Periodic Table Mystery By Chuck Roser, Retired Chemistry Instructor North Carolina School of Science and Mathematics National Science Education Standards Grades 9–12 Periodic Table of the Elements 1 Periodic Table of the Elements – Cylinder with Bulges The main purpose of any periodic table of the elements is to help us understand the relationships among the various elements. We want to construct a “periodic table” that is a reasonably faithful representation of the observed relationships. We shall see that there are many advantages to thinking of the periodic table as a three-dimensional object (rather than as a flat, two-dimensional object).

Advanced - Experiments - Practical Chemistry This website is for teachers of chemistry in schools and colleges. It is a collection of experiments that demonstrate a wide range of chemical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Chemistry is a practical science. 100 Incredible Lectures from the World’s Top Scientists Posted on Thursday June 18, 2009 by Staff Writers By Sarah Russel Unless you’re enrolled at one of the best online colleges or are an elite member of the science and engineering inner circle, you’re probably left out of most of the exciting research explored by the world’s greatest scientists. But thanks to the Internet and the generosity of many universities and online colleges, you’ve now got access to the cutting edge theories and projects that are changing the world in this list below.
Chapter 4: The Periodic Table & Bonding Skip Navigation Middle School Chemistry big ideas about the very small Lessons Materials Vist the materials page to see exactly which materials you'll need to complete the lessons in Chapter 4. 2002 Personal Account: Chemistry Lesson (2002, England) I am a high school science teacher in Birmingham. I usually teach physics, but due to teacher shortages, I ended up teaching chemistry a few years ago. As you all know, chemistry can be fun, especially when you get onto the subject of reactive metals. I decided to liven up a particular chemistry lesson by demonstrating the awesome energy released when silver nitrate, magnesium, and a drop of water are mixed. This particular reaction is very violent, exploding in a brilliant white flash when the water is added. It usually ends up shattering the crucible.

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.
Database of Periodic Tables There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach.
