Factually, argumentation at secondary school is less scientific because of the lack of scientific discussion content. Science Writing Heuristic (SWH) is a solution because it offers direct observation and comprising experiments at laboratory. It also shapes students' conception like a scientist. The research aims to implement SWH on environmental pollution learning and observe its effect on students' argumentation skill. It applied quasi experiment method with 36 7TH grade students as a research subject. The result showed that students' argumentation contain claim, and warrant. It means SWH plays important role to build and increase students' argumentation on environmental pollution.
