EERI/IAEE World Housing Encyclopedia
This online Encyclopedia of Housing Construction Types is a joint project between two prominent earthquake engineering organizations. It is intended to help engineers make buildings in regions of high seismic activity less susceptible to damage, and hopefully save lives. A large amount of housing information is given for many different countries. Hazard maps show areas that are most at risk. Building descriptions describe common construction types and structural features, and suggest seismic str
aspectj.org: Crosscutting Objects for Better Modularity
AspectJ is a Java extension with aspect-oriented functions and programming technology. Continuing with the open source movement, the developers have made AspectJ free for download from this Web site. The software implements "the clean modularization of crosscutting concerns" like performance optimizations, debugging support, and more. The compiler, several accompanying tools, and example programs are all provided in the release. There is also extensive documentation and a tutorial to help new us
MIT Space Systems Laboratory
Massachusetts Institute of Technology (MIT) created the Space Systems Laboratory (SSL) in 1995 to engage in "cutting edge research projects with the goal of directly contributing to the present and future exploration and development of space." Users can find materials on current and past flight projects such as the Synchronized Position Hold, Engage, Reorient Experimental Satellites (SPHERES) and the Interferometry Program Experiment (IPEX). The website also features SSL's ground programs and re
Learning math : Measurement
This college level course, developed for elementary and middle school teachers, begins with the fundamentals of measurement, then examines standard units in the metric and customary systems. Online workshop sessions cover measurement of a circle, area and volume formulas, angle measurement, and indirect measurement encountered in trigonometry. The final session explores ways to apply these concepts to K-8 classroom teaching. Each of its ten sessions contains video programming, problem-solving ac
Looking at the sky through a glass ceiling : women in astronomy
This article looks at the involvement and acceptance of women in astronomy. Before introducing readers to three significant female astronomers from the 1900s and three from the present day, the article mentions the work of the first known female astronomer--Aglaonike from 200 B.C. Statistics are also provided concerning contemporary women's participation in astronomy. The three astronomers featured from the 1900s are Henrietta Swan Leavitt, Cecilia Payne-Gaposchkin, and Jocelyn Bell Burnell. Eac
Who Needs Algebra? Everyone! : Northwest Teacher, volume 6 number 1
Learning algebra doesn't have to be painful, and researchers are finding that the process is easier if children are introduced to algebraic reasoning early on. This issue of NW Teacher points out that students who begin learning algebra at the elementary level have a stronger foundation for higher-level mathematics. Algebra also helps pave the way for college and increased career opportunities. This issue helps schools explore new ways of bringing algebra to all students.

Blue Planet: Sea Vent Photo Gallery
These nine "sea vent" inhabitants were captured on film with a Woods Hole Oceanographic Institution high definition underwater imaging system from the Deep Submergence Vehicle Alvin. A description of each animal is provided. The vent is in the Pacific about 1,000 miles south of San Diego, California.
T.P. Away
What's a quick way to unroll a roll of toilet paper? This material is part of a series of hands-on science activities designed to arouse student interest. Here students use Bernoulli's principle and an electric leaf blower to force air over the top of the toilet paper to quickly unroll it. The activity includes a description, a list of science process skills and complex reasoning strategies being used, and a compilation of applicable K-12 national science education standards. Also provided are c
Science Sampler : Reading science
Nonfiction books have the power to excite students about learning and fuel their desire to know more about a topic or person. Using a variety of books can differentiate instruction and provide suitable reading to students at all levels and for almost any interest. This article provides a list of recommended reading and some lesson ideas that correspond with the material.
How ozone is made
How does ozone in the upper atmosphere help protect life on Earth? This informational piece, part of an interactive laboratory series for grades 8-12, explores the production and destruction of ozone in the upper atmosphere. Here students view an animation of ultraviolet light breaking an oxygen molecule to form ozone and then the ozone splitting when struck by ultraviolet light. Text explanations are provided along with chemical equations. Copyright 2005 Eisenhower National Clearinghouse
Energy in-depth timeline
The history of energy usage provides an interesting view of the development of technology over time. This informational piece, part of a series on the future of energy, introduces students to the advancement of technology through the use of energy. Students read how energy needs and uses have affected the production of power, manufacturing industries, and transportation methods. This piece focuses on energy systems based on fossil fuels, geothermal, hydrogen, nuclear, solar, and wind energy, and
4.3 Optical networking
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.
Decarteret matches pole vault record at Florida State
The Northeastern women's track & field team recorded 15 top-10 marks, including another record-breaking performance by Jillena Decarteret, amidst stiff competition at this weekend's Florida State Relays in Tallahassee, Fla.
Decarteret tied the school record in the pole vault with a winning performance of 4.06m (13'3.75), beating out 20 others for the title. The sophomore's vault matched Laura Chmielewski's mark set back almost seven years ago on May 8, 2004. Decarteret has continued to make upw
Cutting Through Soil
Students pretend they are agricultural engineers during the colonial period and design a miniature plow that cuts through a “field” of soil. They are introduced to the engineering design process and learn of several famous historical figures who contributed to plow design.
Raging Rivers
Student are introduced to rivers, and to the components of the water cycle. They think about the effects of communities, sidewalks and roads on the natural flow of rainwater. Students also learn about the role of engineering in community planning and protecting our natural resources.
