Description

|---|---|---|---|
| 1 | <p>During a single lab period, students simulate colonization and drift in artificial communities to understand how these processes affect distributions of biodiversity in small versus large communities with varying degrees of isolation. Plastic bins represent islands, and are situated to represent different degrees of isolation. Ziploc bags of candy represent individuals in the communities and different candies inside the bags represent the genetic composition of the individuals. Students simulate colonization and drift in communities by tossing, replicating, and removing individuals from their communities. Students record which individuals and candies are removed from and added to their communities over time, graph their data, and discuss results.</p> | 1 | <p>This adaptation of this module asks students to enter their own data in a provided Google Sheet, download the class data, and plot and analyze it using Excel. The Google Sheet provided here works for community composition data recorded in every round of the activity, which is a time intensive way for students to collect data. Future adaptations could modify the Google Sheet to allow for students to enter just data collected for changes on their island: reproduction, migration, or mortality. An Excel template for analyzing the class data is also included.</p> |

| 3 | <p>To make the in-class activity smoother, two changes were made. A student handout for stepping through each part of each round of the activity is included. To improve the randomness of migration patterns, printable instructions for incorporating a dice roll are included. These instructions can be distributed to each bin for student reference.</p> | ||

| 5 | <p>Finally, teaching notes on this implementation are included.</p> | ||
