CURRICULUM GUIDE
About the Ontario Science Curriculum
How The Ontario Curriculum Works
The Ontario Curriculum sets science expectations by grade, organized into strands that cover life systems, matter, energy, and earth science.
How Ontario Differs
Ontario introduces structured strand-based science from Kindergarten and requires a full integrated science course in both Grade 9 and Grade 10 before subject specialization.
How Ontario Science Progresses
Students move from hands-on inquiry in the early grades through structured middle school strands, into Grade 9 and Grade 10 integrated science.
How Ontario Assesses Science
Ontario assesses science through provincial assessments, with EQAO testing at Grades 3, 6, and 9, and the OSSLT at Grade 10 for language alongside science.
