Allies and Aliens

Rating
0.0 stars

In the learning module Allies and Aliens students assume the role of agents from planet Earth who must assess varying degrees of prejudice and misinformation as they visit Web sites from other planets. Because most kids don't think to look for bias or false information online and subtle forms of racism may be difficult to recognize, Allies and Aliens uses the pretense of an evaluation mission to keep players from guessing its true purpose right away. The mission is divided into two parts. On Day One, students encounter information with little direction. On Day Two, the module's purpose becomes apparent. Allies and Aliens aims to teach students the basics about bias, stereotyping, misinformation and propaganda techniques, on the Internet and in other media. It also helps students to understand the difference between fact and opinion, and the importance of authenticating online information. The challenges of this module will ultimately sharpen students' research skills as well as their critical thinking skills. The experience will teach them to recognize viewpoint, bias, and manipulation -- online and off.

Asbestiform Fibers: Non-occupational Health Risks

Asbestiform Fibers: Non-occupational Health Risks

Rating
0.0 stars

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.

Atmosphere Animations

Rating
0.0 stars

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.
