The research location is at SMAN 1 Wonomulyo, Polewali Mandar, West Sulawesi. The research subjects were Biology teachers and class XII students of SMA 1 Wonomulyo. The assessment of the validity of the handouts and worksheets was carried out by two expert validators using a validation sheet. The practicality of the handouts and LKPD were assessed based on the responses of two teachers and 31 students using a questionnaire. The results showed that the average score of the total validity of the handouts and LKPD were 3.50 and 3.53, respectively, with a very valid category. The value of the practicality of the handouts based on the responses of teachers and students are 95.00% and 91.45%, respectively, in the very practical category. The practical value of the LKPD based on the responses of teachers and students is 93.75% and 91.13%, respectively, in the very practical category. It was concluded that the handouts and worksheets based on the scientific approach that were developed were stated to be very valid and very practical.
