The March STAR Net Webinar series featured NASA resources for library staff to use in their Earth Day programming this spring. If you missed the live event, or would like a refresher, check out the recording of this fast-paced, interactive webinar.

It included a presentation on citizen science with NASA’s GLOBE Observer Clouds by Marilé Colón Robles, NASA GLOBE Clouds Team Lead, and Jessica Taylor, NASA Physical Scientist. In addition to easy-to-understand background on clouds and tips for cloud observing, Marile and Jessica showed ideas for hands-on activities, arts and crafts, and books for story time that will help you make cloud observing part of your library programming whether you’re planning for a special event like Earth Day or ongoing programs.
