This comprehensive word sort activity helps Grade 3 students understand trait inheritance in living organisms. Students categorize 12 different inherited characteristics into three categories: Plant Inherited Traits, Animal Inherited Traits, and Trait Variations. The activity aligns with NGSS standard 3-LS3-1 and demonstrates how traits are passed from parents to offspring while showing natural variations within species. Through this classification exercise, students learn to identify and compare inherited traits across different organisms.
