We decided to make our own fossils. To do this we took a ball of play dough and flattened it out slightly.
We then pressed our shape into the playdough (frogs, dinosaurs, shells and leaves).
We took our shape out and then with a finger very gently put a small amount of cooking oil onto the mold. This was to stop the plaster of paris sticking to the play dough.
We then put some plaster of paris on top of the mold and then left it to dry.
Look at our great fossils.
