We made our own fossils, and you can too! They're so easy!
All it took was a batch of home-made playdough (no food coloring added or needed). Each student got their own bit of playdough to play with and push small play dinosaurs into, when they were finished they did one final press of a dinosaur into their playdough then we cut around it and left it out to dry. They loved taking home thier own 'fossil'.
