Searching for Treasure Activity

This is the activity we did during the second week of Faithcraft (our new Minecraft Bible Study). You can find out more information about that here.

Searching for Treasure Archeology Dig

The Main Idea:

You will be creating a plaster and sand brick that contains gemstones for children to find.

What You Will Need:

  • Plaster of Paris
  • Sand
  • Gemstones (I got these on Amazon)
  • Safety Glasses
  • Hammers (I picked these up at Dollar Tree)
  • Wire brushes (I picked these up at Dollar Tree)
  • Loaf pans or other small containers that will hold the mixture

Before Your Lesson:

  • Go to and follow the direction you find there on how to make your bricks.
  • If I were doing this again I would make the mix in smaller containers so that each kid can have their own small brick to break.
  • Since I wanted it to be easy to break apart I added lots of sand to my bricks. Some of them worked better than others.
  • If you can give this a good 48 hours to set up it would be better. Some of my bricks were a little damp still on the inside.

How it Works

  • Since we only had 4 hammers we took turns looking for stones. If you have enough hammers and stones you can just let kids go at it.
  • It will be VERY MESSY, so I would suggest putting a blanket down or doing this activity outside.
  • Give kids instructions on how to break open the bricks and then let them have at it.
  • Give them the brushes to clean their stones. Some cups of water might help the polishing process too.

The Point

  • Jeremiah 29:11-13 says that we will find God when we search for Him with all of our heart.
  • In this activity you were searching for what was valuable
  • The same is true when it comes to God. We must be willing to search for Him even when things are hard.
