In this lesson, students will learn that ice formations on land will cause a rise in sea level when they melt, whereas ice formations on water will not cause a rise in sea level when they melt. They will also learn that ice is less dense than water, that ice displaces water equal to the mass of the ice, and they will practice some of the steps involved in a science investigation.

Much of the more than 30 million tons of asbestos used in the United States since 1900 is still present as insulation in offices and schools, as vinyl-asbestos flooring in homes, and in other common products. This book presents a comprehensive evaluation of the relation of these fibers to specific diseases and the extent of non-occupational risks associated with them. It covers sources of asbestiform fibers, properties of the fibers, and carcinogenic and fibrogenic risks they pose. The book may be read online, printed, or purchased from the site.

This site features Java Applet, QuickTime, and Flash animations that illustrate characteristics and functions of the atmosphere. They show how atmospheric temperature, pressure, and density change with respect to changing altitude, the way different kinds of radiation (x-ray, ultraviolet, visible, and infrared) act in various levels of the atmosphere (troposphere, stratosphere, mesosphere, and thermosphere/ionosphere), how oxygen gas and chlorofluorocarbons (CFCs) interact with ultraviolet radiation to create and deplete ozone, and the manner in which radiation is trapped in the atmosphere, causing the greenhouse effect and global warming. The animations can be paused and rewound to stress important points. These resources are suitable for use in lectures, labs, or other teaching activities.
