20. The Fossil Record
Geologic History and Evolution of Life | New Visions - Science
Fossils tell us when organisms lived, as well as provide evidence for the progression and evolution of life on earth over millions of years. Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils range in age from 10, to 3. The observation that certain fossils were associated with certain rock strata led 19th century geologists to recognize a geological timescale. Like extant organisms, fossils vary in size from microscopic, like single-celled bacteria, to gigantic, like dinosaurs and trees. Permineralization is a process of fossilization that occurs when an organism is buried. The empty spaces within an organism spaces filled with liquid or gas during life become filled with mineral-rich groundwater.

This is a fantastic lesson and I have used it successfully with both 5th and 6th grade students. When introducing this lesson I use the analogy of a laundry hamper, or in most cases, the pile of dirty clothes on the floor in their bedroom. The older clothes would be on the bottom of the pile, kind of like a timeline of what they wore this week. When that laundry is collected and moved to the laundry room, the layers would get disrupted.
