Helps students unravel the marvels of science and discern its applications and implications to modern society!

The third edition substantially integrates additional topics and timely issues with the basic principles of the different branches of science.

  • Integrated Science systematically presents basic discussions of matter, motion, force, work, and energy. It highlights the importance of recycling and conservation of natural resources.
  • Biology accompanies students in their bid toward a more meaningful understanding of the science of life. The inclusion of issues with moral and social implications intends to encourage lively discourses in class.
  • Chemistry probes into the nature of matter and the problem of pollution. It includes a new chapter on molecular mechanisms underlying biological complexity.
  • Physics extends beyond the fundamentals of matter and energy. It also discusses radio and television communication, noise pollution, and basic electronics.

The Textbook follows the minimum learning competencies prescribed by DepEd. It also answers the universal call for environmental awareness.

The Laboratory Manual supplements the knowledge acquired from the textbook; puts into practice the scientific methods; imbues scientific attitudes in the students; and serves as gauge of students’ comprehension of the scientific principles taught.

The Teachers Guide presents clear- cut objectives and background information which may prove very useful to all science teachers. It emphasizes the need to inject values in each lesson.
