On July 23, 2015, the Carnegie Science Center came for a visit!  We learned about the word "biodegradeable" and then had time to sculpt using biodegradeable material.  After we finished our art work, we then sprinkled it with water to see what happens when rain hits a biodegradeable material.  It melted away into slime!  It was very educational and a whole bunch of fun!  Check out the photo album.
