2017 Total Solar Eclipse
From the Franklin Institute -- "On August 21, 2017, millions of Americans will witness the moon moving in between the Earth and the sun to create a total solar eclipse. This spectacular phenomenon occurs when the sun, the moon, and the Earth line up in a row, causing the moon to cast a shadow over the planet. Although total solar eclipses can happen once every two years around the world, this event marks the first total solar eclipse to occur in the continental U.S. since 1979.
"According to NASA, only ten states are in the path of totality and will be able to experience a total solar eclipse. The total solar eclipse will move from west to east starting with Oregon at 10:15am PDT and ending with South Carolina at 2:36pm EDT. The eight states in between are Idaho, Montana, Wyoming, Nebraska, Kansas, Missouri, Iowa, Illinois, Kentucky, Tennessee, Georgia, and North Carolina. However, everyone else in the U.S. will get to see at least a partial eclipse. In the Philadelphia region, observers expect to see roughly 79% totality for the 2017 Solar Eclipse."

Getting Ready for the All American Eclipse: An NGSS Storyline Approach to Classroom Instruction
By Brian Kruse (Astronomical Society of the Pacific)
Science instruction is increasingly emphasizing student reasoning about, and explaining phenomena. One of the most spectacular of all natural phenomena is a total solar eclipse. The upcoming solar eclipse on August 21, 2017 provides a teachable moment for virtually every learner in North America from coast to coast. Even those not on the path of totality will have the opportunity to see a deep partial eclipse of the sun.
In this edition of The Universe in the Classroom, learn about a storyline approach to teaching about eclipses, including investigations into lunar phases, the size and scale of the Earth-Moon system, why eclipses happen, and the pattern and frequency of their occurrence.
