The learning objectives in this section will help your students master the following standards:. Unstable nuclei decay. However, some nuclides decay faster than others. For example, radium and polonium, discovered by Marie and Pierre Curie, decay faster than uranium. That means they have shorter lifetimes, producing a greater rate of decay.

The problem : By the mid 19th century it was obvious that Earth was much older than years, but how old? This problem attracted the attention of capable scholars but ultimately depended on serendipitous discoveries. Early attempts : Initially, three lines of evidence were pursued: Hutton attempted to estimate age based on the application of observed rates of sedimentation to the known thickness of the sedimentary rock column, achieving an approximation of 36 million years.
In Assignment 3, we began exploring the age of the Earth. You worked in small groups and as a class to complete the "If Scientists Think. Through presentation and discussion of individual ideas, the class reached agreements as to the best way to complete each of the prompts. 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.
