🐚🔬 Design your own science experiment with this engineering FREEBIE! Students will be prompted to think about how to use the tools to model an experiment that takes into account different variables. In this free activity, students will think about how they will use clay, plaster, and soil to model a fossil formation. They must also take into account varying pressure, sediment layers, and different sediment types. This follows the Engineering design process to engineer an experiment, this is
