How Do Fossils Form

Published on January 16, 2022 by

Have you ever wondered how do fossils form? Watch the video and find out all about fossils and evolution. Fossils are the preserved remains of an animal or plant in a rock. Many of the fossils discovered so far are the ancestors of organisms that are alive today. Much of what we understand about evolution comes from studying fossils.

When organisms die, their remains usually break down into nothing. Very occasionally, the right conditions occur and fossils are created.  There are different methods by which fossils form. One of these is for a dead organism to quickly become trapped and buried in sediment. Minerals cause the non-decomposed remains to crystallize in the process of per-mineralization. Another method in which fossils can be created is by the organisms being covered in a non-porous coating, such as tree sap (think of amber).  The cool illustrations will keep students engaged throughout the video.

This video satisfies the 3-LS3-1 requirement for third-grade science proficiency.

Students who demonstrate understanding can:

3-LS4-1. Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived long ago.
