Abstract
The research aims to determine the science teachers' knowledge level in elementary schools about the engineering design concept. It determines the application level of engineering design among the science teachers at the elementary level in teaching science and highlights the obstacles faced in implementing these. The descriptive survey method was used to achieve the research aim by applying a questionnaire to a sample of 97 science teachers in primary schools in Riyadh city. The research was limited to the concepts of engineering design and engineering practices as mentioned in the next generation of NGSS science standards. It was found that science teachers were unaware of the importance of developing engineering design skills among students. It might be due to ineffective teachers' training in engineering design skills development. It is strongly suggested to educate supervisors about the importance of directing male and female teachers to apply engineering design in science teaching for the elementary stage. It is essential to provide appropriate educational laboratories and means for employing engineering design and teaching science for the elementary stage.
