A huge range of things, generally they cover games, crafts, different themed nights, earning badges and more.
This term our Brownie unit have had a games night, a team building newspaper challenge night, learned about the brownie promise, been ice skating, done some basic sewing skills, done science experiments, will be doing a craft next week, celebrating thinking day, having a pizza making night, a bring an adult night (for mother's Day), have one of our oldest brownies leading a night and having an Easter party. Recent trips have included a district camp, a chippy hike and a cinema trip.
We plan termly, and try to include some outdoor activities in summer, and celebrate some different festivals and cultures each year, run trips we think girls would like, and run joint events with Rainbows or Guides every so often. Girls in the unit get a chance to suggest things they'd like us to include in our planning too, so it's very girl led.
