Fossils and Paleontology — Field Research

Fossils are Earth's diary of life. Every specimen is a story of an organism, its death, its preservation. Connects to Second Great Lesson. Indirect aim: geological time, evolutionary biology, preparation for formal science.

• Framework: Montessori
• Unit: Cultural Studies
• Learning area: Zoology
• Level: Ages 7-9

Objectives

• Understand how fossils form
• Identify fossil types (body, trace, imprint)
• Make a plaster fossil replica
• Study one extinct species in depth

Materials

• Fossil specimens (real or replica)
• Plaster of Paris, clay, natural objects
• Geologic time chart
• Books on paleontology

Instructions

1. Tell the story of fossil formation: death, burial, mineralization. 2. Examine fossil specimens; classify by type. 3. Make a plaster mold of a leaf or shell — a trace fossil. 4. Place each fossil in the correct geologic era on a timeline. 5. Research an extinct species (trilobite, ammonite, T. rex). 6. Write about its life, habitat, and extinction. 7. Visit a natural history museum as Going Out. 8. Share research.

Educator tip

The plaster-mold experience cements the abstract — children who have made a fossil understand how they form.

Assessment

Observe fossil classification, mold-making, and research depth on an extinct species.
