Bean+Lab


 * Bean Lab**

In this lab, we worked on observing and categorizing beans. This experiment used both qualitative data as we wrote down observations about the beans (e.g. color, shape) and quantitative findings about the beans (e.g. number in group, average length, and average mass). We took pictures of each group and named the different groups. Also, using the quantitative results of the average length and average mass, we created a scatter plot graph for average length vs. average mass.

In this lab, I was able to make the qualitative observations with relative ease, as the beans were right in front of me and I just chose to record the relative size, color, and shape of the 'species' of bean. The qualitative data on the other hand was harder because there were so many beans, therefore, we were instructed for the average length, line the beans up, measure the length, and divide by the amount of beans. Likewise for the average weight, we weighed the beans in the same group together, then divided by how many there were. This made it easier but also less accurate. In this lab, I learned how to categorize objects into 'sub-species' by observing them and collecting data concerning the length and mass. I also practiced my graphing skills by graphing the average length vs. average mass in a scatter plot. However, if I were to repeat this experiment with more time, I would like to ensure the accuracy of my data by measuring and weighing every single bean in each group, recording that information, then averaging the collected data to make my findings more accurate. This experiment was a great way to introduce the idea and practice of categorizing, a much needed skill in Biology, and the ways in which it is done (qualitative vs. quantitative data).
