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,

Variation about the mean
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 ozone is made
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.

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.

El Nino vs. La Nina
This site offers images and animations showing global sea surface temperature (SST) and sea surface height (SSH) during El Nino of 1997-1998 and La Nina of 1998-1999. Images show the difference between the normal SST for that time of year and the actual temperature, clearly showing the higher and lower Pacific temperatures associated with the El Nino and La Nina events of 1997-1999 respectively. Thus the annual cycle and climatology have been removed from the data. Animations use Pathfinder and

The future of energy, efficiency
Energy-efficient appliances and vehicles can greatly reduce the amount of energy Americans use. This informational piece, part of a series about the future of energy, introduces students to the consequences of using energy more efficiently. An example about baking a pie provides students with a practical definition of efficiency. A discussion of energy-efficient appliances and processes follows as students read about the Energy Star label. The overall efficiency of a power plant is described, sh

Observe an animation of volcanism at a subduction zone
This Earth science resource features an animation of the volcanic activity that occurs when an oceanic plate subducts under a continental plate. An introductory paragraph provides background information about the events depicted in the animation. These events include the creation and eruption of magma and the formation of volcanic mountains at a subduction zone. Key features such as the asthenosphere are labeled at the beginning of the animation, and arrows indicate the direction of the oceanic
