Jurisdiction in Cyberspace
At its core, jurisdiction is about the boundaries of a sovereign's exercise of its power. What are reasonable constraints on its reach, such that faraway or otherwise unconnected people and institutions can be called to account by the sovereign? Closely related are concepts of choice of law - exactly which sovereign's law to apply to a situation that spans multiple jurisdictions - and venue, which determines the physical location in which the parties are best served to settle their dispute. The
Tropospheric Ozone and Smoke from Earth Probe TOMS: Indian Ocean to Indonesia Zoom
Researchers have discovered that smoke and smog move in different ways through the atmosphere. A series of unusual events several years ago created a blanket of pollution over the Indian Ocean. In this animation, significant smog or tropospheric ozone is represented by red and green and regions of significant smoke index are in shades of white and gray.
GLOBE 1987 Global Patterns Poster
The purpose of the ESS activities associated with the GLOBE 1987 Global Patterns Poster is to help students understand the broader global context for local GLOBE measurements. Students discover patterns in global maps of environmental data, interpret those patterns, and draw conclusions and make predictions based on them; communicate those interpretations and predictions; and develop an understanding that the components of the Earth system interact. By completing this activity, students will gai
Elementary GLOBE: Water Wonders
Students will be introduced to different species of macroinvertebrates. They will hypothesize why each insect looks the way it does. Then students will make observations of macroinvertebrates. in an aquarium in their classroom. For an optional extension, teachers can take students to a local stream or pond to conduct field observations. The purpose of this activity is to introduce students to hydrology and the study of macroinvertebrates. and to understand how macroinvertebrates. help scientists
Elementary GLOBE: The Colors of the Seasons
Using a color chart, students will make observations outside during each of the four seasons. During each session, they will try to find as many colors as possible and record what they see. As a class, they will make charts describing the colors they find in each season. At the end of the school year, students will compare their results and generate conclusions about variations in colors in nature both within a season and between different seasons. The purpose of this activity is to provide the
This site features dozens of online learning activities and exhibits. Make a mold terrarium, pinhole projector, telescope, or hair hygrometer. Explore the brain, biodiversity, Antarctica, DNA, frogs, structures, or illusions. Learn about magnetism, electricity, motors, eyeballs, perception, Mars, chocolate, seasonings, or the science of cooking, sports, and music. Search over 3,000 photos and movies. Watch webcasts of science demonstrations by teachers.
Lets us look over the shoulders of scientists and glimpse the often-unseen moments of investigation. Take virtual field trips to eight observatories -- Arecibo, where astrobiologists search for signs of life beyond the solar system; Las Cuevas, a research station in Central America's largest remaining rainforest; and others. See interviews, photos, and broadcasts that explore the origins of matter, the universe, and life itself.
What is Inquiry?
Good science education requires both learning scientific concepts and developing scientific thinking skills. Inquiry is an approach to learning that involves a process of exploring the natural or material world, and that leads to asking questions, making discoveries, and testing those discoveries in the search for new understanding. Inquiry, as it relates to science education, should mirror as closely as possible the enterprise of doing real science.
Earth Exploration Toolbook Chapter: Analyzing Wetlands
The Ramsar Wetlands Data Gateway is a database containing information on protected international wetlands. In this activity, users search the database to find a wetland that they are interested in helping to protect. Using the database search capabilities, users select various wetland characteristics and generate a report on the sites that meet their search criteria. Then, they access an interactive map to view the locations and nearby features of the identified wetland sites. Next, they narrow
Earth Exploration Toolbook Chapter: Investigating the Precipitation-Streamflow Relationship
This activity prepares you to launch an investigation of the relationship between precipitation and streamflow for a local watershed. It can enrich a study of the water cycle. Following the step-by-step instructions in a case study you will locate, download, format, and finally graph one year of Web-based data for these two variables. The graph highlights the details of this often complex precipitation-streamflow relationship and provides a context for launching a classroom discussion of the bal
HazDat, the Agency for Toxic Substances and Disease Registry's (ATSDR) Hazardous Substance Release/Health Effects Database, is the scientific and administrative database developed to provide access to information on the release of hazardous substances from Superfund sites or from emergency events and on the effects of hazardous substances on the health of human populations. The following information is included in HazDat: site characteristics, activities and site events, contaminants found, cont
Methods in Science
Effective science instruction is a key component of any course of study for students in the elementary school. This course will provide a basis for-pre-service teachers to gain awareness of national, state, and local standards in science education, as well as, effective teaching strategies that will help teachers meet the various needs of all learners in the public school setting.
Herschel Infrared Experiment
Students perform a version of the 1800 experiment in which a form of radiation other than visible light was discovered by the famous astronomer Sir Frederick William Herschel.
The American Jury: Bulwark of Democracy
"The American Jury: Bulwark of Democracy" is a project of the Constitutional Rights Foundation Chicago and is the national expansion of "The American Jury: Past and Present," conducted in Illinois during 1998-1999. Beginning with a two-week institute in July 1999, "The American Jury" focused on the jury system in the United States. its role in American legal, social, and political life; its origins and history; its adaptations to changes in law and American society; its strengths and limitations
Community Organizing Toolkit Game
The Toolkit is a set of resources that supports face-to-face training for residents and community leaders. The computer-based component (the "Organizing Game") is used to introduce concepts, prompt discussion, and allow residents to practice skills in a safe, non-threatening environment. The initial focus of the Toolkit is teaching Doorknocking, an organizing technique that's particularly effective in moving issues within a local community.
