NC 9th Grade Science Curriculum
Give your child the support they need to keep up with North Carolina's 9th grade science curriculum, from genetics and chemical reactions to circuits and Earth systems.
About 9th Grade North Carolina science
North Carolina's 9th grade science follows the NC Standard Course of Study, covering life science, physical science, and Earth science strands. Students work through cell division, sexual reproduction, basic genetics and inheritance, elements, chemical bonding, reactions, solutions, circuits, the universe, Earth systems, and biogeochemical cycles. StudyPug provides step-by-step video lessons and practice problems for every strand, aligned to what NC classrooms are teaching.
- Strands: cell division and genetics, chemistry and reactions, circuits, Earth systems and biogeochemical cycles, and environmental and engineering applications
- Video lessons and step-by-step explanations for every topic
- Practice problems with instant feedback for every strand
- Fully aligned to the NC Standard Course of Study for 9th grade science

How StudyPug Helps NC 9th Grade Science Students
When a student gets stuck on a concept like chemical bonding or the nitrogen cycle, StudyPug provides short video lessons that break the topic into clear, numbered steps. Each lesson is followed by practice problems so students can confirm they understood before moving forward.
Parents and students can track progress across every strand in the NC 9th grade science course, making it easy to spot which topics need more attention before a class test or quiz.
Aligned to NC 9th Grade Science Curriculum
Every lesson and practice problem on StudyPug is built around the NC Standard Course of Study, ensuring that what your child studies on the platform matches exactly what their teacher covers in a North Carolina classroom.
