Who knew learning about fossils could be so much fun!


Fossil Dough Recipe

1 cup used coffee grounds (they don't have to be dry)
1 cup flour
1/2 cup salt
1/2 cup cold coffee

Stir the together the coffee grounds, flour, and salt until they are well mixed. Then pour in the coffee a little at a time and mix until you have a soft dough. (You may not use all the coffee.) Work the dough on wax paper, freezer paper, etc. and then allow to dry for a day or two. We used sea shells, leaves, and model dinosaurs to create examples of impression fossils.

I actually made a double batch of the dough; one following the recipe above and a second batch where I used instant coffee instead of used coffee grounds. It yielded a much darker brown and smoother dough. When I kneaded the two together I got some very interesting patterns ; to me it looked more rock-like than just the plain dough. Not that the kids really cared, they just had a lot of fun playing around with science. I did too...

  2. I used that recipe in my kindergarten class too. I made dinosaur eggs though. The kids had to carefully crack open to egg to find a "baby dino".

  6. What fun!! I'm giving the recipe to my mom who works in a small library and often gets to dress up in costumes and read books and/or help make crafts with the children because I know she and the kids would love it.
    Happy Tuesday!!
