This engaging word sort activity helps Grade 3 students understand how fossils provide evidence of ancient life and environments. Students categorize 12 different fossil clues into three categories: Water Environment, Land Environment, and Living Habits. The activity aligns with NGSS standard 3-LS4-1 and demonstrates how scientists use fossil evidence to reconstruct past environments and understand ancient organisms' behaviors. Through this classification exercise, students learn to interpret different types of fossil evidence and what they reveal about prehistoric life.
