This past month was the Tucson Gem & Mineral Show. This year’s theme was “The Minerals of the Mid West.” The show displayed many beautiful gems and minerals including geodes, calcites, turquoise, fluorite, wulfenite, and more. You haven’t herd of wulfenite? Nether had I until I found out that there Is a house bill to make wulfenite the state mineral of Arizona. If the bill passes Arizona school children will all know what wulfenite is.

Dr. Hank Hurrass visited Ridgeline Academy to teach summer school students about the Hellcat coil that just became a part of the Guinness Book of World Records. We learned that it took him a year to build the Hellcat coil, and he didn't know whether it would even work. The coil is not a new invention, in fact, it has been around for over a century, one of the many novel creations of inventor and electrical engineer Nikola Tesla, who also developed radio and radar waves, fluorescent lights and the AC distribution system used in our homes today. 

There is an amazing camp in Tucson for girls going into 5th, 6th, and
7th grades. It is called the Colors of Nature Academy, and it teaches
girls science through art. The camp is organized by researchers from the University of Alaska Fairbanks, the National Optical Astronomy Observatory in Tucson, and the University of Washington Bothell. The camp lasts two weeks and is actually a study funded by the National Science Foundation. The Colors of Nature Academy is held at the University of Arizona campus. There is no cost to attend the camp, but girls must apply.
