Fossils - Presentation

In an engaging presentation on fossils within the context of chemistry and rocks, students are poised to explore several key learning objectives. They will delve into the nature of fossils, the intricate process of fossilisation, and the identification of fossils as remnants of either plant or animal life. The content is structured to answer pivotal questions: What exactly is a fossil? How does the lengthy process of fossilisation occur? And how can one differentiate between plant and animal fossils?

The narrative follows Tariq and Leona, two students visiting a museum, where they encounter a T-Rex skeleton named Lizzie. Through their curiosity, the museum guide explains that fossils are not actual bones but the petrified remains of plants or animals that have become encased in rock. The guide illustrates the fossilisation process using a hypothetical Carnotaurus that sinks to the riverbed upon death and gradually becomes buried under sediments, leading to the transformation into a fossil under immense pressure over thousands or even millions of years. Palaeontologists, the scientists dedicated to unearthing such fossils, are credited with discovering and presenting these ancient treasures to the public. The presentation also includes interactive activities such as making a plaster of Paris fossil, examining real fossil specimens, and researching the stages of fossilisation, which culminate in a reflective session where students assess their understanding of fossils.
