BIOL 1104L – Experimental Report Discussion and Conclusion Assignment Your experiment report is almost done. You have written and received feedback from your GLA and your peers on all the other sections. Now it is time to write your Discussion and Conclusion sections. Save the file as 1104L-DissConc-LastnameFirstinitial 1) A discussion of your findings . The interpretation of your results and what they mean will go in this section. This is where you will discuss how your findings provide supporting evidence to answer the question posed in your introduction. The Introduction section is written from the general to the specific. The Discussion section is written from the specific (your experiment) to the general (background information and other experiments). You must cite at least one peer reviewed source in the discussion . (8 pts) The findings of our experiment strongly support the hypothesis that redworms prefer colder soil for burrowing. Our results indicate that redworms burrowed to greater depths in colder soil compared to room temperature and warm soil conditions. This aligns with the general understanding that cold soil tends to hold higher moisture levels, which is favorable for worms. The preference for colder soil among redworms is verified by the consistent pattern observed across all three trials. Our findings resonate with previous research on the cold tolerance of earthworm species. It is adamant to point out, the review article mentions cold soil temperatures were “detrimental to worm livelihood” (Greiner). While this study and prior studies have highlighted the detrimental effects of subfreezing temperatures, our experiment demonstrates that optimally cold soil temperatures are most conducive to redworm activity. One potential explanation for the observed preference for colder soil could be the moisture content. Cold soil typically retains more moisture compared to warmer soil conditions. This higher moisture content provides a more habitable environment for redworms, facilitating easier burrowing. Conversely, the warmer soil, which likely experienced moisture loss through evaporation during heating, presented less favorable conditions for redworm activity. Overall, our findings contribute to a deeper understanding of the relationship between soil temperature and redworm behavior. 2) What are the conclusions/limitations to your investigation ? Describe your conclusions and include caveats that should be taken into consideration when evaluating your conclusions. What is a specific problem and how might that affect the results, this does not include “human error.” One way to approach this is to think about what you would change if you had to repeat the experiment. In this section you have an opportunity to explain why your results are important and anything you would investigate further. (7 pts) In conclusion, our experiment demonstrates that redworms exhibit a preference for colder soil when burrowing. The consistent pattern of deeper burrowing in colder soil conditions compared to room temperature and warm soil conditions supports our hypothesis. However, it is important to acknowledge the limitations of our study, including the relatively small sample size and the controlled laboratory setting. One limitation of our experiment is the artificial nature of the soil variations, which may not fully capture the complexities of natural soil conditions. Additionally, the short duration of each trial (5 minutes) may not fully represent long-term burrowing behavior of redworms in different soil temperatures. Moving forward, further research with larger sample sizes and longer observation periods would enhance the quality of our findings and provide a more comprehensive understanding of redworm behavior in varying soil temperatures.
