Critical Evaluation of a Web Site : Middle School Level
This is a checklist designed to help middle school users critically evaluate web resources. By answering the questions in the checklist, students can then assess if the site would be a good one to use for their science research projects. There is a series of How does it look? questions and a series of What did you learn? questions that challenge students to think critically about what they are looking at and then summarize the effectiveness of the web site.
T.P. Away
What's a quick way to unroll a roll of toilet paper? This material is part of a series of hands-on science activities designed to arouse student interest. Here students use Bernoulli's principle and an electric leaf blower to force air over the top of the toilet paper to quickly unroll it. The activity includes a description, a list of science process skills and complex reasoning strategies being used, and a compilation of applicable K-12 national science education standards. Also provided are c
Science Sampler : Growth Potential
Students will enjoy carrying out this exciting and challenging research project that combines science with computers and mathematics to investigate how polyacrylate animals change in size over time when placed in water and aqueous salt solutions. The hands-on activity motivates students and provides them with enjoyable and rewarding science project experiences. Here they have an opportunity to solve a problem and use the science inquiry skills of observing, collecting, organizing, and analyzing
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.
A Sphere's Surface Area and Volume
What is the relation between a sphere's surface area and its volume? How does their ratio change?
Area of Parallelograms : Activity A
Examine and manipulate the graph of a parallelogram or triangle and find its area. Explore the relationship between the area of a parallelogram and the area of a rectangle using an animation.
This Planet Really Rocks
This ThinkQuest Junior site contains information and activities about rocks and minerals. Included is information about what a rock is, the major characteristics with examples of sedimentary, metamorphic, and igneous rocks, the rock cycle, the differences between rocks and minerals, how to identify minerals (color, luster, streak, cleavager, hardness, and specific gravity), and the Mohs Scale. Facts about common minerals and their properties, how rocks and minerals are important, and their uses
Fractal Musicand Fractal Music Lab
This first website offers a collection of fractal music using images created by G.W.F. Albrecht. The technology and mathematics which this presentation draws on is described on the second website. The second website, developed by David Strohbeen, offers some basic information about fractals and fractal music. He has also posted some samples of his music and invites visitors to download software for creating fractal music and to submit their own compositions.
Place Values
This site has explanatory lessons, interactive practice, and challenge games all dealing with place value. Includes information, practice, and games on place value of two, three, six and seven digit numbers and expandend notation for two, three, six, and seven digit numbers. Problems are randomly selected and students receive immediate feedback with the correct response. The bottom of each lesson page contains timed exercises.
The online geoboard
This applet simulates the use of an actual geoboard without the usual limitations of working with rubber bands. geoboards are used to investigate shapes, area, and perimeter. With this applet, students have choices about the number of pegs on the geoboard and the number of rubber bands. They also may select to have the area filled in within the shapes or merely work with rubber band outlines. Most materials designed for real geoboards may be used with this online version.

Will it Float?
Student preconceptions are one of the greatest challenges we face as science teachers. This Predict, Explain, Observe, and Explain (PEOE) activity challenges students' preconceived notions about why matter floats or sinks when placed in a liquid. The idea behind this model is to do a demonstration that first confirms students' conceptions followed by a second, similar demonstration that provides discrepant information creating cognitive dissonance. Learning happens as students are forced to modi
Energy in-depth timeline
The history of energy usage provides an interesting view of the development of technology over time. This informational piece, part of a series on the future of energy, introduces students to the advancement of technology through the use of energy. Students read how energy needs and uses have affected the production of power, manufacturing industries, and transportation methods. This piece focuses on energy systems based on fossil fuels, geothermal, hydrogen, nuclear, solar, and wind energy, and
Inside a Seed
This image from Biology by Kenneth R. Miller and Joseph Levine illustrates the five most important parts of a seed: the seed coat, the endosperm, and the embryos primary root, cotyledon, and embryonic leaves.
Earth and Space
In earth and space science, students study the origin, structure, and physical phenomena of the earth and the universe. Earth and space science studies include concepts in geology, meteorology, oceanography, and astronomy.
2.14 Summing up
This unit is concerned with macroevolution – 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.

By Land, Sea or Air
In this lesson, students learn that navigational techniques change when people travel to different places — land, sea, air and in space. For example, an explorer traveling by land uses different methods of navigation than a sailor or an astronaut.
6.4 Second Essay
Childcare, education, working conditions, healthcare, crime … these issues are hotly debated in today's society. They are also issues that Robert Owen, seen by some as a visionary and by others as a knave and a charlatan, sought to address in the early 1800s. This unit uses a series of essays written by Owen to explore the ideas of this important and controversial figure.
Engineering an Empire - Greece, Part 4/5
(NOTE: There is a Greek statue with male frontal nudity.)'The term ancient Greece refers to the period of Greek history lasting from the Greek Dark Ages ca. 1100 BC and the Dorian invasion, to 146 BC and the Roman conquest of Greece after the Battle of Corinth' (Ancient Greece, Wikipedia, 2009).
