Gavrilo Princip assassinated Austro-Hungarian Archduke Franz Ferdinand, setting off World War I. Created by Sal Khan.

The artist conveys some of the profound disappointment and anger among Henry Clay's many supporters at the nomination of Zachary Taylor at the June 1848 Whig convention in Philadelphia. The convention's act was seen as a betrayal of the elder Whig statesman. In a scene based on act 3, scene 1 of Shakespeare's "Julius Caesar," the artist portrays Clay's opponents as treacherous conspirators stalking the unsuspecting statesman. Clay is pictured seated in the library of his estate at Ashland in Kentucky, reading the New York "Tribune," whose editor Horace Greeley was a Clay stalwart. Ten men with raised daggers prepare to attack him from behind. These include various Whig powers Daniel Webster, editor James Watson Webb, former New York mayor William V. Brady, Pennsylvania congressman David Wilmot, Kentucky senator and former Clay ally John J. Crittenden, and New York state party boss Thurlow Weed. Webster: "How many times shall Caesar bleed in sport" Webb: "Liberty! Freedom! Tyranny is dead!!!" Wilmot: "Go to the Pulpit Brutus" Brady: "And you too Cassius" Crittenden: "Stand fast together, lest some friend of Caesar's Should Chance" Weed: "By the necessity of my Nature, Your Enemy".|Drawn by "W.J.C."|Entered . . . 1848 by H.R.

This curriculum, which may be used in whole or in part, offers an overview of foster care, background on the characteristics of kin and non-kin foster parents, and trends in foster care. Special emphasis is placed on foster care recruitment, training, and retention efforts as well as the foster care payment rate structure. A comprehensive look at the elements that comprise quality of care in kinship and non-related foster homes is included. The curriculum highlights the philosophical reasons for providing quality care, the history and philosophy of kinship care, a legal history and brief policy analysis of kinship care, and domains of quality. Practice tips for child welfare workers and administrators are included, as well as a chapter where kin and non-kin foster parents address their relationship with the child welfare system and recent child welfare policies affecting foster parents and kinship caregivers.

This is an assignment appropriate for introductory sociology courses. Students watch a webinar, "I Am George Floyd," summarize and react to it, and apply sociological concepts and/or theories.

The battle of Til Tuba reliefs are among some of the great masterpieces of ancient Assyrian art. The movement and details are truly stunning. That said, the scenes actually being depicted are anything but easy on the eye. Join curator Gareth Brereton as he walks you through the reliefs that once decorated the last great king of Assyria's royal palace. WARNING: includes scenes of drowning, flaying and wearing your deceased leader's head as a necklace. DOUBLE WARNING: includes scenes of extreme royal hat misplacement.

Astronomy Notes is a website with a brief overview of astronomy's place in the scientific endeavor, the philosophy of science and the scientific method, astronomy that can be done without a telescope, a history of astronomy and science, Newton's law of gravity and applications to orbits, Einstein's Relativity theories, electromagnetic radiation, telescopes, all the objects of the solar system, solar system formation, determining properties of the stars, the Sun, fusion reactions, stellar structure, stellar evolution, the interstellar medium, the structure of the Milky Way galaxy, extra-galactic astronomy including active galaxies and quasars, cosmology, and extra-terrestrial life. This site also has pages giving angular momentum examples, a quick mathematics review, improving study skills, astronomy tables, and astronomy terms

This downloadeable resource guide, for instructors and students in introductory astronomy courses, focuses on the contributions to astronomy of African, Asian, Hispanic, South Pacific, Islamic, and Native American cultures. It also contains a section on reports and articles for achieving greater diversity in science. Written by Andrew Fraknoi, the guide is part of a series sponsored by the Heliophysics Forum of the Space Missions Directorate at NASA. It includes written, on-line, and audio-visual materials, which can be used directly in the classroom, for student papers, or for personal enrichment.

Intended for all audiences, this textbook is an introduction to the nature of the universe. Use it to research or review our solar system, stars, galaxies, and the history of the universe. Each chapter has a set of corresponding homework questions.

Speakers: Dr. Steven Zucker and Dr. Beth Harris. Created by Steven Zucker and Beth Harris.

In this activity, students explore the web-based U.S. Forest Service Climate Change Atlas to learn about projected climate changes in their state and how suitable habitat for tree and bird species is projected to change by 2100.

Short Description:
The goal of this Renal Pathology Atlas is to provide teaching material to veterinary pathologists and nephropathologists. The atlas demonstrates the breadth of lesions that can occur within a cohort of dogs presenting with the clinical sign of protein loss in the urine. Kidney samples were examined with multiple modalities including: histopathology, immunofluorescence and electron microscopy. Integration of these comprehensive evaluations with the clinical history can help veterinary pathologists and nephrologists to better understand the etiology and prognosis of renal lesions in proteinuric dogs.

Explore climate change on a geologic time scale, and consider recent human impacts on climate and the atmosphere. Created by Big History Project.

This course explores the physical processes that control Earth's atmosphere, ocean, and climate. Quantitative methods for constructing mass and energy budgets. Topics include clouds, rain, severe storms, regional climate, the ozone layer, air pollution, ocean currents and productivity, the seasons, El Ni–o, the history of Earth's climate, global warming, energy, and water resources.

These graphs show carbon dioxide measurements at the Mauna Loa Observatory, Hawaii. The graphs display recent measurements as well as historical long term measurements. The related website summarizes in graphs the recent monthly CO2, the full CO2 Record, the annual Mean CO2 Growth Rate, and gives links to detailed CO2 data for this location, which is one of the most important CO2 tracking sites in the world.

This is a multi-step activity that helps students measure, investigate, and understand the increase in atmospheric CO2 and the utility of carbon offsets. It also enables students to understand that carbon offsets, through reforestation, are not sufficient to balance increases in atmospheric C02 concentration.

This image depicts a representative subset of the atmospheric processes related to aerosol lifecycles, cloud lifecycles, and aerosol-cloud-precipitation interactions that must be understood to improve future climate predictions.

This is a figure from the 2007 IPCC Assessment Report 4 on atmospheric concentrations of carbon dioxide, methane and nitrous oxide over the last 10,000 years (large panels) and since 1750 (inset panels).

Atmospheric methyl chloroform concentration is modeled as an extension of the generic water tank structure. Simulated and observed concentrations are used to estimate the global atmospheric lifetime of methyl chloroform and its 1989 to 2009 emission history.
