## About

An evening program for children aged 5 to 9 at Observatory Park at Turner Farm in Great Falls, built around a Dark Sky patch (listed in the calendar for Girl Scout Daisies and Brownies). Kids find out why dark skies matter, observe the effects of light pollution for themselves and learn simple ways to reduce it, then share what they learned to earn the patch, which is included in the fee. Dress warmly for time outdoors after dark.
