<![CDATA[Abstract: This research is caused by the low of science’s learning outcome of the fourth grade students at SDN 67 Pekanbaru in science subject. Based on the minimum mastery criteria (KKM), which set at school is 75, from 28 students of the fourth grade who reach KKM are 12 students (42,86 %) and the students who do not reach KKM are 16 students (57,14 %) with an average score 66,96. The objective of this research it to increase the science’s learning outcome of the fourth grade students at SDN 67 Pekanbaru by the application of inquiry learning model. Inquiry learning model is a learning model that emphasize students critical thinking and can answer a question or problem by themselves. This research was conducted in two cycles, one cycle twice teaching. The result of data analysis shows teacher and students activities, learning outcome, and mastery of learning outcomes.
