This virtual manipulative enables the student to construct histograms to summarize data. A histogram divides the range of values in a data set into intervals. Each interval is shown as a rectangle whose area represents the percentage of data values in the interval. Students enter data into a table and the manipulative displays histogram and notes minimum and maximum data values, median and average, number in the data set, and standard deviation. The interval width is adjustable and displayed. Fe

Gravity Gets You Down
This site has students understanding that: 1) Without air resistance, all objects would fall at the same acceleration, regardless of mass. 2) Gravity is the force that causes objects to fall. 3) Air resistance, a type of friction, works against gravity to decrease the acceleration of a falling object. Included in this two day lesson plan are the objectives, needed materials, procedures, adaptations for older students, discussion questions, a rubric for assessment, extension activities, suggested

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.

Quick take on safety in the science classroom
With the increasing emphasis on hands-on instruction, it becomes more important than ever before for science teachers to be knowledgeable about laboratory safety issues. The National Science Education Standards say that students should have frequent opportunities to use a wide range of equipment, materials, supplies, and other resources for experimentation and direct investigation of phenomena. The National Science Teachers Association recommends that a minimum of 80 percent of science instructi

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.

Grapher : number and operations (grades 6-8)
Using this online manipulative, students can graph one to three functions in the same window, trace the function paths to see coordinates, and zoom in on a region of the graph. Function parameters can be varied as can the domain and range of the display. Tabs allow the student to incorporate fractions, powers, and roots into their functions. Instructions for using the manipulative and a link to the National Council of Teachers of Mathematics (NCTM) standard for number and operations are included

History of flight to reality, advanced text
This website is an on-line textbook on the principles of aeronautics. The major focus is to examine the history of flight to current events and trends in aeronautics. Initially the reader will be introduced to principles of lift, thrust, and control. Further topics of discussion will cover the first jumpers, the first balloonists, the historical people and study of gliders, powered flight based on the Wright brother's experience, the age of flight, early space flight, the U.S. space program, the

Observe solar eclipses
This Earth science animation helps students compare three types of solar eclipses: total, partial, and annular. The introduction explains how the type of eclipse is determined by variations in distance and alignment between the Earth, sun, and moon. The animation follows the events of all three eclipses concurrently. Movie controls allow students to repeat, pause, or step through the animation, which can give students more time to compare the eclipse sequences. Copyright 2005 Eisenhower National

Cold Clouds and Water in Space
This article from Astrobiology Magazine reports on the discovery of water in cold regions of space. Using data from the European Space Agencys Infrared Space Observatory, astronomers have determined that water is abundant in these cold, or quiescent regions of space where there are no stars, and that the majority of it occurs as ice with a small amount of water vapor. It is thought that these cold regions of space might be the future birthplaces of low-mass stars like our own sun. Links to other
