Following this introduction, there are several links to different sites concerning the methods scientists use to assist them in estimating the age of the Earth.You will investigate Steno's Laws, radiometric dating, and then visit an interactive site that will help you better understand how to tell time - with geology! As you proceed through Assignment 4, be sure to compare your answers from "If Scientists Think. ." to the actual methods scientists use to estimate the age of prehistoric objects.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.This is a relatively long activity so stay focused on your work.
The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results.To obtain further practice with the concepts of Steno's laws and geologic dating, work through the Understanding Geological Time section of this assignment.This portion of the assignment is an interactive web site that allows you to apply what you have learned and to learn more about how scientists tell time with geology.Keep these principles in mind as you progress through the rest of the activities in this assignment.It would benefit your understanding of this material if you studied the rest of this website on your own, but it is not required for class.
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.
