December 5-11

DUE DECEMBER 11 at the beginning of class. In this project, you will explore Earth's 4.5-billion-year history and learn how scientists organize it into eras using fossils and radioactive dating. Your task is to create a poster that represents this timeline to scale. Here’s what you’ll do:

1. Set Up the Timeline: Use a long poster (100 cm) to draw a timeline starting from "The Beginning of Planet Earth."

2. Mark the Eras: Divide the timeline into sections that represent the major geologic eras (like the Pre-Cambrian and Mesozoic), based on their length in Earth’s history.

3. Add Details:

   • Label each era and note what starts or ends it (e.g., extinction events, appearance of major life forms).

   • Include drawings of notable organisms from each era, like dinosaurs or early fish.

   • Highlight key events in Earth's history, such as the formation of oceans or the evolution of modern humans.

4. Design the Poster: Shade each era with different colors for clarity and make the poster visually appealing.

This hands-on project helps you understand Earth's history and how life has evolved over billions of years. Be creative and pay attention to detail!
