ABSTRACT
GANS (Gas in Nano Solid) is a state of matter formed in an alkaline medium due to the presence of
copper nanocoated with carbon and a zinc metal immerse in the alkaline solution. The copper and zinc are made
into a medium for attracting gas from the environment which will be chelated in the solution in a form of white
precipitate. Upon contamination to copper metal complex, the white precipitate will turn into different colors
depending on the presence of metal complex. Bringing GANS in the classroom would upskill the students ‘ pillars
of STEM namely: Science, Technology, Engineering and Mathematics. Hence, STEM-based approach was
among the pedagogies adapted today in the academe.
This study aimed to develop lesson plan on GANS production for classroom utilization in chemistry
teaching using STEM – based approach. The lesson plan underwent series of revision with a number of
consultations to STEM-Based approach experts. The said lesson plan was anchored on the stages of STEMbased lesson plan where social issues are addressed as a springboard in teaching chemistry, say, environmental
contaminants in this contexts. An activity is built in this lesson plan where strategy on how to produce GANS,
what colors of GANS are produce and what metals are to be used to obtain the desired GANS was
comprehensively illustrated. Further, what solution is required to obtain the desired GANS and the applications
of GANS were stressed in the activity for students.
Results of the activity showed that, white GANS was produce using zinc metal and nanocoated copper
metal immersed in an alkaline solution of sodium chloride. The production of GANS continue up until such
condition when a contamination of metal from copper exist. The white GANS will be seen as colors from light
blue to green appear which is an indication that there is a presence of complex metal in the GANS. The GANS is
energetic in nature as it was formed by the interaction of a certain condition that allowed precipitation in an
alkaline solution. It may be used as patch or made with health pen for muscular pain in humans body pain It can
also be used to energize potable water. It is recommended that a clinical trial for potential applications of this
GANS may be done by future researchers. The developed lesson plan was inter-rated by experts and classified it
as a potential instructional material. It is also recommended that the said lesson plan may be utilized by future
researchers in chemistry teaching to validate its efficacy.
