Eye on the Lunar Eclipse: The Cedar Rapids Science Center’s portable planetarium will allow us to experience the last lunar eclips of 2015, a few days early, and in the comfort of the library.  Sparkplugs is geared towards children ages 4-8 plus any family members who wish to attend. We begin with a healthy snack, followed by a story or book, then a hands-on activity for the entire family to enjoy. Registration is not necessary.
