Scope on Safety : Essential First Aid for Science Teachers
From a practical standpoint, science teachers should be trained to respond to incidents involving burns, bleeding, chemical exposure, swallowed poisons, penetrating objects, lacerations, and shock. Basic training is required to properly handle these situations, and this training should be reviewed annually. A list of possible lab incidents and the appropriate first-aid response is provided.

Fraction four
In this two-player online game, students combine math skills and strategies to practice simplifying, converting, and multiplying decimals, percentages, and fractions. For each correct answer, the player places a colored ball on a 10-by-10 grid. The first person to place four balls of his or her color together in a row or diagonally wins. Students can choose different difficulty levels, response time limits, and types of questions. Problems range from simple calculations for reducing fractions to

Seeing our world through a different light
The Cool Cosmos team has made its main occupation to communicate and explain the world of infrared astronomy to students and the public at large. We have created websites that explain Infrared Astronomy, its timeline, as well as the many benefits and uses of Infrared in the different aspects of our lives. We have created award-winning web activities where students perform a version of the experiment in which the famous astronomer Sir Frederick William Herschel discovered infrared light. We have

Coal mine safety : whose responsibility
This November 28, 2007 entry in the NSDL Expert Voices blog, Connecting News with National Science Education Standards deals with reported increases in coal mine accidents and insufficient government inspections and is related to NSES Personal and Social Perspectives and Science and Technology. Teachers can use this opportunity to discuss with students how politics impacts science, the role consumer demand for coal might play, and what mining engineers do.

A Natural Fusion: Math and Science Across the Curriculum : Northwest Teacher, volume 4 number 1
Articles in this issue of Northwest Teacher focus on integrating math and science across the curriculum. Teachers create learning experiences for students, of all grade levels, that transcend the power of any one of them taught in isolation. With todays national spotlight on improving students reading and math skills, the potential for cross-disciplinary teaching of these subjects may be readily apparent. But science, too often nudged to the hinterlands of the curriculum when state standards and

Who Was Charles Darwin?
In this lesson, students will learn firsthand, by reading his journal entries and letters, how Darwin arrived at his theory. They also will gain a better sense of Darwin's journey and the role it played in his scientific career. In the first activity, Darwin's Great Voyage of Discovery, students will read his account of his voyage on the Beagle and see how this experience inspired him to devote the rest of his life to developing and refining the theory of natural selection. The second activity,

This workshop session, part of a free online course developed for elementary and middle school teachers, explores the mean in depth. Participants work together to investigate the mean as the balancing point of a data set and come to understand how to measure variation from the mean. Video segments, interactive practice, problem sets, and discussion questions involve participants in active exploration.

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.

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

How does ozone in the upper atmosphere help protect life on Earth? This informational piece, part of an interactive laboratory series for grades 8-12, explores the production and destruction of ozone in the upper atmosphere. Here students view an animation of ultraviolet light breaking an oxygen molecule to form ozone and then the ozone splitting when struck by ultraviolet light. Text explanations are provided along with chemical equations. Copyright 2005 Eisenhower National Clearinghouse

Science Sampler : The sweet Earth
A great number of geologic processes either take unimaginable lengths of time to complete, or happen in places that cannot be directly observed, such as under the Earth's crust. It is, therefore, necessary for an Earth science teacher to find a connection between students' experiences and the geologic process they are studying to help them better understand that which is often unobservable. One Earth science topic with a tendency to be beyond the reach of direct observation for students is rock

Density Balloon
What happens to the density of a balloon as it is heated and cooled? This material is part of a series of hands-on science activities designed to arouse student interest. Here students use a hair dryer to heat a helium-filled Mylar balloon, causing it to rise, and let it cool, causing it to drop. 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.
