A Net Meltdown is Inevitable
On October 22, 2002, an attack on the thirteen servers that act as the backbone of the Internet was carried out, briefly disabling nine of them. This drew attention to the often criticized organization that operates these servers, the Internet Corporation for Assigned Names and Numbers (ICANN). This news article argues that bad practices and insufficient safety precautions of ICANN may soon lead to a more successful attack, one that could cripple the Net. It also stresses the importance of refor

Brainpop describes itself as the leading producer of educational animated movies. Their Web site has a science page that currently contains sixty-five animated movies, with a large portion of them being physical science related. Each subject contains a 3-4 minute Movie, an Interactive Quiz, an Experiment, a Comic Strip, a How-to hands-on application, a Timeline, and a printable Activity Page. Visitors can play three movies per day for free (all of which begin by a somewhat annoying ad for subscr
What is Design?
Children between the ages of nine and twelve will be drawn into this site that explores the world of design. It encourages "kids to develop critical viewing, technical mastery, artistic awareness, and practical, just, solutions." Many interactive games and activities are available, allowing users to create their own designs and share them with others. For example, children can design their own watch with a simple step-by-step process, and many watches are featured in a gallery. A wealth of infor
This website contains the techniques, tips, and secrets used by master teachers of mathematics. Based on research, the authors argue that rote memory is one of the least effective ways of memorizing. They offer more effective strategies for teaching students the times tables and some strategies for helping with memorization, such as using rhyming words, pictures, stories and other activities. Much of the material here is drawn from a book called Memorize in Minutes: The Times Table, which is ava
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.
The Nitrogen Cycle : Of Microbes and Men
This module provides an overview of the nitrogen cycle and the chemical changes that govern the cycle. It includes explanations of how nitrogen is used by organisms and how humans effect the cycle.
Fractions with Unlike Denominators
Find the sum or difference of two fractions with unlike denominators using graphic models. Find the least common denominator graphically.
PBS provides students in grades 4-7 with oodles of science fair ideas and a science fair tip sheet in this section of the DragonflyTV web site. Overviews of investigations from the television show are offered to help students hone in on an interesting topic and create their own science fair project. Each overview relays a question that a child asked on television, the main steps in his or her experiment, and the results. The overviews also include ideas for further investigations that build on t

Building Roller Coasters
Students build their own roller coasters using pipe insulation and marbles, and then analyze them using principles of physics. They examine conversions between kinetic and potential energy and frictional effects to design roller coasters that are completely driven by gravity. A class competition is then held to determine the most innovative and successful roller coasters.
Students use the engineering design process to solve a real-world problem — shoe engineering! Working in small teams, students design, build and test a pair of wearable platform or high-heeled shoes, taking into consideration the stress and strain forces that it will encounter from the shoe wearer. They conclude the activity with a “walk-off” to test their shoe designs and discuss the design process.
