JoinScience Sampler: Taking steps to understand geologic time
Getting students to understand the concept of geologic time is challenging because it is difficult to imagine the vast time frame of Earth’s history. Therefore, this article describes an inquiry-based activity that uses an experiential model to help students understand geologic time. It allows students to visualize vast expanses of time on a personal scale. By the time the lesson ends, students are motivated to research information for their time line.
