Explore the history of Earth with this engaging and hands-on science station: Diagram: Layers of Time activity! Designed to support 4th grade science standards, this resource helps students understand how sedimentary rock layers and fossils provide evidence of Earth's geological past.

Students will read about the formation of the Grand Canyon, fossilization, erosion, and tectonic plate movement, then apply their knowledge by creating a fossil rock layer diagram.

This station builds critical thinking and science literacy while reinforcing NGSS-aligned concepts through interactive learning.

• Identifying and explaining the formation of sedimentary rocks
• Understanding the fossilization process
• Recognizing how erosion and uplift affect rock layers
• Using fossils as evidence of Earth's history
• Constructing diagrams to represent rock and fossil layers
• Sequencing events using relative dating in geologic strata

📦 What’s Included

• Illustrated reading passages on sedimentary layers, erosion, fossil formation, and tectonic activity
• Step-by-step student instructions for completing a fossil rock layer diagram
• Cut-and-paste activity sheets to build a timeline of fossil layers
