"Drug Him Through the Street": Hughsey Childes Describes Turn-of-the-Century Sharecropping
The sharecropping system that emerged in the South in the last three decades of the 19th century afforded southern black families a certain measure of control over their daily lives and labor. But the white landowners were able to use the legal mechanisms of sharecropping to assure control over the largely African-American workforce that toiled on the farms. Here Hughsey Childes, interviewed by historian Charles Hardy in 1984, described what seems like a matter of fact exchange in which the whit
Chronos: a network for Earth system history
CHRONOS (Greek: time) aims to create a dynamic, interactive and time-calibrated framework for Earth history. CHRONOS's main objective is to develop a network of databases and visualization and analytical methodologies that broadly deal with chronostratigraphy - that is, with developing a better tool (the time scale) for understanding fundamental Earth processes through time. The CHRONOS platform will provide a new investigative environment for interdisciplinary Earth history research that includ
The Nancy Creek Challenge
The Nancy Creek Challenge is part of the Starting Point module. The Case study requires students to examine fish kill in Nancy Creek and identify the environmental conditions that favor life in a fresh water ecosystem. Students will work in small groups to assess the situation. The group will be allowed to gather resources from various places in an effort to develop a possible solution for the situation. The page also contains information regarding learning goals, context for use, teaching notes
Goodbye Honey Buckets
In this case study activity, students will investigate arctic geology and hydrology as well as tundra ecology and consider options for sewage treatment. Public safety, environmental impact, and issues of construction and engineering will be explored. This Starting Point example page builds on the Lifelines Online case study and includes learning goals, context for use, teaching notes and tips, teaching materials, assessment ideas, references and topics covered.
Starting Out With Earth History
This activity asks students to place 6-10 events in Earth history on a timeline, first working in small groups and then as a class. Then, through questions, important points such as how certain events are dated, where humanity fits in, and so forth, can be brought up. The Starting Point website builds a context for the exercise by detailing the learning goals, teaching notes and materials (downloadable), and additional resources.
For nearly half a century, Paul Nitze was one of the chief architects of U.S. policy toward the Soviet Union. In 1961, President John F. Kennedy appointed Nitze assistant secretary of defense for International Security Affairs. In this video segment, Nitze describes key issues confronting the incoming Kennedy administration. This transition period focused on the goals of the country's nuclear-strategic policy; how to approach crises in every region, from the Middle East to Vietnam; and whether t
Kissing Booth, The
Documentary-style piece in which four celebrities (Quentin Crisp -author, Emily XYZ -poet, Joe Morton -actor, Spider -musician) talk about kissing, seduction, relationships, love, sex, and romance in the U.S., England, and South Africa. Speakers muse about the subjects and talk about their own personal experiences. Shots of speakers talking directly to the camera are interspersed with straightforward and computer-enhanced scenes of couples kissing. Approximately 28 minutes in length.
Designer Genes for a Designer World
In this series of guided inquiry activities, students explore how organisms adapt to their environments through changes in their genetic codes. The learner will: create make-believe creatures and environments that have specific characteristics; rate the success of each creature in a randomly assigned environment by examining which of the creature's characteristics help, hinder, or have no effect on the creature's success in each environment; write the genetic code for their creatures from a lis
You will provide travel guidance to interplanetary travelers. You must ensure that travelers know enough about Mars to plan well, to know the best spots to visit, and at what time of year to visit them. You must become experts on Mars, so you can knowledgeably compare and contrast at most three possible resort locations on Mars to your customers. You need to know how to help travelers have safe and pleasant journeys and provide information they will need about Mars, about what they should take (
This is a series of computer animations which demonstrate all the possible combinations of the ideal gas law or equation of state. Gases have various properties which we can observe with our senses, including the gas pressure, temperature, mass, and the volume which contains the gas. Careful, scientific observation has determined that these variables are related to one another and the values of these properties determine the state of the gas. In a scientific manner, we can fix any two of the fou
Soil Science and Technology Home Page
This site looks at soil fertility, nitrogen in soil, soil chemistry, soils as electrical systems, soils as filters, soil physics and particle sizes (silt, sand, and clay), microorganisms in soil, nutrients that plants need, soil morphology, judging soil by feel, structures and shapes of soil, and soil profile images from Arizona, Florida, Michigan, and other states. Learn how soil is formed and how long it takes to create an inch of soil.
