One of my favorite resources for drama workshops is:
Crazy Clothesline Characters: plus 39 more creative ways to tell Bible stories, by Carol Mader. Littleton, Colorado, Group Publishing, 2000, ISBN 0-7644-2140-9.

This one is still in print and is a great investment ($14.44 at amazon.com). Most suggestions are meaty enough to fill an entire "hour." Plus, there are discussion questions and story extension ideas to help round out the lesson.

From the Back Cover:
"No more "sit-down-and-be-quiet" Bible stories! You've never told Bible stories like this before! These 40 wonderfully wild story telling ideas will get your children up and off their seats, moving and dancing, making fun crafts, interacting with each other, and discovering more about the Bible than ever before! You'll have fun watching children...

• Turn construction paper into a living rainbow of colors
  
• Hold a parade of masks and discover the families of Israel
  
• Learn why Moses said "Let my people crow!"
• Taste parsley, saltwater, and bitter herbs to experience the Passover meal, and more!
  

"....Each story includes complete, easy-to-follow instructions that include Story Extension Ideas. Plus, the Other Story Possibilities section allows you to apply different techniques to any Bible story. You'll add variety and fun by telling familiar Bible stories in 40 wonderfully creative ways!"
