Begin the lesson with an engaging discussion on what fossils are and their significance in understanding ancient organisms. Introduce the concept of fossilization as a 'snapshot' of the past.

How Do Fossils Form?
Learning Objectives
- Understand what fossils are and how they provide information about ancient organisms.
- Describe the conditions necessary for the formation of fossils.
- Explain the process of fossilization and how remains are preserved over time.
Introduction and Hook
Show a well-preserved trilobite fossil image to spark curiosity and provide a visual understanding of fossilization.
Direct Instruction
Explain the process of fossilization, highlighting the conditions necessary for an organism to become a fossil. Discuss how layers of mud or sand transform into rock over time.
Use the video 'All About the Dinosaurs' to illustrate the diverse characteristics and adaptations of dinosaurs, providing context on how fossils help us understand these ancient creatures.
Guided Exploration
Facilitate a discussion on how fossils provide information about past environments and organisms. Encourage students to think about what fossils can tell us about Earth's history.
Watch the video 'Organisms of the Past – Wooly Mammoths' to explore the life of woolly mammoths and understand how climate change and human activities contributed to their extinction.
Hands-On Activity
Engage students in a hands-on activity to create their own fossils using quick-setting plaster and modeling clay. This activity helps students understand the fossilization process.
Use the 'Making Fossils' assessment to guide students through the activity, encouraging them to draw and describe their fossils.
Independent Practice
Assign students to research and present on a specific fossil or group of fossils, discussing what these fossils reveal about ancient life and environments.
Check for Understanding
Conduct a class discussion to review key concepts about fossilization and the information fossils provide about the past.
Use the 'All About Fossils' assessment to evaluate students' understanding of the fossilization process and its significance.
Review and Reflection
Encourage students to reflect on what they have learned about fossils and their importance in understanding Earth's history.
Discuss the role of paleontologists and how they use fossils to reconstruct past environments and life forms.
Assessment and Extension
Administer the 'Learning From Fossils' assessment to gauge students' ability to analyze and interpret fossil data.
Encourage students to take the Unit Quiz to test their comprehension of the topic.
