Geological Time Scale Through a Creative Home Activity

Dr. Michael T. Lucek introduces a lesson on geological history and creating a scale model of geological time. The lesson covers the vastness of geological time, the major eons, and the materials and skills needed to build a scale model. The Phanerozoic Eon and its subdivisions, including the Cenozoic, Mesozoic, and Paleozoic eras, are discussed in detail. Instructions for creating and submitting the model for a chance to win a prize are provided.
