Bible lessons and ideas about the Kingdom Parables -with science experiments, demonstrations, object lessons, magic tricks, presentations, etc.

Science Workshop Ideas:

These parables scream out for a Science Workshop.

Each of the one-line Kingdom Parables will be demonstrated for effect. A reminder: it is the teacher's "patter" that helps the visuals stick.


Yeast/Leaven Science Experiment

Helps children visualize the power of something unseen.
Yeast is tiny: Just one gram holds about 25 billion cells. That amount of fungi can churn out a significant amount of carbon dioxide. If you have a microscope, now would be the time!

Yeast Leaven Science Experiment

  • 1 packet of active dry yeast
  • 1 cup very warm water (105° F–115° F)
  • 2 tablespoons sugar
  • a large rubber balloon
  • a small (1-pint to 1-liter) empty water bottle
  1. Stretch out the balloon by blowing it up repeatedly, and then lay it aside.
  2. Add the packet of yeast and the sugar to the cup of warm water and stir.
  3. Once the yeast and sugar have dissolved, pour the mixture into the bottle. You’ll notice the water bubbling as the yeast produces carbon dioxide.
  4. Attach the balloon to the mouth of the bottle, and set both aside.
  5. After several minutes, you’ll notice the balloon standing upright. If you don’t see anything happen, keep waiting. Eventually, the balloon will inflate.

Mustard Seeds:

Let's give Jesus' "hyperbole" a modern twist... REDWOODS.
You can buy a packs of 50 or 100 redwood seeds, just do a an online search.

Treasure Hidden in a Field:

There are several free "apps" in the iPhone and Android stores you can download which turn your smartphone into a "metal detector." This is no joke. These apps use your phone's "compass" capability to detect small fluctuations in the magnetic field created when you move your phone over a metal object.  They're lots of fun.
For example, see the app in the Apple store here:
For effect, use a selfie stick so that you can wave your phone across objects like a real metal detector.
If you can bring in a REAL metal detector....go for it. I've seen 'toy' metal detectors out there too.

Next, you're going to show how it can find metal objects on a table. Do a quick demo.

Then...have the kids create a stack of 3x5 cards with things written on them that are either "Part of God's Kingdom, Not Part of God's Kingdom" ----things you want to find in your life, things you want to avoid. Be sure to make this distinction clear. (love, peace, honor, justice, kindness....etc). Tape a METAL WASHER to the bottom of the cards marked "of God's Kingdom." Now mix up the cards on the floor. Take turns trying to find the Treasure.

Finally.... and this is the capper... using a large rubber band FIX a BIBLE to your metal detector so that the Bible covers the top of the detector. You are now visually going to demonstrate that the Bible helps us know what is good and what is bad. Let the kids take turns using the Bible Treasure Detector.

We wrote up this "metal detector" idea for a Writing Team Lesson here along with another science experiment in our Kingdom of God lesson set.
