Periodic Table Mystery By Chuck Roser, Retired Chemistry Instructor North Carolina School of Science and Mathematics National Science Education Standards Grades 9–12 (HU2—Evidence and Models, HB2—Structure and Properties of Matter) Objective Using coded symbols for the main group elements in the first 4 periods of the periodic table, students will generate a periodic table from pertinent clues. Introduction The periodic table used today is a product of the 1st periodic table published by Russian chemist Dmitri Mendeleev in l869. Each known element possesses a complete set of properties that fully characterizes it and distinguishes it from all other elements. Pre-activity questions List 4 properties that distinguish metals from nonmetals. Procedure Place the unknown main group elements on the blank periodic table using the clues provided. Clues Post-activity questions Is L a metal, nonmetal, or metalloid? Pre-activity answers Metals have metallic luster (shine) and nonmetals do not. Post-activity answers L is a metal.

INICIO | Paleourbana Digging for Rare Earths: The Mines Where iPhones Are Born MOUNTAIN PASS, Calif. -- About 60 miles southwest of Las Vegas, in a mine some 500 feet deep, the beginnings of an iPhone come to life. But the sleek, shiny iPhone is far, far removed from the rocks pulled out of this giant hole, which looks like a deep crater on the moon. A very deep crater. The ground is covered with rust-colored boulders, rocks, and pebbles. The base of the mine is several football fields wide. Inside the rocks from this mine are rare-earth minerals, crucial ingredients for iPhones, as well as wind turbines, hybrid cars, and night-vision goggles. "Your iPhone doesn't work without rare earths in there, " said Mark Smith, chief executive of Molycorp. What's unique about Molycorp is that it's trying to harvest rare-earth minerals in an environmentally friendly way, or at least as environmentally friendly a way as a mine can manage. "We started working at trying to do things differently," Smith said during a tour of the mine. "The lake instantly assaults your senses.
Ten Websites for Science Teachers We all know that the web is full of excellent web resources for science teachers and students. However, unless you live on the web, finding the best websites can become quite a challenge. This isn't a "Top Ten" list -- instead, it is a list of websites that I either use on a regular basis or just find interesting. From teaching resources for the nature of science and authentic field journals to wacky videos about numbers, I am sure that you will find something in the following list the works for you! 1) Understanding Science UC Berkeley's Understanding Science website is a "must use" for all science teachers. 2) Field Research Journals The Field Book Project from the National Museum of Natural History and the Smithsonian Institution Archives intends to create a "one stop" archive for field research journals and other documentation. 3) Evolution Berkeley's Understanding Evolution website is the precursor to their Understanding Science efforts. 4) PhET Simulations 5) Earth Exploration
