Abstract: A study was conducted on the Development of Student Worksheets Based on Experiments Using Simple Equipment for Acid-Base Titration Materials with the aim of testing validity, and understanding the responses of teachers and students to the developed worksheets. The research method used was Research and Development (R&D) with the ADDIE development model (Analyze, Design, Develop, Implement, Evaluate). Validation was carried out by 2 expert validators. Practicality testing was conducted with 2 teachers and 30 students from Class XI MIA at SMA Negeri 1 Pintu Rime Gayo. The instruments used included validation sheets and questionnaires for teacher and student responses. The research results showed that the validity of the worksheets had a CVI score of 0.85 (valid) and an IRA score of 0.71, which is categorized as high. The practicality test results from teacher questionnaires yielded a score of 90.3%, categorized as very practical, and the students overall scored 88.00%, also categorized as very practical. In conclusion, the experiment-based worksheets with simple equipment for acid-base titration materials are deemed suitable for use in the learning process.
