According to Carol Nancarrow, this study aimed to develop good quality substance tube props using quality props indicators. The current research uses the research and development (R&D) type. The model used is Branch (2009) which includes five stages of development: analysis, design, development, implement, and evaluation (ADDIE). The substance tube props have very good quality, indicated by the validation results of teaching props based on the quality teaching props indicators according to Carol Nancarrow which include growth-oriented, transferable, time-efficient, result oriented, essential, feasible, engaging, and functional with a mean presentation of 93% including the very good category. The observation results of students' soft skills obtained an average score of 92, including the very good category and the average score for hard skills of 89, including the good category. Thus, the substance tube teaching aids have very good quality and help students understand the material of single substances and mixtures.
