The Online Books Page
Hosted by the University of Pennsylvania Library, the Online Books Page Web site "facilitates access to books that are freely readable over the Internet...and aims to encourage the development of such online books, for the benefit and edification of all." The over 18,000 listings can be searched or browsed by author, title, and subject, of which every major physical science subject is represented. Each listing is linked to an outside Web site, making its availability unpredictable, but the shear
The AgNIC Dairy Information Center
The AgNIC (Agriculture Network Information Center) Dairy Information Center -- "a guide to quality information on the Internet" -- is a new open-access Web portal from the University of Wisconsin's Steenbock Library. The site is intended for "researchers in the field of dairy science, for farmers and others who raise dairy cattle, and for students of all ages interested in dairy." Users may easily browse the guide by navigating the website's nested categories, or simply search the entire site by
National Environmental Data Index
The National Environmental Data Index is maintained by the National Atmospheric and Oceanic Administration Environmental Information Service. The service provides a full text search of information from twelve governmental agencies including the US Department of Agriculture, Department of Energy, Department of Interior, Environmental Protection Agency, and NASA. Users can choose to search from all or individual agencies, by type of information, and by several specific subjects. Results display th
Study of Menopausal Women with Heart Disease Finds No Benefit, Potential for Harm from Hormone Thera
This site describes a study sponsored by the National Heart, Lung, and Blood Institute, which found that postmenopausal women with heart disease did not benefit from high doses of antioxidants vitamins, whether alone or in combination with hormone replacement therapy. In fact, researchers found both treatments to be potentially harmful.
Geophysical Studies of the Las Vegas Urban Corridor
The Geophysical Studies of the Las Vegas Urban Corridor Area are part of an integrated effort to "geologically characterize the seismic hazards, water resources, and crustal structure of this rapidly growing urban corridor" by the USGS. The informational Web site contains a gravity map of the Las Vegas region, an aeromagnetic map, and a publications link with a list of over a dozen references. Seven of these publications are freely available for download with titles such as "Aeromagnetic Survey
GLOBIO: Mapping human impacts on the biosphere
A joint project of the Norwegian Institute for Nature Research and the United Nation's Environmental Programme, Global Methodology for Mapping Human Impacts on the Environment (GLOBIO) aims to "present a simple visual overview of the cumulative impacts of increasing resource demands on man and the environment." Hundreds of environmental impact studies were synthesized with satellite imagery, infrastructure data, etc. to create this "visual overview" of past, current, and potential future conditi
PicSNP: A Catalog of Non-Synonymous SNP
Maintained by Hangil Chang at the University of Tokyo, PicSNP "is a catalog of non-synonymous Single Nucleotide Polymorphism (SNP) in the human genome." Recently updated, the database allows users to select SNPs by gene name, function of affected genes, biological process relevant to affected genes, or cellular component that contain affected genes. The site does not include much instruction on how to use the database, meaning it is most suitable for users who are familiar with the subject.
YES Mag: Science Projects
Parents, are you looking for a way to excite your children about science? This website developed by YES Mag, Canada's science magazine for kids, may just have the answer. Users can find numerous fun science activities addressing many of the basic science principles and phenomena including Newton's third law, lightening, wind, and chromatography. Each activity includes pictures to assist in the implementation of the project as well as a convenient printable version. With over thirty-five activiti
Hangman: Characteristics Of Matter
The Quintessential Instructional Archive (QUIA) Web site (last mentioned in the July 13, 2001 Scout Report) contains fun, online science-related activities. The Characteristics Of Matter hangman game was created by students to test your knowledge of matter in the universe. Users can choose individual letters to see if they're right; if not, another body part appears on the hangman illustration. Puzzles include hints such as "Changes from a liquid to a gas" and "A change in which a new substance
Symmetry and Tessellations
This website provides 30 suggested activities in Symmetry and Tessellations using resources available across the World Wide Web. The author, Jill Britton, has complied this collection of links to coordinate with the chapters and activities from her publication, Investigating Patterns: Symmetry and Tessellations (Grades 5-8). The activities begin with What is Mathematics? and move on to cover topics such as Pythagoras? observations of music, patterns on Ukrainian Easter eggs, and tessellating art
Solar System Trading Cards
The students will collect solar system trading cards by playing an interactive card game. They will identify the sun, planets, comets, and asteroids by answering questions about them. By playing the game, students will gain knowledge about the solar system and they will view pictures taken by the Hubble Space Telescope and other NASA missions. Students will view an image accompanied by a question with three responses. By using the computer mouse, they will chose an answer. When the response is c
Hot Colors- Windows into Hidden Worlds
This website contains an electronic field trip based on Yellowstone National Parks hot springs and the microorganisms living in them. The site includes a link for teachers providing an introduction, overview of concepts explored in the trip, lesson plans, and additional web links. The electronic field trip may be viewed in a low bandwidth version without downloading. For a high bandwith version of the field trip, Macromedia Flash Player is required and can be downloaded on site. Further informat
4.1 Introduction
Optical-fibre communications became commercially viable in the 1970s and innovation continues today. This unit will illustrate how very high data rates can be transmitted over long distances through optical fibres. You will learn how these fibres are linked, examine the technology used and assess the future direction of this continually developing area of communication.
We’ve Come a Long Way, Baby!
Students discuss several human reproductive technologies available today — pregnancy ultrasound, amniocentesis, in-vitro fertilization and labor anesthetics. They learn how each technology works, and that these are ways engineers have worked to improve the health of expecting mothers and babies.
Mini-Landslide
Students explore how different materials (sand, gravel, lava rock) with different water contents on different slopes result in landslides of different severity. They measure the severity by how far the landslide debris extends into model houses placed in the flood plain. This activity is a small-scale model of a debris chute currently being used by engineers and scientists to study landslide characteristics. Much of this activity setup is the same as for the Survive That Tsunami activity in Less
Stack It Up!
Students analyze and begin to design a pyramid. Working in engineering teams, they perform calculations to determine the area of the pyramid base, stone block volumes, and the number of blocks required for their pyramid base. They make a scaled drawing of the pyramid using graph paper.
Where Am I: Navigation and Satellites
How do we know where we are? What happens if you are completely lost in the middle of nowhere? Does technology provide tools for people lost in their travels? A person cannot usually determine an accurate position just by looking out a window in the middle of the ocean or vast area of land, particularly if it has not been charted before. In this lesson, students explore the concept of triangulation that is used in navigation satellites and global positioning systems designed by engineers. Also,
Bombs Away!
Students will design and build a device to protect and accurately deliver a dropped egg. The device and its contents represent a care package that must be safely delivered to people in a disaster area with no road access. In a similar fashion to a team of design engineers, students will design their devices using a number of design constraints including limited supplies. The activity emphasizes the change from potential energy to kinetic energy of the device and its contents and the energy trans
