the purpose of the study was to build a proposed unit in the light of the standards of life applications of chemistry formulated by the (4MAT) model of McCarthy for second year secondary school students to measure its impact on the development of their attitude towards the study of chemistry. To achieve this, a list of standards of life applications of the content of chemistry curriculum at the secondary school level was prepared  The “Industrial Chemistry" unit was prepared in the light of the list of standards formulated according to the McCarthy (4MAT) model. Instrument of the study is the scale of the attitudes towards studying chemistry. Participants (27 girls) were selected from 2nd year secondary school students in Beni Mazar, The semi-experimental one-group design was used to measure the effect of the independent variable "Industrial Chemistry" Unit in the light of the standards of life applications of the chemistry curriculum formulated according to the McCarthy (4MAT) model on the attitudes towards the study of chemistry. The results of the study indicated that there was a statistically significant difference between the mean scores of the participants in the pre-post application in favor of post-application of the scale of the attitudes towards studying chemistry.
