An Introduction to the Coordinate Plane
This math site has students find points on a number line and graph points in the coordinate plane. Site includes information about negative numbers on a line, changing the scale of a graph, estimating points, and tricky graphs. A glossary of terms, links to other sites, and suggestions on how to use the material can also be found.

Watersheds
This web page focuses on watersheds, the topic of one of the books in the curriculum series that the larger web site accompanies. The page mentions why it can be beneficial for students to investigate local watersheds. The term watershed is defined, and examples of different sizes of watersheds are given. In addition, the page explains why local governments often manage watersheds. Links are provided to water quality experiments, to related online materials on other sites, and to information abo

Light and optics
It doesn t take Superman s special strength to take light and bend it, bounce it, or divide it. Teachers and students can read this series of brief articles to learn how the properties of light allow these optical wonders to happen in everyday life. You can navigate through the sections of the module by clicking on objective statements or connect to additional readings or activities through links at the bottom of the pages. Each article has photographs that represent the objective. For example,

Student time on task is the most influential factor in student achievement. To maximize time on task, teachers need to make decisions about the systems they install in their classroom well before any students enter the room. Beginning the school year by explicitly teaching process skills and having classroom operating systems that reinforce process skills are two strategies that lay the foundation for logical thinking throughout the year, which are discussed in this article.

Space blocks : algebra (grades 6-8)
This virtual manipulative offers the student an opportunity to develop spatial sense and the ability to model ideas using mathematics. In seven activities, the student models shapes with cubes and observes patterns related to surface area of a solid. Activities involve forming largest and smallest solids using eight blocks and determining which of three networks of squares decorated with colors and shapes can be folded to form a given cube. This manipulative provides two user controls. The stude

Algebra balance scales : negatives (grades 6-8)
This online manipulative features a virtual balance scale. It offers students an experimental way to learn about solving linear equations involving negative numbers. The applet presents an equation for the student to illustrate by balancing the scale using blue blocks for positive units and variables and red balloons for negative units and variables. The student then works with the arithmetic operations to solve the equation. A record of the steps taken by the student is shown on the screen and

Activity : Fusion Reactions
This activity gives students an opportunity to learn about the elements created in the cores of high-mass stars by fusion reactions. They will discover that all stars start by burning hydrogen and end up creating many heavier elements inside their cores, elements that will be released into space when it dies in a supernova explosion. Students associate a layer with an element that is being produced by the high-mass star. This will illustrate that as the temperature of the star increases with dep

Soil Litter: The Food Web
Teachers could incorporate this brief radio program into a variety of learning settings. For example, teachers living in the temperate deciduous forest biome can play the program for students when leaves begin to fall in autumn. The program could also be used whenever students anywhere are learning about food webs or soil. Teachers can choose to use either the audio or text version (or both) to give students listening or reading practice.

The MegaPenny Project
This site illustrates the magnitude of large numbers by showing and describing arrangements of large quantities of U.S. pennies. It begins with16 pennies that measure one inch when stacked and one foot when placed in a row. The next visual shows a thousand pennies, and in progressive steps the site builds to a quintillion pennies. All pages have tables at the bottom listing the value of the pennies on the page, size of the pile, weight, and area (if laid flat).

NPR
This article and audio file from National Public Radio highlights the work of Manjul Bhargava, a professor at Princeton University. He is an expert in number theory and a master of the tabla, a small Indian hand drum used to create music with rhythmic, precise patterns. In this article, Bhargava describes the mathematical and improvisational aspects of classical Indian music. The article is part of a Morning Edition series exploring the intersection of art and science. An audio file lets visitor

2.1 Introduction
This unit is concerned with macroevolution â€“ the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.

Learn to Build a Rocket in 5 Days or Your Money Back
In this lesson, students discover the entire process that goes into designing a rocket for any customer. In prior lessons, students learned how rockets work, but now they learn what real-world decisions engineers have to make when designing and building a rocket. They learn about important factors such as supplies, ethics, deadlines and budgets. Also, students learn about the Engineering process, and recognize that the first design is almost never the final design. Re-Engineering is a critical s
