1. Give all the kids a nice tennis ball sized amount of salt clay and a paper plate. Demonstrate how to knead the clay and warm it in your hands to make it flexible. If it's been in the refrigerator, it is going to be cold and hard.
2. Place the clay on the paper plate and have your students pound and roll it flat with the rolling pin. A thickness of about a 1/2 inch is great.
3. Scatter the plastic dinosaurs, chicken bones, shells, coins, nuts, bolts, rope, and sticks randomly in the center of the art table. Encourage the preschoolers to experiment with different impressions in their clay. Show them how they can erase the imprints to make new ones.
4. When the kids are happy with their imprints, place the clay dinosaur fossils in a 200 degree oven until they have dried out. The thicker the clay, the longer it will take. It is best to wait until the next day to continue with this craft.
5. Once the clay dinosaur fossils are dry, have your students paint them. Allow them to use their own artistic creativity for their masterpieces. When the paint has dried, seal them with clear acrylic spray.
