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.

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

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.

Science Sampler : Differentiated assessment
One of the goals of science education is to encourage students to think and reason at increasingly higher levels. In order to accomplish this goal, the authors created a unique form of assessment that not only encourages students to work at the highest critical-thinking level possible, but also allows them creative liberty to express their understandings of the big ideas. This enables all students, including English language learners and special education students, to achieve their potential thr

Teacher's Toolkit : Reforming cookbook labs
The majority of ancillary materials provided with any textbook includes a large quantity of labs that have step-by-step instructions. Although it is important in science for students to learn how to follow directions, offering only cookbook labs limits students' access to exploration. Presented in this article are 11 different ways of altering cookbook labs so that students understand the intention of the procedure. The altered labs do not fully achieve the status of inquiry-lab, but they are a

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

Maximize Student Time On Task
Student time on task is the most influential factor in student achievement. To maximize time on task, teachers need to make decisions about the systems they install in their classroom well before any students enter the room. Beginning the school year by explicitly teaching process skills and having classroom operating systems that reinforce process skills are two strategies that lay the foundation for logical thinking throughout the year, which are discussed in this article.
