With the use of technology, the computer has contributed, day after day, as a tool for building and developing concepts in the educational process, providing new practices in teaching and learning, making it increasingly affordable, pleasant and attractive for both students and for teachers. An example is the development of learning objects (OA). This research project aims to develop a learning object to work teaching chemistry in high school with the theme "Junk". For this development it is necessary to make a historical survey of education in Brazil, as well as identifying the use of media technology in education, bringing important benefits in the process of teaching and learning, stimulating students to seek more and more knowledge and thus make the education increasingly interactive and interesting for students.
