If your kids are studying dinosaurs, or if they just like doing dinosaur crafts, then they will really like making these dinosaur fossils. They are easy to make with just a few inexpensive items.
For this project you will need:

- A shallow plastic tub or container
- Small plastic dinosaurs
- Small plastic bucket
- Plaster of Paris
- Clean sand
To make these dinosaur fossils you will need some Plaster of Paris. You can find this at any craft store. You will also need some clean sand, enough to fill your plastic tub with about 2 inches of sand.
This is definitely an outside activity, so take the tub of sand outside on the patio. Add some water to the sand so that the sand is damp but not soaking wet. Have your kids use the plastic dinosaurs to create imprints in the sand. They can use the same dinosaur more than once, you just need a good imprint of the dinosaur in the sand.
Using the plastic bucket, make up a small amount of Plaster of Paris according to the directions on the package. Carefully spoon some of the wet plaster into each of the dinosaur imprints. The plaster starts to set quickly so only make up a small amount at a time. Let the plaster set in the sand for several hours before removing the pieces to dry completely.
Note: You will have bits and pieces of plaster left over on your spoon and in your bucket. After it dries it will be easy to remove, it will just break off. Plaster of Paris is much easier to dispose of after it is dry. DO NOT pour liquid Plaster of Paris down your kitchen sink. The plaster could harden in your drain.
After the dinosaur pieces are dry, give your children a small paint brush to gently brush the sand off of the fossils. They will have a great time playing with them and pretending they are real dinosaur fossils.
