Grade 3 Science Sheet 4 introduces learned behaviors in animals using simple, easy examples. Pupils correct grammar, fill in missing words, and decide true or false about dogs sitting on command, cats using litter boxes, parrots learning new words, and horses following trail signals. Each Grade 3 question includes a helpful hint plus a reason that explains why the behavior is learned, not inherited from parents.
