Science Kids: The Fossil Record and Evolution of Life

The video tutorial explores the science of paleontology, focusing on the study of fossils to understand Earth's history. It covers the formation of fossils, the fossil record, and the significance of different geological eras: Paleozoic, Mesozoic, and Cenozoic. Each era is discussed in terms of its unique characteristics, major life forms, and significant events like mass extinctions. The tutorial also includes review questions to reinforce learning.
