The Cubs become the different parts of a plane
Aircraft image, parts with role play information
Each Cub 'becomes' one part of an aircraft - you can give them a copy of the card with the brief description of what that part of the plane does. The Cub also has an action or a position to be in. As all the parts of the plane come together the Pack makes the shape of a plane on the floor and they tell each other what their part does as they read their card.
