Civil Rights Movement Timeline (14th Amendment, 1964 Act, Human Rights Law) Jan. 23 The 24th Amendment abolishes the poll tax, which originally had been instituted in 11 southern states after Reconstruction to make it difficult for poor blacks to vote. Summer The Council of Federated Organizations (COFO), a network of civil rights groups that includes CORE and SNCC, launches a massive effort to register black voters during what becomes known as the Freedom Summer. It also sends delegates to the Democratic National Convention to protest—and attempt to unseat—the official all-white Mississippi contingent. July 2 President Johnson signs the Civil Rights Act of 1964. Aug. 4 (Neshoba Country, Miss.)
Prehistory Prehistory (meaning "before history", or "before knowledge acquired by investigation", from the Latin word for "before," præ, and historia) is the span of time before recorded history or the invention of writing systems. Prehistory refers to the period of human existence before the availability of those written records with which recorded history begins.[1] More broadly, it can refer to all the time preceding human existence and the invention of writing. The notion of "prehistory" began to surface during the Enlightenment in the work of antiquarians who used the word 'primitive' to describe societies that existed before written records.[2] The first use of the word prehistory in English, however, occurred in the Foreign Quarterly Review in 1836.[3] The occurrence of written materials (and so the beginning of local "historic times") varies generally to cultures classified within either the late Bronze Age or within the Iron Age.

Fossils and Geologic Time Photo Credit: Clipart.com Purpose To help students understand the development of the geologic time scale. Also, to introduce students to the major time periods in earth's history, as well as to the role fossils play in helping us understand this history. Context This lesson is based on an online booklet that provides an introduction to the study of earth's history, published by the USGS. Students will likely have been introduced to the geologic time scale in earlier grades, so this lesson is structured loosely to enable you to adapt the content to match the levels and needs of your particular students. Concepts covered in this lesson, including geologic history, age dating, plate tectonics, timelines, and fossils are prerequisite concepts for understanding the theory of evolution, which is another topic taught at this grade level. Planning Ahead This lesson is based on information included in Fossils, Rocks, and Time, part of the United States Geological Survey website. Motivation Development
Hadean: Overview The name Hadean Eon comes from Hades, the underworld of Greek mythology. It refers to the “hellish” conditions of the Earth during the earliest part of its history, when much of the Earth’s surface remained molten. The Hadean Eon of geologic time began with the birth of the solar system, including our planet, Earth, and ended with the formation of the oldest rocks that are still preserved on the surface of Earth. The Hadean is the first period in Earth history, but one for which we have little record. The Earth began to form about 4.6 billion years ago through the condensation of material around the sun. As this material collected, further cosmic material was drawn to it by gravity from all directions, increasing the size of the Earth.

Geology Entrance You might wish to start in the Cenozoic Era (65 million years ago to the present) and work back through time, or start with Hadean time (4.5 to 3.8 billion years ago) and journey forward to the present day. No matter "when" you start, don't forget to stop along the way to learn about the stratigraphy, ancient life, fossil localities, and tectonics of the various time periods. Here are three links that can help to speed your journey: 1) Get helpful hints on navigating the Geology Wing. 2) Read about the history of the geologic time scale, and find out more about how it is organized. 3) Jump to a specific time period using the UCMP Geological Time Machine. Last but not least, don't forget to visit our exhibit on Plate tectonics, an important geological concept in any time period!
Cenozoic Era Cenozoic Era (65 million years ago to present) The KT Event set the stage for the Cenozoic Era Cenozoic Era that began 65 million years ago. As the dinosaurs perished at the end of the Cretaceous, the mammals took center stage. Even as mammals increased in numbers and diversity, so too did the birds, reptiles, fish, insects, trees, grasses, and other forms of life. Species changed as the epochs of the Cenozoic Era rolled by, with the mammals eventually becoming the largest land animals of the Era, as the dinosaurs had been during the Mesozoic. Tertiary Period (65 to 2.6 million years ago); Also see: Tertiary Fossils Invertebrates, fish and reptiles were similar to those of modern types, but mammals, birds, protozoa and flowering plants would undergo considerable evolutionary change. Paleocene - The Paleocene Epoch began after the extinction of the dinosaurs. Eocene - The first grasses appeared in the Eocene Epoch (from about 54 to 37 million years ago) with growth near the root
Brief Timeline of American Literature and Events, 1620-1920 Brief Timeline of American Literature and Events: Pre-1620 to 1920 This timeline provides a short chronology of events in American history and literature. It is linked to course pages and bibliographies as well as to a set of more general linked resources: pages on American authors, literary movements, and American literature sites. Each author page contains a picture (if available), a bibliography (if available), links to major sites about the author, and links to works online.
Geologic time scale The geologic time scale (GTS) is a system of chronological measurement that relates stratigraphy to time, and is used by geologists, paleontologists, and other earth scientists to describe the timing and relationships between events that have occurred throughout Earth's history. The table of geologic time spans presented here agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy. Evidence from radiometric dating indicates that the Earth is about 4.54 billion years old. The geology or deep time of Earth's past has been organized into various units according to events which took place in each period. Different spans of time on the GTS are usually delimited by changes in the composition of strata which correspond to them, indicating major geological or paleontological events, such as mass extinctions.
