Many U.S. towns are named after common Elements. Various Elements reside in abundance in the areas, so the towns earned the name. Many valleys or mine areas are named after the minerals found there. The abundance of U.S. towns named after Elements isn't the greatest, but it is a high number. The U.S. is home to very many elements and many towns have taken the elements into their name.

Evan, Make a connection to chemistry by giving a least one example! 4 stars. MW

The international standard for a Kilogram has been revised for accuracy and is a big deal in the science world. I thought it was interesting that the Kilogram needed to be renovated because it lost 50 nanograms. I never knew they had an exact SI for a kilogram and I had always thought the "Kilogram" had been found once and guessed ever since. The kilogram is made out of platinum-iridium, which I found very interesting because I had seen Pt on the Element Table and I had always wondered what was made of Platinum.

Evan, OK. Yes I wonder why it was made of Pt - I think because it is so unreactive. 5 stars. MW

Motion Detectors: I found this article interesting because of the explanation of the beams and rays motion detectors give off. It kind of made me think about the comparison between infared beams and Alpha/Beta/Gamma rays. I think its interesting how these work and that there is more than one way to set up one. The different frequencies of light and how they affected the electrons was interesting because I know that the electrons are in the Electron cloud, which is by the Nucleus. I thought it was interesting how light can affect the core of an atom. Last, the "photoelectric effect" was interesting because of how light can send an electric current. I found this very interesting and cool.

Evan, That photoelectric effect stuff is way cool and also won Einstein a Noble prize. 5 stars. MW
