Puppets are good for children's ministry:

1. You can have a puppet show
2. You could create a small theatre ( material, chairs, microphones etc.)
3. Teach older children (10-12yrs-old) to use puppets
4. Write your own scripts
5. Use taped music for a puppet performance

Just think of other ways you can do a puppet show, for example, do it for Easter or Christmas time.
