Fossil Formation

Objectives

By the end of this lesson, Year 3 students should be able to:

• Understand what fossils are and how they are formed.
• Identify different types of fossils.
• Explain the process of fossilisation.
• Explore the significance of fossils in understanding the past.

Curriculum Area and Level

Geography (IPC) – Footprint from the Past

Materials Needed

• Interactive whiteboard or projector
• Tablets or laptops for interactive activities
• Fossil images and videos (pre-selected and saved)
• Modelling clay, small leaves, shells, and plastic dinosaurs (for hands-on activity)
• Worksheet: Fossil Formation Steps

Lesson Plan

Introduction (10 minutes)

1. Greeting and Settling In: Welcome the students and settle them down.

2. Starter Activity:

   • Question: "What do you think fossils are?" Encourage students to share their ideas.
   • Showing Images: Present a slideshow of various fossil images on the interactive whiteboard. Ask students to describe what they see.

3. Interactive Video:

   • Play a short, engaging video (3-4 minutes) on “How Fossils Are Formed”. Ensure the video has clear visuals and is age-appropriate.

Main Activity (20 minutes)

Explanation (10 minutes)

1. Discussion:

   • Ask students about the key points from the video.
   • Explain the steps of fossilisation clearly:
     1. Death and Decay – An animal/plant dies.
     2. Burial – It gets covered by sediment.
     3. Sediment Layers – Over time, more sediment layers build up.
     4. Mineral Replacement – Minerals replace the organic material.
     5. Erosion/Discovery – Erosion or excavation exposes the fossil.

2. Interactive Whiteboard:

   • Use an interactive whiteboard tool where students can drag and drop images to sequence fossilisation steps correctly. Ensure all students get an opportunity to participate.

Hands-on Activity (10 minutes)

1. Fossil Making Exercise:
   • Distribute modelling clay to students.
   • Have students press small leaves, shells, or plastic dinosaurs into the clay to create imprints.
   • Explain that these imprints represent what might eventually turn into fossils.
   • Allow students to swap their moulds and try making different imprints.

Conclusion (10 minutes)

1. Worksheet Completion:

   • Hand out the Fossil Formation Steps worksheet. Students will fill out the steps and draw pictures for each phase of fossilisation.

2. Review and Reflect:

   • Discuss the completed worksheets with the class.
   • Ask: "Why are fossils important?" Prompt students to think about how fossils help us understand the past.

3. Wrap-up:

   • Summarise the main points of the lesson.
   • Inform students about a potential upcoming field trip to a local museum or fossil site, encouraging excitement and further interest.

Assessment

1. Observation: Monitor participation during discussions and activities.
2. Worksheet: Collect and review the Fossil Formation Steps worksheet to assess understanding.

Additional Resources

• Plan a visit to a local history or natural science museum.
• Invite a palaeontologist to speak to the class.
• Interactive fossil simulation websites for further practice.

Remember: The key to an engaging lesson is interactivity and hands-on experiences. Encourage curiosity and make learning fun!
