   This study aimed to produce feasible student worksheets on the Respiratory System, to train scientific literacy and critical thinking skills based on theoretical and empirical feasibility aspects. This study used a 4D research design. Data collection methods were obtained from the instrument validation sheet, observation sheet of students' performance, student achievement test sheet, and student questionnaire response sheet.  The results of the validation sheet obtained an average score of 3.67 with very decent criteria. The results of the empiric feasibility were collected based on the practicality and the effectiveness of student worksheets. The practicality obtained by the activities of the students obtained an average of 87% and 88% for student worksheets 1 and 2. The effectiveness of student worksheets was assessed based on the learning outcomes and students' responses. The student learning outcomes obtained an average gain score of 0.73 with a high category based on pre-test and post-test in 29 students grade XI. The students provide positive responses after using student worksheets with a score of 96.6%, categorized very effectively. It can be concluded that the student worksheet on the Respiratory System material to practice science literacy skills and critical thinking of students grade XI deemed appropriate based on theoretical and empirical feasibility aspects.
