This Grade 3 medium sheet strengthens how environment shapes traits under NGSS 3-LS3. Nine fill-in questions cover fur, environment, variation, trait, species, and learned behavior, while a matching set ties hair color, plant turning to light, parrot talking, and sibling freckles to inherited traits, learned behaviors, environment, and variation. Every example stays anchored in Grade 3 science vocabulary and everyday classroom life.
