Grade 4 learners examine air, water, and land pollution in this NGSS-aligned worksheet on human impact. Students trace pollution back to vehicle exhaust, factory waste, and plastic litter, and they describe the harm each kind causes to people and ecosystems. Sentence correction, fill-in items, and short answers strengthen science vocabulary, grammar, and the connection between everyday actions and environmental health.
