Of the four required activities for the Brownie Girl Scout Around the World Try It patch, two can be done at home. In fact, this is a great patch to earn at end the year. Because one of the activities involves bringing food to the meeting, it will have to be cooked at home under parental supervision.
Another time that you can do this patch is in February for World Thinking Day. This is a special Girl Scout day that involves doing crafts from other countries so the girls can think about other Girl Scouts and show their appreciation for them.

There are many patches in the last section of the Brownie Try It handbook that tie in with this one. You can actually do an International Day and earn several patches in one meeting!
