What is being measured in radiometric dating
2) To familiarize students with the concept of half-life in radioactive decay.
Understanding the ages of related fossil species helps scientists piece together the evolutionary history of a group of organisms.
Since he had discovered an unknown species, he took the liberty of naming it in an 1894 publication.
He called it Dubois' claims for his Java Homo erectus finds were not widely accepted until the 1930's, when the German/Dutch paleontologist Gustav von Koenigswald made similar discoveries in the Dutch East Indies.
It is estimated to require four hours of class time, including approximately one hour total of occasional instruction and explanation from the teacher and two hours of group (team) and individual activities by the students, plus one hour of discussion among students within the working groups.
Explore this link for additional information on the topics covered in this lesson: This activity will help students to have a better understanding of the basic principles used to determine the age of rocks and fossils. Objectives of this activity are: 1) To have students determine relative age of a geologically complex area.By that time, there had also been even more convincing discoveries of Homo erectus in China.
