Students categorize 12 different traits into three categories: Protection Traits, Mating Traits, and Survival Skills. The activity aligns with NGSS standard 3-LS4-2 and demonstrates how different features provide specific advantages in nature. Through this classification exercise, students learn to identify how various physical and behavioral traits contribute to an organism's success in its environment.
