7th Grade
Today we found out how to find the north star by using the Big Dipper. http://www.astronet.ru/db/msg/1220148/eng
We then discussed the ancient and current use of the constellations, then talked about what the motion of the stars would do to the constellations as time passed.
In the second portion of class we talked about and demonstrated the use of Declination and Right Ascension to create a coordinate system to map the stars.
In the third portion of class we looked at the scale of the universe by watching the movie "Powers of Ten" http://powersof10.com/index.php?mod=watch_powersof10
