Links to other web sites are provided, and users may access more up-to-date El Nino stories by clicki
Manipula math with Java : inner center
This applet shows students that there is only one circle inside a triangle tangent to all three sides. Users can specify any triangle they wish; the triangle starts out with three small circles, one in each corner. Users move the circles' centers until the circles are tangent to all three sides, while the circles' radii expand depending on where they are moved. No matter where the three circles start out, they all end up in the same location, which is shown by letting users superimpose them. The

How Space Shuttles Work
This site explains the complexity of the entire mission of a space shuttle launch, orbit, activities, and return to Earth. Students and teachers can learn about the precise nature of space science including extensive preparations and examine the monumental technology behind Americas shuttle program, as well as the extraordinarily difficult mission it was designed to carry out. Information is also provided on the background and history of the space shuttle. Diagrams, full-color photos, highlighte
National Centre for Biotechnology Education Genetically Modified Food
Following the recent decision of Bayer CropScience to withdraw its herbicide-tolerant fodder maize, Chardon LL, the soonest we are likely to see commercial cultivation of any GM crop in the UK is 2008 . This mini-site examines the history of GM food in the UK. This content is appropriate for teachers or as an extension.
The science of light : funhouse mirrors background
This page briefly describes and illustrates the laws of reflection. It includes a short section on pedagogy and it relates the content to standards.
Identify rocks game
This is an interactive page where students identify 15 rocks.
Box model (grades 6-8)
This virtual manipulative enables the student to randomly generate data that is displayed on a chart. The chart shows the results of a simulated drawing with replacement from a set of numbers selected by the student. The manipulative can be used to simulate flipping a coin or tossing a die. A pause button stops the simulation. A button for showing theoretical probability places an outline on the theoretical probabilities chart, which allows the student to compare the theoretical and experimental
Quick take on the wide, wide world of geometry
As the social studies, art, and music classes in the middle school widen students horizons, some of your students may become fascinated with the art, costumes, and customs of other peoples in this and other times. The NCTM Principles and Standards calls for middle school students to be able to recognize and apply geometric ideas and relationships in areas outside the mathematics classroom, such as art, science, and everyday life.
Tides and gravity labs
How does gravity cause tides in the oceans? This section, part of an interactive laboratory series for grades 8-12, introduces students to four activities on tides and gravity that cover critical orbital speed between Earth and the moon, gravitational forces between two bodies, tidal effects from the sun and moon, and the change in tidal levels over time. The activities include hands-on animations of concepts whose variables can be manipulated by students. Questions posed to students include ans
Science Sampler : Rockin' around the rock cycle
The following inquiry-based activities were designed as part of a unit intended to aid students in understanding the rock cycle, with the assumption that, after being taught the lessons in the unit, students would have gone beyond a rote memorization of the rock types and rock cycle. The ultimate goal of this hands-on lesson is that students will know and be able to discriminate between them.
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
Our Solar System
This site contains information about the nine planets, the sun, and the moon. Included is each planet's size compared to the sun. Students can click on a picture to discover the following information: the diameter, mass, temperature, number of rings, what it's made of, can life exist there, and other interesting facts. Included for each planet are the number of moons, length of a day and year, and the average distance from the sun. Students can enter their weight to find out how much they would
Science Sampler : Thinking about students' questions
Asking questions is a vital component in any classroom, but it is absolutely essential in a science classroom. As science teachers, we know that questioning plays a major role in the inquiry process and has a positive impact on students' learning. This article discusses the importance of questioning skills and current research on questioning techniques. In addition, this article will present a series of lessons that were implemented by the author to improve the questioning abilities of middle sc
Indirect measurement and trigonometry
This online workshop session offers practical experience in the use of trigonometry. Teachers work together on examples of measuring impossible distances and inaccessible heights as they explore a number of methods for indirect measuring. They learn about right triangle trigonometry and use trig ratios to solve problems. This is one session from Measurement, a free online course developed for elementary and middle school teachers.
Statistics and probability. Grades 6-8
This MathPARTNERS unit contains seven lessons with hands-on learning activities for exploring statistics and probability with students in grades 6-8. The lessons, designed for mentoring situations, may also be helpful for teachers and parents. Each lesson with reproducible student materials, features an overview of the mathematics, preparation guidelines, teaching tips, and suggestions for how to use each activity to develop specific mathematics concepts. Statistics activities focus on posing qu
