C ES Literacy: 1., 1.2, 1.3, 1.5, 1.6, 1.7, 2.1, 2.6, 2.7, 3.4, 3.6, 3.7, 4.1, 5.2, 5.3, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, 8.1, 8.4, 8.5, 8.7, 8.81.Earth scientists use repeatable observations and testable ideas to understand and explain our planet.1.2 Earth scientists use a large variety of scientific principles to understand how our planet works.1.3 Earth science investigations take many different forms.1.5 Earth scientists use their understanding of the past to forecast Earth’s future.1.6 Earth scientists construct models of Earth and its processes that best explain the available geological evidence.1.7 Technological advances, breakthroughs in interpretation, and new observations continuously refine our understanding of Earth.2.1 Earth’s rocks and other materials provide a record of its history2.6 Life on Earth began more than 3.5 billion years ago.2.7 Over Earth’s vast history, both gradual and catastrophic processes have produced enormous changes.3.4 Earth’s systems interact over a wide range of temporal and spatial scales. C understand how multiple dating methods are used to construct the geologic time scale, which represents Earth's approximate 4.6-billion-year history 8.

B know that scientific hypotheses are tentative and testable statements that must be capable of being supported or not supported by observational evidence.

C use the school's technology and information systems in a wise and ethical manner. A know the definition of science and understand that it has limitations, as specified in subsection (b)(2) of this section; 2.

B explain how sedimentation, fossilization, and speciation affect the degree of completeness of the fossil record 8.

A analyze and evaluate a variety of fossil types such as transitional fossils, proposed transitional fossils, fossil lineages, and significant fossil deposits with regard to their appearance, completeness, and alignment with scientific explanations in light of this fossil data 8.

Key Terms: paleontology, evolution, fossilization, fossil record, index fossil, cross-cutting relationships, unconformities, fossil succession, rock superposition, original horizontality, geologic time, relative dating, speciation, mass extinction, adaptive radiation Standards: ESS TEKS: 1. C analyze changes in continental plate configurations such as Pangaea and their impact on the biosphere, atmosphere, and hydrosphere through time 1.

C evaluate the significance of the terminal Permian and Cretaceous mass extinction events, including adaptive radiations of organisms after the events 10. A compare the roles of erosion and deposition through the actions of water, wind, ice, gravity, and igneous activity by lava in constantly reshaping Earth's surface 11.

C know that scientific theories are based on natural and physical phenomena and are capable of being tested by multiple independent researchers.

Hypotheses of durable explanatory power which have been tested over a wide variety of conditions are incorporated into theories; 2.

B demonstrate an understanding of the use and conservation of resources and the proper disposal or recycling of materials; and 1.

A demonstrate safe practices during laboratory and field investigations; 1.

All of these fossils tell us something about the evolution of life on our planet and the evolution of the planet itself.
