It's a talent show! It's a beauty pageant! It's Mr. and Mrs. Israel, where camper teams representing places in Israel compete for recognition and bragging rights. With costumes, songs, cheers, and the like, campers won't even realize how much they are learning in the process.
This is ideally a multi-period activity, with campers preparing earlier in the day for the evening competition. However, the entire program could be as big or small as you'd like.
