The finalized lesson plan is a 90- to 120-min educational module, downloadable at, along with supporting spreadsheets and a video demonstration of the material. The teaching methods, developed iteratively during 2 years of Lab Days, were incorporated in a Geochronology Lesson Plan and Material Kit. To further develop the module, a teacher workshop was conducted to identify educators’ needs and perspectives. We also developed and tested a “Lab Day on the road,” where scientists traveled to a local high school to introduce hands-on exercises and lead discussions related to geochronology. These revealed that students greatly appreciated the hands-on exercises and that the exercises resulted in a significant increase in knowledge. Student performance and learning impact were assessed using pre-tests (1 week before the event) and two post-tests (1 week after the event and 4 months after the event). During several Lab Day tutorials, students from local high schools attended a day of workshops, participating in hands-on exercises and a discussion of geochronology in earth science research. The exercises focus on the uranium-lead (U-Pb) dating method using the mineral zircon with applications to solving geological problems. As part of the EARTHTIME outreach initiative, we have developed an educational module that teaches students about the basics of geochronology and how geologic time is measured. ![]()
