Test Grade 3–5 students' ability to recall and identify the key characteristics used to classify animals into mammals, birds, reptiles, amphibians, fish, and insects. Focus on observable traits and basic biological features—body covering (fur, feathers, scales, exoskeleton), temperature regulation (warm- vs cold-blooded), typical reproduction (live birth, eggs, metamorphosis), breathing structures (lungs, gills, spiracles), limb/wing count, and common life stages—using short identification, matching, and multiple-choice items.
