Skulls : structure and function
Skulls have been designed for both form and function. Through the use of text and labeled photographs, this website explains how specific skull adaptations meet the needs of organisms. For instance, visitors will discover that some beaks of macaws are attached to their skull only through ligaments to limit the amount of force put on the skull when the birds crack open nuts. The site also presents a series of skull facts, questions, and answers provided by scientists. A unique feature allows visi

Lessons on the Lake : An Educators Guide to the Ponchartrain Basin
This resource is designed to educate students, through activities teachers can use, about the environmental importance of Lake Ponchartrain. The main goal is to foster a sense of stewardship in students through learning to identify environmental issues that affect the lake, offer changes, and develop solutions. Although the resource deals with the Lake Ponchartrain Basin, the activities are applicable to students and teachers beyond this local level. The activities and lesson plans cover everyth
The Pythagorean Theorem
This math site has students try to figure out the Pythagorean Theorem by themselves. Included are review pages, five clues to help them find the relationship, a section that compares their results to other students, a section that gives historical information, and examples and activities for students to solve. Each clue page allows students to check to see if they have the formula correctly relating to the three sides of the right triangle. A template page that contains figures used in three of
Testing, Teaching, and Learning: A Guide for States and School Districts
State education departments and school districts face an important challenge in implementing a new law that requires disadvantaged students to be held to the same standards as other students. The new requirements come from provisions of the 1994 reauthorization of Title I, the largest federal effort in precollegiate education, which provides aid to level the field for disadvantaged students. Testing, Teaching, and Learning is written to help states and school districts comply with the new law, o
This interactive planetarium can create sky maps for a given location and a given time. Once the latitude and longitude of the desired area is entered, the Web site creates a map of the sky. The names of cities can be entered in place of longitude and latitude.
Observe a lunar eclipse
This Earth science animation enables middle and high school students to observe the events of a lunar eclipse. The introduction explains why the moon's appearance changes as is moves through the Earth's shadow. The animation shows the moon darken as it enters the penumbra, turn reddish-orange as it reaches the umbra, and lighten as it leaves the other side of the penumbra. Movie controls allow students to repeat, pause, or step through the animation, which can give students more time to analyze
Miss Lindquist: The Tutor
A free Web tutoring system for middle school and high school students concentrating on writing expressions for algebra word problems. Teachers can assign portions of this site for homework, students can get help as they do their homework, and progress reports can be sent to a teacher's e-mail address. The program randomly selects problems from the section that the student is working on, e.g.: One-operator problems; harder one-operator probems involving speed, distance, and time; easier two-opera
How much does the United States depend on fossil fuels? This web page, part of a site on the future of energy, introduces students to fossil fuels as an energy source. Here students read about the uses, benefits, and limitations of fossil fuels. There is also information on how these fuels are distributed geographically and how they affect the U.S. economy through supply and demand. Thought-provoking questions afford students opportunities to reflect on what they've read. Articles about clean co

National Oceanic and Atmospheric Administration : Research Homepage
National Oceanic and Atmospheric Administration (NOAA) Research, conducted primarily through the NOAA Office of Oceanic and Atmospheric Research, drives the NOAA environmental products and services that protect life and property and promote sustainable economic growth. Research, conducted by in-house laboratories and by extramural programs, focuses on enhancing understanding of the environmental phenomena such as tornadoes, hurricanes, climate variability, solar flares, changes in the ozone, El
This is the introductory page for a set of materials about agronomy as a career. A general description of the work done by agronomists is first provided. In the rest of the resource, students can read narratives about a field sales agronomist and a crop production specialist. Each of these agronomists has provided a challenge activity for students. In one activity, students make brochures and suggest reasons why their sales company is better than a competitor's. Another activity asks students to
Degrees Kelvin: A Tale of Genius, Invention, and Tragedy
LORD KELVIN. In 1840, a precocious 16-year-old by the name of William Thomson spent his summer vacation studying an extraordinarily sophisticated mathematical controversy. His brilliant analysis inspired lavish praise and made the boy an instant intellectual celebrity. As a young scholar William dazzled a Victorian society enthralled with the seductive authority and powerful beauty of scientific discovery. At a time when no one really understood heat, light, electricity, or magnetism, Thomson fo
Data Analysis and Measurement: Ahead, Above the Clouds
This is the Educator Guide of an archived NASA (National Aeronautics and Space Administration) CONNECT program designed to help students discover that in predicting severe weather and tracking clouds, NASA engineers and scientists are developing technologies to collect data that will help them better understand Earth's climate. The guide includes an activity in which students play a game that will help them understand the complexity of hurricane forecasting. They will be given the coordinates fo
Cold Clouds and Water in Space
This article from Astrobiology Magazine reports on the discovery of water in cold regions of space. Using data from the European Space Agencys Infrared Space Observatory, astronomers have determined that water is abundant in these cold, or quiescent regions of space where there are no stars, and that the majority of it occurs as ice with a small amount of water vapor. It is thought that these cold regions of space might be the future birthplaces of low-mass stars like our own sun. Links to other
