the current research aimed to evaluate the content of the preparatory stage science books in The Egyptian Arabic Republic on the subject of chemical reactions in the light of The Next Generation Science Standards" NGSS ", in order to determine the level of inclusion of the basic dimensions of these standards in content of these books which are: (Science and Engineering Practices-Disciplinary Core Idea - Crosscutting Concepts). The current research is based on the calculation of the frequencies, percentages and their averages of include the standards and indicators of each dimension in the content of the science books of sample of the research ,which were represented in the first grade book " energy unit " & "matter and its construction unit " first term, and " chemical reactions unit " second term. And the second grade book "Periodicity of elements and their properties unit " first term. And The third grade book "Chemical reactions unit " second term for the year of 2018/2019. The current research used a descriptive analytical research method in the content analysis of the chemical reactions units of sample of the research. The data collection and analysis were based on the content analysis tool, which was prepared in the light of The Next Generation Science Standards" NGSS " for chemical reactions, which is consisting of 3 axes, 10 standards and 18 indicators. The results found that all axes of the standards achieved inclusion percentages average of 33.3%, which is the low inclusion level ,which requires development in the light of NGSS. The " Disciplinary Core Idea" axis achieved the highest inclusion percentages average "57.7%", which is "medium" inclusion level, followed by the " Science and Engineering Practices " axis 35.2%, which is "low" inclusion level, followed by the " Crosscutting Concepts " axis " 7.1% ", Which is a" very low "inclusion level, As appeared a variation in the inclusion percentages of standards and indicators for each axis. Also The first grade science books achieved the highest inclusion percentages average "46.6%", which is "low" inclusion level, followed by the third grade science books "29.8%", which is "low" inclusion level, followed by the second grade science books " 23.6% which is " very low" inclusion level. The current research also suggested some chemical reactions lesson plans in the light of the NGSS standards. in the light of these results The research reached to recommendations and suggestions for generalizing the results of the research.
