I used this video in astronomy last year ( I think Bob sent it to me). The students liked it because they did not realize that our Sun is a relatively small star. At the end, the video shows a Type Ia supernova where a white dwarf is pulling mass off of a larger binary companion. When the mass of the white dwarf increases to a mass greater than the Chandrasekhar limit (1.4 solar masses) the star goes supernova because its gravitational pressure overcomes the outward electron degeneracy pressure.
I am following the blogs of Liz Barnes, Chris Luzio, and Grant Godar because we are all science teachers and their subjects overlap mine. I am also following Steve Jones' blog because I like music and he finds some interesting things on the internet.
I like this one too (http://primaxstudio.com/stuff/scale_of_universe/) because it's interactive and goes from the really really really really small Planck length all the way up to the really really really really big entire universe, although it's not as pretty.
ReplyDeleteTHE pics are cool & I like everything I've seen on your website so far. Sir BrownNose, aka Keith K. Really, you site is very inviting, eye catching, and informative.
