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

Your sense of taste
This brief illustrated resource about the sense of taste is part of a feature that explores how humans experience flavor. The five taste qualities--including umami--are mentioned. The resource also corrects the misconception that humans can only taste certain food qualities at specific regions of the tongue. A set of connected, labeled diagrams of the tongue, taste buds, the brain, and facts about taste are noted in a sidebar. One fact compares the average number of taste buds in humans, chicken
Mineralogy 4 Kids Rockin Internet Site
The Mineralogical Society of America's Mineralogy 4 Kids Rockin Internet Site is described as "The BEST Place to Learn about Rocks and Minerals." Subjects include Minerals in Your House, Mineral Groups and Properties, Mineral Games, and All About Crystals. Another activity is entitled Rock Cycle, which offers a well done graphic and description of how rocks are transformed into the three major families: igneous, sedimentary, and metamorphic. The additional links that are provided throughout the
systems of linear equations
Solve a system of linear equations by graphing and finding the intersection of the lines of the equations. Create a system of equations, examine its graph, matrix, and table of values, and determine the solution of the system.
Who Gets the Job?
Each job candidate can see the other two candidates' black or red dots but not his own. Whoever can figure out the color of his own dot gets the job.
In this lesson, students model a bungee jump for a Barbie doll. They collect data in a table (number of rubber bands and jump distance), then create a scatterplot of the data, find its line of best fit, and write an equation of that line. Students go on to analyze the equation, noting its slope in relation to the data collected, and the meaning of the y-intercept. Since the distance to which the doll will fall is directly proportional to the number of rubber bands, the lesson provides a scenario
Science Sampler : The scientific method -- Is it still useful?
Many scientists and science educators contend that a structured scientific method does not exist, while others might argue that the scientific method is too simplistic in its approach to scientific inquiry. This article addresses the dilemmas surrounding the scientific method, and provides suggestions that will enable you to ?meld the method with process skills.?
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
The Science of Sound
This site contains a series of experiments about sound and its application to animals, musical instruments, and communications. Designed for second graders, each half hour experiment gives the students the introduction, a list of needed materials, and the procedures. Students can easily work in pairs with minimum adult supervision. Included are Animal Challenges which are activities that encourage kids to apply the concepts of sound to the animal kingdom.
Caesar Cipher II
users practice simple arithmetic skills by encoding and decoding messages to determine the form for an affine cipher.
Issue in-depth : Inside alternatively powered vehicles: The problems and the possibilities
Like all things natural or human-made, all modes of transportation, from horses to spacecraft are governed by the Principle of conservation of matter, the First law of thermodynamics, and the Second law of thermodynamics. The activities described in this article help students to explore the varied methods for powering our transportation needs, and provides students with valuable knowledge and practical experience in applying these scientific laws and principles that govern matter and energy in u
Meter : Metre
This article gives detailed scientific information related to the creation of the meter. The material connects the scientific theory behind the metric system to the practical efforts of Mechain and Delambre, including the historical times in which they worked. Information includes further definition of the meter, first as a bar and then as a specific distance measured by light.
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.
Platonic solids, duals (grades 6-8)
Using this virtual manipulative, the student can examine the dual relationship among the five platonic solids, each a polyhedron with identical regular polygonal faces. Every platonic solid has a unique platonic solid that fits inside it, with its vertices at the midpoints of the original solid. The student can manipulate, color, and change the size of each solid. A transparent mode is available for viewing the outline of each polyhedron and its dual. Instructions for using the applet and inform
TOPEX/Poseidon - Overview
This resource presents basic information about how the TOPEX/Poseidon satellite works, what factors affect ocean topography and how ocean circulation affects the Earths climate. Remote imagery, diagrams, and links to related topics are included.
This activity generates a stem and leaf plot from data that the user enters.
Frequently Asked Questions: Questions About Paleontology
This site asks and answers questions about paleontology, fossils and dinosaurs. Paleontology questions are: What is paleontology? How does paleontology differ from anthropology and archaeology? What are the practical uses of paleontology? How do paleontologists know how old their fossils are? What training is necessary to become a paleontologist? What organizations exist for paleontologists?
Examine rocks from a satellite view and zoom in to a microscopic view
Created for high school students, this interactive Earth science visualization shows rocks at nine different scales, from a photograph of the Earth taken aboard Apollo 17, to an image of atoms created with an electron microscope. The site also provides views of continents, mountain ranges, rock formations, and minerals within a rock. The resource points out that by studying rocks at different scales, geologists can learn about Earth processes. Students are able to click on icons such as a satell
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
