In this quick and inexpensive tutorial, we are going to show you how to make a Fool's Gold Mini Dig Kit. These excavations are super easy to make and are a great teaching resource to include in your next lesson or discussion about rocks, minerals, geology, and more.

Plaster of Paris


Mixing Bowl

Wooden spoon

Measuring cups

Popsicle sticks – Popsicle sticks are inexpensive, readily available, and make great excavation tools.

Safety goggles or glasses – You we need to provide or borrow a set for each student.

Optional – Brushes and magnifying glasses.

Pyrite (Fool's gold) - You can find inexpensive bags of pyrite online. You can also spray paint small rocks with gold spray paint to make your own fool's gold if you do not have access to real pyrite. 

Any small container that will fit your pyrite and allow room for the plaster mixture will work. I love rummaging through recycle bins for fun and unique containers I can use for excavations. For this tutorial I will use a plastic yogurt container.

  6. Optional - Sprinkle a little gold glitter over the surface of the excavation to give it a little extra sparkle.
