With these activities, students complete a sequence of tasks that require observation, measurement, and data analysis.Upon successful completion, they receive a personalized certificate.This page has links used in my NAGT Distinguish Speaker tour and NSF CCLI Workshop, most being to 3D perspectives about the the Geology of Arizona, Landscapes of the Southwest, structural geology, science-education reform, and using Bryce5 to illustrate geology.Most of these materials were built as part of the Hidden Earth and Hidden Earth Curriculum Projects, funded by NSF.Because this assignment is linked with your work in Assignment 3, you will have "If Scientists Think. Before scientists had modern technology to assist them in their research, they had to use their power of observation to infer the relative ages of the rocks they were studying.The process of Relative Dating was established by Nicholaus Steno in the 1600's.Steno developed a set of Laws (Steno's Laws) to help explain his method of inferring the ages of geological structures.These laws are a set of hypotheses that the scientific community accepts as a starting basis without absolute proof.
Movies Created by Draping Satellite Images over Digital Topography Warning -- some of these files are large -- look before you leap.In Assignment 3, we began exploring the age of the Earth. Through presentation and discussion of individual ideas, the class reached agreements as to the best way to complete each of the prompts.You worked in small groups and as a class to complete the "If Scientists Think. Today's assignment will allow you to compare and contrast your ideas to some of the actual methods scientists used to develop an estimation of the age of the Earth.In the 19th century some geologists realized that the vast thicknesses of sedimentary rocks meant that the Earth must be at least hundreds of millions of years old.Charles Darwin reinforced this idea by pointing to the time that must have been required for the EVOLUTION of advanced life from primitive forms.
