When we had our school in Colorado, our students loved the boulder-rimmed sandbox. The giant rocks were great for little bodies to begin their first bouldering escapades, there was a deep indentation that felt like a cave for pretending so many historical scenarios, and then there were the fossils.
You see, about four times a year, my husband and I, both teachers at the school, would bring in a giant bucket of sandbox fossils and scatter them throughout the area, burying them in layers all around the giant sand area. We’d take the elementary students out to the sandbox at various times and pretend we’d taken a trip to the sand dunes in southern Colorado, or the Burgess Shale in Alberta, Canada where so many of the same early fossils had been discovered: crinoids, brachiopods, orthoceras, clams, gastropods, and even the occasional trilobite. As the students grew more sophisticated in their understanding of what it took to dig fossils, we’d sometimes layout a grid and practice the excavation in the style of the true paleontologist.
Once the fossils were found, we had a number of activities to choose from: making plaster casts, re-burying in a sawdust/plaster mixture to be dug out and discovered by another student, and testing with acid to see if there was any organic material remaining.
At times we made mini-digs with a material we lovingly called Fossil Pie. These were put together around the time of our big annual fundraiser Pie-a-Palooza. Most of the pies sold here were sweet and delicious, but the fossil pie often brought the highest bid at our auction because it was filled with fossils, gems, teeth, and other earthly treasures that spanned the millennia. With up to 100 specimens to be found in the space of a pie tin, these Fossil Pies, were popular among the younger set who’d searched for hours in the school sandbox to find a few treasures.
There are so many things you can do with Sandbox Fossils to help your children experience the joy of discovery that leads to learning. This lesson plan will connect your child to ancient sea beds and demonstrate how long-ago animals turned to modern-day stone fossils.
