The aim of the current research is to identify the effectiveness of the Suchman model in acquiring chemical concepts among the fifth grade scientific level students, and to verify the goal of the research, the following null hypothesis was formulated - There is no statistically significant difference at the level of ( 0.05 ) between the average scores of the experimental group students who studied according to the Suchman model and the average scores of the control group students who studied according to the normal method in the concept acquisition test. The current research community was represented by the fifth grade scientific level students in the secondary and preparatory schools for government girls affiliated with the Directorate of Karbala Education for the academic year 2021-2022 AD. By random selection, Al-Farouk Prep for girls was chosen from among the schools of the current research community, as it included three divisions ( A , B, C ). The two divisions ( A ) and ( C ) were chosen by simple randomization to represent ( C ) the experimental group of ( 35 ) students, which was studied according to the steps of the Suchman model, and similarly, from Division (A) to represent the control group, which was studied according to the usual method. The experimental design was adopted with two groups ( experimental and control ), which partially control one of the other two Of those with a post-test in acquiring chemical concepts, the experiment was applied in the first semester of the academic year 2021-2022 AD , and it lasted (11) weeks. The researcher herself studied the two research groups, chemistry for the fifth scientific level grade, and it was four sessions a week. The two research groups ( experimental and control ) were rewarded in a number of variables, including (the previous year's achievement level in chemistry , the previous information test, and intelligence ). The content of the current research was determined by three chapters of the chemistry book according to the omissions of the Iraqi Ministry of Education, if it was analyzed to conduct purposes, which reached (148) behavioral purposes in light of Bloom's classification of the knowledge field for the first six levels ( remember , understand, apply, analyze, compose, evaluate ), and prepare (44) daily teaching plans for the group The control according to the usual method of achieving the goal of the research, the researcher prepared an objective tool e represented by a concept test consisting of(42) concepts of the type of multiple choice, and the validity of the chemical concepts acquisition test tool and extracting its stability according to the Kueder Richardson equation -20 , as it reached (0.84 ), as well as the extraction of psychometric properties. After the completion of the experiment, the concept acquisition test was applied to the students of the two groups of the current research sample (experimental and control) and then processing the data statistically using the t-test for two independent samples equal in number. The results indicated the superiority of the experimental group students who studied according to the steps of the Suchman model over the students of the control group who studied using the usual method in the test of acquiring chemical concepts and with a large effect
