLR died quicker than Jar B and C. The CLR and water solutions acted as a fertilizer, so the greater the amount of CLR, the longer it stayed healthy or, in the case of Jar C, it even helps the duckweed fronds to reproduce. Ingredients in CLR, when mixed at a certain ratio with water, is actually helpful to the duckweed. There are many experimental
Covering the jars with a thin mesh cover, which would have prevented the spider from falling in but still would allow air to reach the experiment, would have very likely caused different results in Jar C. If the spider had not fallen into the jar, Jar C may have produced the same results as the rest of the jars instead of being an outlier in the experiment. When picking out the duckweed, the selection could have been more accurate or specific, picking duckweed that would have been more similar in size and root length. Some of the duckweed that was selected may have been already reproducing, making there seem as if there is growth in the duckweed when actually the extra frond was just missed when looking over. The experiments of other groups were similar and yet different from this one. The duckweed in many other groups died faster the higher the concentration of whatever substance was being mixed in with the water. In the lower concentration jars or beakers, the duckweed still died, but not as quickly; however in this experiment, the lower the concentration of CLR, the faster the duckweed
