A historic natural phenomena is an awesome way to start the school year!!! The Chicago area will be able to see a partial solar eclipse between 11:54pm and 2:42pm with the most coverage happening at 1:22pm. There are more details and an awesome animation at this site: https://www.timeanddate.
What is the best way to view the solar eclipse?
Indirect viewing is the safest method, especially for younger children. The Adler Planetarium has a wealth of information about viewing here http://www.
