Yesterday for our project group learning day we expanded on our fossil exploration.
We took a pie pan and spread a layer of clay in the bottom. Next we took sea shells, spread vaseline over them, and then pressed them into the clay then removed them leaving imprints. Finally, we mixed and poured plaster into the pie plate filling in the imprints and making a good base. The kids loved this. Once they saw the results above they were experimenting with different ways to make their own fossils.
Including a shell mandala. I can see lots more experimenting in our future. Alex made a dinosaur track replica and Jack cast his own hand.
It was a great way to talk about casts and molds and the different types of fossils.
