Students learn about using photogrammy (making multiple identical images of a location taken with a camera whose relative position is known to a certain degree of accuracy) to monitor change over time. This set of activities within the following lesson will help students learn about the process of collecting identical images and its importance, and practice collecting images from set locations, first in their own environments and then in the field. With this background, students can participate in photo point data collection during their expedition on Geology Day, and have a better understanding of the importance of this data collection. After the expedition, the class completes the procedure by submitting the images to the cumulative database. In addition, students can use their photos and photos from the database to look for changes in the travertine features, microbes, and other features and ask answerable questions.
