EARTH SCIENCE - GEOLOGY - HISTORY OF THE EARTH

The last section of our geology unit covers chapters seventeen through nineteen in the text and introduces students to the geologic history of the earth. The study of the geologic record can be stimulating and provoking to those who are seriously engaged in the discussion. By examining the fossil record many students find there interpretations of such various topics as: dinosaurs, the age of the earth, catastrophism and sometimes their relegious assumptions challenged. By acknowledging the vastness of geologic time students may gain a clear insight as to their unique opportunity to exert extraordinary influence in the type of worl that will be studied by future generations by excercising their civic duties.

Idea's for further study: Compare and contrast uniformitarianism with catastrophism. Present personal beliefs, relegious teachings, as to how they compare with science's explanation for the age of the earth. Research the accuracy of commonly held beliefs as they relate to the fossil record. Present a two dimensional timeline that illustrates changes through geologic history. Compare the accuracy of relative dating vs. using radioisotopes. Research current periodicals and present the latest best thinking regarding establishing geologic age.

Mastery of the information presented in this section assists students in their preparation for F.C.A.T. testing by reinforcing the following Sunshine State Standards.

• Strand A, Standard 1: Understand that all matter has observable, measurable properties.
• Strand B, Standard 2: Understand the interaction of matter and energy.
• Strand C, Standard 1: Understand that types of motion may be described, measured and predicted.
• Strand C, Standard 2: Understand that the types of force that act on an object and the effect of that force can be described, measured, and predicted.
• Strand D, Standard 1: Recognize that processes in the lithosphere, atmosphere, hydrosphere and biosphere interact to shape the Earth.
• Strand D, Standard 2: Understand the need for protection of the natural systems on Earth.
• Strand G,  Standard 1: Understand the competitive, interdependent cyclic nature of living things in environment.
• Strand H, Standard 1:Use the scientific processes and habits of the mind to solve problems.
• Strand H, Standard 2: Understand that most natural events occur in comprehensible, consistent patterns.
• Strand H, Standard 3: Understand that science, technology and society are interwoven and interdependent.
