Integrated science is a course with merged topics like biology, chemistry, physics, etc. According to Gallagher et al (2008) defined integrated science as a cumulative approach of scientific study
that synthesizes the perspectives of the individual disciplines and integrates them during all phases of the approach to a question or problem, with the results having an influence on policy and management decision.
Integrated science according to Oladimeji in Ene (2009) is defined as amalgamated course designed to show the unit, wholeness and interrelationship of the distinct disciplines of biology, chemistry, physics and so forth, should not be discernible. It is the virtue of its name of bringing together of different branches of science as a unified whole through the concepts and methods which pervade the natural science.
