Sketching is a powerful tool to capture observations about the landscape and preserve a picture of a field site at a particular time. At the same time, our perspectives, be they disciplinary, personal, or literally where we are standing when making observations, color the way that we see things. This lesson asks students to make sketches of a field site over progressively shorter windows of time (10 minutes, 4 minutes, 1 minute) before and after conducting geomorphic data collection at the site. The expected outcome is that students will see and focus on different aspects of the landscape after collecting data, helping them to see the way that disciplinary learning informs their perspective. The activity also encourages them to consider their sketches as data rather than focusing on artistic ability. Students will also build skills in hypothesis generation and field data collection, as they collect basic geomorphic data that can be used in an assessment for this individual lesson or in subsequent lessons.
