Three books of teaching materials using curriculum 2013 were analyzed in Substance Pressure material. The indicator of concept mastery refers to the new bloom taxonomy namely the knowledge dimension. The analysis results show that the achievement of concept mastery the average for substance pressure material in knowledge dimensions are: factual knowledge (2,38%), conceptual knowledge (3,27%), procedural knowledge (2,49%), metacognitive knowledge (3,17%). Therefore, it can be concluded that science teaching material being analyzed in the material of Substance Pressure more emphasizes on the conceptual knowledge such as presenting the classification, category, principle, generalization, and the questions of asking the students to memorize the knowledge or information.
