In this activity, students in groups of three will construct a vertical representation of a Geologic Time Scale and research facts, events, and organisms that differentiate between Time Scale Eras, Periods, and Epochs.
Paleo Sleuth Investigations, or PSI, includes four activities to be used in succession that focus around fossils in Nebraska and the Ashfall Fossil Beds State Historical Park located north of Royal, Nebraska. Each PSI engages students to explore fossils, the work of paleontologists in discovering, analyzing, and recording fossil evidence, and the environmental conditions of the earth at the time of fossil deposition.
This is an inquiry activity that will introduce students to the variety of fossils that can be found at Ashfall Fossil Beds State Historical Park located north of Royal, Nebraska. Students will use what they have learned about describing fossils from previous activities to infer information, and identify cardstock representations of fossils to that of the real fossils found at Ashfall through research on the Ashfall website. Students will have four excavation opportunities to investigate and identify the animals at Ashfall. This activity takes 1-2 days to complete. This activity is an adaptation of the Great Fossil Find.
Students, as preparators, will make a fossil field jacket using a seashell fossil. Seashells are used because they are larger to manage for this activity and can be ordered in a larger quantity. Other fossils or rocks can be used depending on the size. Palm size is recommended. They will only cover the topside of the seashell fossil or other fossil in this activity.
