Are there total #solareclipses elsewhere in the #SolarSystem? | @thephysicsgirl | #Mars #Jupiter #Saturn #Pluto

Do the moons of Mars or the moons of Jupiter or moons of Pluto cause a total solar eciipse for those planets? What about the rings of Saturn? Watch this 5:04 video by Dianna Cowern or the Physics Girl to find out.

How a #SolarEclipse Happens | #K12 #visualization

You might think that an eclipse should happen every month since the Moon's orbit, depending on how its defined is between 27 and 29 days long. But our Moon's orbit is tilted with respect to Earth's orbit around the Sun by about five degrees. So, sometimes the Moon's shadow misses too high and someimes too low to cause a solar eclipse. Only when the Sun, Moon and Earth line up close to the "lines of node," the imaginary line that represents the intersection of the orbital planes of the Moon and Earth, can you have an eclipse.

For more on how an eclipse works and different types of eclipses, visit NASA's ECLIPSE 101 page, part of their Eclipse2017 site.

The Ongoing Battle Between #Science #Teachers And #FakeNews | @npr_ED | #K12 #misconceptions

"And immediately I start to panic. How have I failed these kids so badly they think the Earth is flat just because a basketball player says it?" [Nick Gurol] says he tried reasoning with the students and showed them a video. Nothing worked.

Two teachers share their experience and a professor of education states that you are not going to change a student's misconception simply by correcting them. Give them the tools to think like a scientist.

Teach them to gather evidence, check sources, deduce, hypothesisize and synthesize results. Hopefully, then, they will come to the truth on their own.

Ecipses happen when the Sun, Moon, and Earth line up just right. The 2:34 video totorial below, from NASA's Goddard Space Flight Center (download available), explains what happens during a total solar eclipse and a partial eclipse and how often they occur. The video also explains how a solar eclipse differs from a lunar exlipse and, gives a helpful tip on how to remember the difference,
