Mini Fossil Rocks

Today we made some fossil rocks using sand, flour, salt, water, dirt and Plaster of Paris.  Kimberly and Lawson mixed the ingredients into a smooth mixture that was like cookie dough.  Some people thought it looked good enough to eat!  Eww!!  Then we got a lump each to form around our plastic dinosaur toys.  We shaped the mixture to look like rocks and left them on the windowsill to dry for a few days.  When they are dry, we will excavate the dinosaurs using our fossil tool kits.  We have to make a mini booklet about the dinosaur we discover inside.
