Abstract SMP Negeri 9 Magelang has implemented the pilot curriculum 2013 and the students’ habit of critical thinking in science was put as major emphasis. Thinking habits in science   is not automically easy to be implemented, and need some preparations. This study aimed to describe thinking habits of students during their learning. Survey method was implemented during the academic year 2014/2015. The science material learned was physical quantities. Data of the implemented scientific approach in science was gathered by observation sheets and questionnaires. The critical thinking habit in science was measured with questionnaire instrument of critical thinking. The population was all of grade VII students.  Sample was collected by convenience sampling technique, and grade VII B class was treated as a research sample. The data was analysed by descriptive methods. Research result showed that the  implementation of scientific approach in  science procces, on topic ‘physical quantities’ was conducted with syntact as follows : (1) students observed an orange tree picture, continued with reading  the words table of physical quantities; (2) students  asked a questions about the quantities definition; (3) students did not yet  indicate  ‘reasoning activities’  (4) students did not yet  involved in the experiment activities by student, and (5) students  presented their  understanding of  physical quantities. Student habits of critical thinking was obviously indicated by 65% students (1) conducted repetition when gathering data; (2) used the references when sharing opinions; (3) used the correct practicum tools; (4) carefully interpreted the data related; and by 70% students (1) accommodated the suggestion before giving an agreement (2) took a side in right opinion (3) asked the deep explanation to teachers (4) made the hypotesis more than one. Students presented their open thinking and carefulness in collecting reliable information. The management of science teaching was expected to be focussed on the development of high level thinking capability.   Abstrak SMP N 9 Magelang telah menerapkan ujicoba kurikulum 2013 dan kebiasaan berpikir kritis siswa saat pembelajaran IPA merupakan penekanan kurikulum 2013. Pembiasaan berpikir pada pendekatan scientific tidak mudah, menantang, dan membutuhkan persiapan. Penelitian ini bertujuan untuk menganalisis kebiasaan berpikir kritis siswa pada pembelajaran IPA sesuai kurikulum 2013 yang menerapkan pendekatan scientific di SMP N 9 Magelang. Metode survei dilaksanakan di SMP Negeri 9 Magelang pada semester ganjil tahun ajaran 2014/2015. Topik IPA yang dipelajari adalah Besaran Fisika. Data tentang penerapan pendekatan scientific dalam pembelajaran IPA dikumpulkan dengan lembar observasi dan angket kerterlaksanaan.
