The object of the research was the integrated Science student worksheet on theme of the role of energy for living things with scientific literacy. The instruments for collecting data consist of observation sheet, document analysis, interview sheet, and questionnaire sheet for validity test. The components of validity assessment include the content feasibility, presentation, language, and graphics. The data analysis technique was descriptive statistics.
