The study uses content analysis method through a prepared tool. After confirming its validity and reliability, 174 activities of upgraded science textbooks were analyzed in terms of four levels of inquiry: confirmatory inquiry, structured inquiry, guided inquiry and open inquiry. The findings of the study show that the structured inquiry has the larger proportion of activities in science textbooks, while open inquiry does not show in intermediate and secondary grades upgraded science textbooks. The findings also show that second intermediate grade science textbooks and second secondary grade biology textbooks are the best guides to constructive inquiry in the science textbooks activities. Moreover, the findings reveal that there is a statistically significant relationship between the levels of inquiry and the internal distribution of the activities of intermediate and secondary grade science textbooks.
