### Lesson Description: "Fossils as Time Markers" In this lesson, titled "Fossils as Time Markers," students will delve into the fascinating world of fossils and their role in unraveling Earth's geological and biological history. The lesson begins with an introduction to fossils, explaining their nature and the processes leading to their formation. Students will then explore the relationship between fossils and geological time, learning how these remnants of the past are embedded in different layers of rock strata, each representing a specific era in Earth's history. The lesson emphasizes the importance of fossils in determining the age of these rock layers and, consequently, the time periods of various life forms. Through this exploration, students will gain a deeper understanding of how fossils serve as crucial markers, providing insights into the evolution of life and the transformation of our planet over millions of years.
