Nebraska Earth Science Education Network
The Nebraska Earth Science Education Network has as one of its objectives to promote and enhance K-12 earth science education. The Web site provides lesson plans on various subjects including astronomy, geology, mapping, soils, water, and weather. Each submitted lesson gives a recommended grade level and contains objectives, materials needed, procedures, and conclusions, depending on the activity. The site is a great resource that provides unique and original information from teachers for teache
Popular Science: Best of What's New, 2003
Each year Popular Science selects new and emerging technologies that have profound implications in several different categories. The Best of What's New for 2003 explores innovations in aviation and space, computing, home technology, and engineering. A particularly interesting item is the SpaceShipOne rocket plane, which is one of the leading contenders to successfully demonstrate a cheap, reliable method of escaping Earth's atmosphere. Another featured technology is the newest standard for wirel
Mike's Electric Stuff
Mike's Electric Stuff is a popular Web site with various odds and ends about electronics and related equipment. Ever wondered just how much fun microwaving a CD can be? That's just the beginning of the wild things you can find. The site is divided into three main sections: antique glass (e.g., nixie tubes and neon lamps), Tesla coils and high-voltage stuff, and miscellaneous items such as lasers. Detailed instructions are given for several projects (perhaps crazy experiments would be the better
Climate Information Digest
The Columbia University's International Research Institute for Climate Prediction Web site (last mentioned in the October 27, 1999 Scout Report for Science & Engineering) offers a monthly publication called the Climate Information Digest, which is described as "a global quick look at seasonal climate, its impacts and outlooks."
