Abstract: This paper studies the effect of telling a story while teaching the lesson “Photosynthesis” for students in grade 4 at Safir High School. The study shows how stories increase cognitive development, and that the positive words give you what you expect. Two groups of grade 4 (sections A and B) were taught in two different ways and examined after being learned. The resulting cases ensure the effect of the story while explaining the lesson. The students who had the story strategy 59% took above average (4.5) while the other group 19 % took above average.
