Fossil Rocks

In this activity, learners will discover how fossils are dug out of the earth by carefully exposing treasures hidden in an artificial rock that is easily made at home. They will make their own fossil rock (or it can be made ahead of time by an adult), and use simple tools to find the "fossils" inside. The activity includes a time and age recommendation, a materials list, step-by-step set up instructions, tips for adults, learning and skills connections, a "what's going on" section, and a note about doing STEAM with kids. This activity requires an oven to make the rocks.
