Sunlight and the Earth : Climate and Weather
These web pages trace the processes involved in the suns impact on weather. This is an exploration of the importance of radiation and reflection of light, both visible and infra-red, and the greenhouse effect. Convection and the role of water vapor are also considered. Global-scale air flows are described, explaining why wind in the continental US usually blows from the west, while near the equator it comes from the east.
Waves and Wave Motion : Describing Waves
This module introduces the history of wave theories, basic descriptions of waves and wave motion, and the concepts of wave speed and frequency.
Project Atmosphere Canada: Teacher's Guide
This teacher's guide from Project Atmosphere Canada is designed to promote an interest in meteorology among young people, and to encourage and foster the teaching of the atmospheric sciences and related topics in Canada. Topics include weather hazards such as hurricanes and thunderstorms; the use of radar and satellites in weather prediction; weather phenomena such as El Nino, wind patterns, high and low pressure, and clouds; sunlight, water vapor, and the upper atmopshere; and others. Each modu
Histogram (grades 6-8)
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
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
Star life cycle
This instructional tutorial, part of an interactive laboratory series for grades 8-12, introduces students to the life cycle of stars. The tutorial's introduction compares human life stages with those of stars, and it describes the makeup of space. In the following sections, students investigate protostars, the equilibrium process of stars, what constitutes a star, and what happens in the late life of a star when the helium and carbon present in it start to be consumed. Photographs and diagrams
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
Static Charged Two by Fours
How can you move a wooden two-by-four without touching it? This material is part of a series of hands-on science activities designed to arouse student interest. Here students use static electricity to attract and move a wooden two-by-four. 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 content topics, a list of necessary supplies, instru
The resources found on this web site can be used by individual teachers or teacher groups interested in expanding their use of assessment tools designed to inform teaching practice. Teachers will find the assessments and the supporting materials valuable additions to any professional development focused on assessment.
Graphing for Area
Middle School, difficulty level 2. Graph six points and find the area of the resulting hexagon.
When did the Grand Canyon begin to form?
This March 14, 2008 entry in the NSDL Expert Voices blog Connecting News with National Science Education Standards deals with the recent finding suggesting the Grand Canyon is two to three times older than commonly believed. Additional links to teaching resources related to earth systems structure, rock dating and the nature of science are provided.
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
Ohio resource center for mathematics, science, and reading
ORC provides links to peer-reviewed instructional resources that have been identified by a panel of Ohio educators as exemplifying best or promising practice. Available resources also include content and professional resources as well as assessment and general education resources that will support the work of preK to 12 classroom teachers and higher education faculty members. The resources are correlated with Ohio's academic content standards and with applicable national content standards.

New York Times Daily Lesson Plan: Mathematics
These lesson ideas from the New York Times offer suggestions for ways to draw on real world issues and statistics to develop lessons in mathematics. For example, in one lesson students convert statistics about gun injuries into visual presentations, then use these as the basis for a poster campaign to teach children about the dangers of guns in home while another lesson idea involves designing brochures that are intended to explain specific mathematical concepts to a popular audience.
