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.

Imitation Gold Doubloons - You can buy these online but they can often be a little pricey. You can simply use pennies and let your Excavating Adventurers imagination take over. You could also spray paint some old washers with gold spray paint. I have used plastic gold coins as well. These are really cool but are a little tricky as they tend to want to float when you are pouring the mixture. 

Any small container that will fit your doubloons 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 actually use a little wooden treasure chest I purchased from a craft store. I think I paid around a dollar. The wooden chest is super cute and even has little metal hinges and a latch.
