Four Articles on Observing and Teaching about Comets, especially November-January's Comet ISON (and two others!)
Comet CSI-Was That Comet a Murderer? - Astronomer Amy Lovell sets the scene: can comet gasses kill humans and life on Earth? Treating astronomy as crime investigation, she leads us to solving this Who-Done-It, learning the poisonous perpetrator's composition, vital statistics, finding its trail and clues to solve the mystery and declare a verdict! Teachers, turn your students into Comet Science Investigators with these activities.
The Insider's Tour of a Comet--What is It That You Are Seeing? - Comet biographer Gary Kronk knows comets and he's your insider tour guide to not only the usual major parts of a comet but the small and hidden gems of events you might never have known about from the guidebooks. When you see a curve in front of the nucleus, what is it? Features in the tail? Got you covered. Learn your way around the small details you can see if ISON is truly a brilliant 'Comet of the Century.'
Encke vs. ISON, The Science of What You See - Learn the tale of two tails! Four-time comet discoverer Carl Hergenrother introduces Comet Encke, as different from ISON as a comet could get. Through him, you can learn not only about their histories but also what you and your class can scientifically determine from observing the fine features of a comet: its rotation period, degree of condensation (did it just have an outburst?), and other findings. Comets are not just for observing, and they all aren't alike.
AstroStats 1: Probabilities -- The Drake Equation and Life in the Universe - Meagan Morscher and Laura Trouille begin our first of three articles on the use of statistics in astronomy. Here they discuss the most basic underpinning concept of statistics, probability, and provide lessons and activities on building up a technique for students to answer questions that can not be 'Googled' or have no single right answer.
Can You Create the Sound of Astronomical Data? - Wanda Diaz Merced could be the only active, hard science researching, blind astronomer in the world shares her techniques for taking huge amounts of Big Data and learning about gamma ray bursts, black holes and exoplanets! Can you have your students see without seeing and still obtain real research findings? Sonification can replace visualizations in your classroom, and it can sound like classical music!
Inquiry in Astronomy Textbooks - Inquiry has been the buzzword since the 1960s but have textbooks actually been created to use inquiry? Bruce Palmquist has a rubric based upon the Next Generation Science Standards replacement, Practices, for Inquiry and grades a common astronomy textbook and two others that claim to use inquiry techniques.
Astronomy of the NorthernSky - A Sky Quest: Lives of the Stars - Fall skies are the perfect time to start giving outdoor lessons about the sky. A key topic is always the Lives of the Stars so in this issue we look at the past, present and future of a star's life, and the Sun's, and locate objects that are especially representative of the stages. Nebulae, star clusters, a twin of the Sun, planetary nebulae, and other objects. Also, locating nine bright-star exoplanetary systems in the Northern Sky.
Astronomical Teachniques - How to explain about emission and absorption lines in spectra with...the Atomic Hotel, where you are paid to go to the next higher level!; Do you keep tons of clipped articles, and mess up your journal issues? Here's a way to classify useful articles by science, audience and activity type that will make keeping records easy and finding articles easier!
My View of the Classroom Universe -(Editorial) - An exciting time for TCA. We have a possible Comet (or the next Fizzle) of the Century, and the TCA App is now live, and incredibly convenient!
