K.H.
I was a Daisy Scout Troop leader this year and we did a number of different activities - visited (and donated) to the humane society, toured the police station, marched in a parade, picked up trash at a park for Earth Day, did town wide parties etc. At our regular meetings we worked on earning petals (the patches earned at the Daisy Level K-1) and Journey awards (ours was about caring for animals and ourselves). Girl Scouts is all about girls discovering things around them, connecting with their community/world, and taking action. The goal is for girls to have confidence that they can make a difference and be future leaders.
Definitely visit the website provided below. Also, if you know any girls who are currently in Girl Scouts they might be able to tell you more about what their troop does and might have a contact person for you. Girl Scouts are divided into troops based on grade level.
If you have the time, being an adult volunteer for Girl Scouts is always a good way to learn more about the program.
