The aim of the research is to identify the effectiveness of teaching scientific concepts with the standards of the ISEF Intel model for the fifth grade students in Jeddah in order to find out the extent to which science curricula in the primary stage according to the nation's vision provide students with 21st century skills, in particular scientific research skills. The semi-experimental design of two groups (experimental and control groups) was chosen using pre- and post-tests according to the standards of the Intel ISEF competition. The students of the experimental group (30 students) studied the developed unit of environmental systems using the teacher's guide in the light of stem to develop the research skills according to the standards of intel ISEF, while the students of the control group (30 students) studied the unit with the usual teaching methods. The results showed the following: 1) there were statistically significant differences at (α≥0.05) between the average scores of the experimental group and the control group in the post-application used to test the skills of research according to the standards of the Intel ISEF competition, in favor of the experimental group. 2) The magnitude of the impact according to the equation of the eta square was (0.75), which refers to the significant effectiveness of the stem approach in the development of scientific research skills in the light of standards of the Intel ISEF competition for the fifth grade students in Jeddah who studied the unit of environmental systems according to stem. 3) There were no statistically significant differences at (α≥0.05) between the average of improvement rate in the scientific research skills of the experimental group students with different skill levels (high, middle, low), indicating the effectiveness of studying the ecosystem unit through the stem approach in the development of scientific research skills in the light of Intel ISEF standards for students with varying skill levels. Based on the results of the research, it was recommended that the use of the stem education approach should be generalized in the teaching of science curricula, because it is effective in developing the students' thinking and research skills. It was also recommended that the importance of creating the educational environment should be emphasized by providing the basic infrastructure for education, with using the stem approach to teach science. Moreover, the results of the study revealed the necessity of training students in all stages on the methods of international competitions testing (ISEF) in which students from Saudi Arabia participate.
