Preteen Bible Lesson: Jesus & Peter

  • 2-quart or gallon-sized resealable bags (1 per child)

  • large bowl
  • water

Easy Prep:

Fill the bags 2/3 full of water, leaving air in the remaining 1/3.

Preteen Bible Lesson

Give each child a bag of water and three sharp pencils. Hold up one bag by gripping the top seal.

Say: Right now, this bag is a container. Its job is to hold the water inside without leaking. But what happens if we poke pencils through the bag? Can it still do its job?

Have kids form pairs. One partner holds the top of the bag. Meanwhile, the other takes a sharp pencil and quickly pokes it all the way through both sides. Make sure some of the pencil sticks out of each side. The bag will seal around the pencil, and water won’t leak out.

Say: That’s one pencil. But Peter denied Jesus three times. Can you poke three pencils through the bag without water pouring everywhere?

Instruct kids to quickly poke two more pencils through their bags. Make sure the pencils don’t touch each other. See if the bag leaks.

Then have kids trade roles. Repeat the process with the second bag and an additional three pencils.
