As mentioned in my previous post, the topic of my digital story is change in a population influenced by challenges presented by a dynamic environment and changing climate. The star of the story is a long-winged duck named Philbert. Philbert's mate is a short-winged duck named Phylisody. Shortly after having 3 long-winged children Phylisody dies because a drought has made the distance between watering holes on the migration south too great for her little wings to handle. Throughout the story Philbert contemplates what is happening to the land around him and observes the influences these changes have his population of ducks. The story ends with some reflective questions about what might have happened to other populations, it the characteristics of his population had been different and what the future may hold for the ducks that remain.
The main focus of this story was to express the concept of change over time. While creating the story and watching the final product I realized that there are also some underlying concepts that could be reviewed as well. Such as climate change and genetics and probability. As an assessment for students, they could create similar stories where other density-independant or density-dependant factors influenced the change in allelle frequencies.
