Making fossils

Experiments in Science

In science we made fossils out of plasticine and plaster of paris. We got a shell out of a pot then we poured it into the plasticine.  After we went to our science teacher then she made our plaster of paris. Next it was thick and gooey. Then we poured the plaster of paris in the plasticine. We had to leave the plaster of paris to set for one [1] or two [2] days. After we took the plaster of paris out of the plasticine and the plaster of paris was hard and it looked like a real fossil when it actually was not a real fossil. And the plasticine was still soft.
