                                                        ABSTRACT


            The  paper  assessed  the  Green  Chemistry  laboratory  manual  prepared  by  the  researcher,  which
            integrated the five out of the twelve Green Chemistry principles. These principles include the prevention of
            waste, design for safer chemical use, design for degradation, design for energy efficiency, and design for
            inherently  safer  chemicals  for  accident  prevention.  The  experimental  group  incorporated  these  five
            principles  into  its  eight  laboratory  experiments  and  activities.  The  control  group  experienced  regular
            teaching and flipped classroom intervention. The analysis of the cost of materials and manual evaluation
            were  conducted  to  prove  that  integration  has  been  achieved.  Results  showed  no  significant  difference
            between the experimental and control groups’ academic achievement. Both have attained the same level of
            proficiency, so the range of conceptual learning is also the same. Even so, the experimental group has the
            advantages of a more sustainable approach in their science laboratory. In the Green Chemistry laboratory,
            materials  can  be  found  in  every  household,  reagents  are  non-hazardous,  and  heating  sources  are  more
            energy  efficient.  The  students  realized  the  significance  of  the  integration  in  the  science  laboratory  and
            real-life applications. Students also developed their environmental awareness. The accompanying laboratory
            manual emphasizing the principles of Green Chemistry has been well received by teachers and students.
            Cost analysis showed that the materials in the Green Chemistry laboratory cost lesser than those used in a
            conventional  laboratory.  Other  schools  lacking  the  conventional  laboratory  facilities  can  adopt  a  Green
            Chemistry laboratory, which offers more sustainable methods and resources to provide for the experiments
            and activities.
