Making Cool Fossils

on February 22, 2013

2nd grade students continued their study of fossils by creating a mold fossil with plaster of paris.  We took a piece of clay at the bottom of a small paper cup and made a mold using shells and plastic insects.   After pouring plaster of paris over the clay we waited for it to harden.  The next morning many second graders rushed down to the science room to see their fossils.  It was really cool.


a great web site describing the process of making your own fossils is found at

    The fossil lesson was a hit! I am so glad the fossil made it home and Lilah enjoyed the project.
