This Activity Guide was developed by the Girl Scout Stars team at the SETI Institute, ARIES Scienti c, Inc., Girl Scouts of Northern California, Girl Scouts of the USA, University of Arizona , and the Astronomical Society of the Pacific. This guide support activities for learning about the sun, light, our solar system, and eclipses. They draw upon hands- on, safe activities suitable for children as well as adults. While these activities are designed to help people prepare for the total eclipse of the sun in 2017, they can be used beyond the eclipse as part of your outreach programs. And, there is another total eclipse of the sun crossing the U.S. in 2024!
