A Merry-Go-Round for Dirty Air
Students observe and discuss a cup and pencil model of a cyclone to better understand the science behind how this pollutant recovery method functions in cleaning industrial air pollution.
History and Mathematics: Magic Squares and Stars
In this activity, students research the history and legend of the Chinese mathematical puzzle known as the Magic Square, and explore various methods for reconstructing magic squares. Students will use number sense and arithmetic facts to find missing numbers in a magicsquare and/or magic star, and follow the directions given in words and diagrams to create a magic square of odd order.
Earth on Edge : Ecosystems
This site provides information about the six ecosystems on which life on Earth most heavily depends: agricultural, forest, freshwater, grassland, coastal, and urban. It is part of a Public Broadcasting System (PBS) project, which includes a discussion guide. Ecosystems are described as communities of interacting organisms and the physical environment in which they live.

Quick take on Pythagoras and his theorem
A topic once reserved for high school geometry, the Pythagorean theorem is now part and parcel of the middle school curriculum. These resources offer visual demonstrations that can make the abstract theorem more concrete for students and lead them in analyzing the mathematical relationships involved, as recommended by the Principles and Standards for School Mathematics. The last resource offers background information on Pythagoras himself.
Lines of best fit using least squares
Fit a line to the data in a scatter plot using your own judgment. Then compare the least squares line of best fit.
Indicators of Middle School Implementation: How Do Kentucky's Schools to Watch Measure Up?
Using responses of school personnel to a statewide survey, this study examined the perceived level of implementation of key tenets of the middle school concept as outlined by This We Believe: Successful Schools for Young Adolescents (National Middle School Association, 2003) in schools designated a Kentucky School to Watch as compared to nondesignated schools.,Volume 32, Number 6
Literacy for Middle School Students: Challenges of Cultural Synthesis
What does research suggest for middle level readers? Stronger attention to the literacy learning of middle level students and a greater degree of interplay between researcher and practitioner agendas.,Volume 28, Number 1
Difference of Squares
This lesson uses a series of related arithmetic experiences to prompt students to generalize into more abstract ideas. In particular, students explore arithmetic statements leading to a result that is the factoring pattern for the difference of two squares. An excellent teaching idea on how to help students walk the bridge from arithmetic to algebra.

Science Bulletins: On the Hunt for a Balanced Diet
Biologists had long assumed that predators were more concerned with the quantity of their food than the quality, but a recent study shows that nutritional value dictates how predatory ground beetles choose their prey. An international team of scientists led by University of Exeter and Oxford researchers collected more than 500 ground beetles in Denmark. One group of beetles was allowed to select from food sources with varying amounts of fat and protein, while the other group was given a fixed di
