This Web site contains a pictorial guide to insect mouthparts, a complicated topic served well by this simple yet effective tutorial. Created by University of Ottawa entomology professor Dr. Houseman -- using material adapted from Digital Zoology (on CD from McGraw-Hill) -- this site provides labeled diagrams and high quality photos of chewing, siphoning, piercing, sponging, and combination mouthparts. Users may view images by category or click through the entire set in sequence. The photographs
The National Academy of Forensic Engineers (1) provides a short definition of forensic engineering as: "the application of the art and science of engineering in matters which are in, or may possibly relate to the jurisprudence system, inclusive of alternative dispute resolution." Specialty areas in forensic engineering include fire investigation, industrial accidents, product liability, traffic accidents, civil engineering and transportation disasters, and environmental systems failures. For exa
Climate of 2002 Preliminary Annual Review
The National Climatic Data Center of the National Oceanic and Atmospheric Administration (NOAA) has made available the Climate of 2002 Preliminary Annual Review Web site. Visitors will find numerous charts; graphs; tables; and descriptions of global temperatures, temperature trends, regional temperatures, and global precipitation. A US climate summary, as well as information on significant events, the Atlantic hurricane season, and the western US wildfire season, is also available. The site has
NSTA Webwatchers' Science Guides
The Webwatchers' Science Guides website -- provided by the National Science Teachers Association -- is a portal to educational resources on the Internet. Along with carefully selected links, this website offers a few downloadable lesson plans, as well as audio reviews from fellow teachers and vignettes demonstrating how to use the Guides in the classroom. Navigation can be somewhat tricky -- the site follows an elaborate organizational scheme that requires its own 4-page explanation. For a quick
World Weather Information Service
The World Meteorological Organization Web site offers the World Weather Information Service page. Here, visitors will find official weather forecasts and climatological information for selected cities worldwide. Users choose a particular continent and country, and are then presented with a list of various cities they can get information on. This includes the date and time of the current forecast, minimum and maximum temperatures for that day, a general cloud description, and a monthly review of
Using technology to support Limited-English-Proficient (LEP) students' learning experiences
This article examines the challenges and rewards related to using technology as a tool to increase learning for limited English-proficient (LEP) students. The article is based on the belief that students' content, linguistic, and technology skills should be developed in tandem. Strategies and standards for technology use are featured along with suggestions for enhancing LEP students comfort level in content classes. Access and equity and the redefinition of teacher roles are also discussed. Impr
Ready to Teach (RTT) interactives library
This web site offers access to four interactive software tools designed to help teachers and students of algebra visualize and experiment online with key concepts related to linear and piecewise functions. Copyright 2005 Eisenhower National Clearinghouse
How high? : measurement (grades 6-8)
With this virtual manipulative, the student investigates conservation of volume with a virtual simulation of pouring a liquid from one container to a container of the same shape, but of a different size. There are four cylinder shapes to choose from: rectangular prism, cylinder, cone, and pyramid. The left container is partially filled with liquid and the base dimensions of the two cylinders are given. The student uses a slider to estimate how high the liquid will rise when poured into the secon
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
Cynthia Lanius' Fractal Unit
Cynthia Lanius, a former mathematics teacher who currently serves as Technology Integration Specialist for Sinton Independent School District in Sinton, Texas, has posted numerous lessons online. This website features a Fractals Unit for elementary and middle school students (although adults are also welcome to enjoy the lesson). The lesson includes a discussion on why one might study fractals and then provides step-by-step explanations on how to make fractals using Java, along with some challen
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.
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.
Andes Mummies: Chachapoya Tombs
This 3:44 minute video shows the history of the Chacahpoyas, their culture, architecture, and influences on the surrounding neighbors and about how they revered their dead and the tombs they built. A good video to gain insights into where they lived and how they lived.
Learn about The Geology of the Earth
This 4:42 video provides a quick overview of the geology of the Earth with good graphics. It would be best to include a handout of terms, such as plates, to help the students. Shows how earthquakes occur as well as other events such as volcanic action.
3.1 Introduction to improving own learning and performance This key skill is about helping you understand how you learn; think about how you can improve your own learning and performance, and consider how you might generalise the principles and processes for future learning. You saw in our discussion of ‘A framework for learning’, improving your learning and performance could be considered to be a ‘meta-skill’, that is the skill of learning how to learn. This section, then, is a little different from the other skills sections

5.2 Other transmission media
BBC News 24, Sky News, CNN – we live in an era where news has become almost instantaneous. This unit will look at how news is gathered and the technology used for its dissemination. You will also be encouraged to examine how information might be manipulated by questioning its reliability.
Maximum Ozone Hole Area for 2000
This still shows the maximum stratospheric ozone hole over the Antarctic for 2000.
A female chicken is called a hen. A hen is capable of laying eggs. She has feathers to let her fly, a tail for balance, and the comb and wattle both help cool the hen off by circulating blood through them.
MRI Safety Grand Challenge
This module was written for a first year accelerated or AP physics class. It is intended to provide hands on activities to teach end of the year electricity and magnetism topics including the magnetic force, magnetic moments and torque, the Biot-Savart law, Ampere's Law, and Faraday's Law. During the module, students utilize these scientific concepts to solve the following problem: A nearby hospital has just installed a new Magnetic Resonance Imaging facility, which has the capacity to make a th
