The study aimed to explore the extent of inclusion of next generation science standards, NGSS in 6th, 7th, and 8th grades science textbooks in the energy unit (ed. 2016/2017). The study used a descriptive approach through content analysis of these science textbooks. The study sample consisted of all lessons included in energy unit, which are taught in all of the three grades during the academic year 2016. Content analysis tool was designed in the light of NGSS. It contained four major standards, which were divided into five indicators. Data were collected by using a 3-point Likert scale, namely: highly available, moderately available, and unavailable. Results of the study showed that the inclusion of all standards and their indicators for scientific and engineering practices in all grades were low and/or unavailable, with exception to "planning and survey" standard in 6thgrade science textbook, where its percentage was (52.17%), which, on the other hand, decreased in 8th grade science textbook to reach (33.3%), where as "planning and using models" standard percentage was (33.3%). Additionally, findings of the study indicated that the least inclusion standard was "clarification and designing solutions" standard with percentage of (4.34%) in 6th grade science textbook and (7.41%) 8th grade science textbook. Results also revealed that there was a deficiency regarding the scope and sequence matrix of NGSS in energy unit content knowledge, where these standards were not included in 7thgrade science textbook. Finally, recommendations and further research suggestions were proposed. (Published Abstract)
