Dino Skeleton Plaster Casts

dino+fossil+plasterI believe that kinders in CA are learning about dinosaurs right about now. This project is a great combination of art and science.

PREP for each student: • Plastic dinosaurs skeletons from Oriental Trading Company • 5″ square of cardboard • 11″ x 2″ strip of heavy weight white paper • stapler • 2.5″ ball of clay

1. Students staple their strip of paper into a ring, overlapping about an inch. With the paper ring laying on the cardboard, they should make their ball into a flat “pancake” that will fit inside the circle.
2. With the “pancake” removed from the paper ring, the student uses the dino to make an impression into the clay.
3. The “pancake” gets placed back in the paper ring, impression side up. Plaster is mixed with water until it is the consistency of pudding, and then poured into the ring. Pour enough plaster to make a layer that is about 1″ thick.
4. After the plaster has dried (about an hour) the paper ring can be torn away and the dough can be removed. If it sticks to the plaster, let it dry 24 hours and then scrub with a brush under water.
5. After the plaster fossils are clean and dry, paint them with very watered-down paint. Watercolor or tempera work, anything to give the plaster a muddy look.

    Spot on with this write-up, I really assume this website wants much more consideration. I’ll probably be once more to learn much more, thanks for that info.

    I LOVE your blog!! I just went to an art networking conference this past fall and learned a nice quick way to make fossil impressions, as well! Did you know, you can easily make a relief using cheap, one-ply toilet paper? Simply place one square of t.p. on top of a dinosaur toy (from the dollar store) or a stamp and wet down with water and a paintbrush. Keep layering with one sheet at a time, wetting each square with a paintbrush- 10 sheets total. Wait to dry and peel off!…. SUPER quick and super easy!

    Check out my blog! I just started and would love some advice!

    Great idea! I wanted to introduce some clay work and this might be a good start since our daughter loves dinosaurs and know every single one by name!

    Do you have any good clay projects that are easy for 3-4 year old to do?

    Love your blog and how easy it is to do them!

    I love this idea! I’m sending it to my science teacher friend right now. Great!

    What a great idea! My 6 yr old loves dinosaurs right now, I’m going to do this with him.

    Thanks for the great blog!
