MD 9th Grade Science Curriculum
Give your 9th grader the support they need to keep up with Maryland science. Step-by-step lessons and practice problems cover every topic taught in class this year.
About 9th Grade Maryland science
Maryland follows the Maryland College Career Ready Standards for science, built around the Next Generation Science Standards framework. In 9th grade, students work across biology, chemistry, physics, and earth and environmental science - covering strands such as cell division, basic genetics and inheritance, chemical bonding and reactions, circuits, Earth systems, biogeochemical cycles, and human impact. StudyPug provides lessons, practice problems, and step-by-step explanations aligned to every strand so students can review concepts at their own pace.
- Strands: cell division, genetics, chemical bonding, reactions, circuits, Earth systems, biogeochemical cycles, and human impact
- Video lessons and step-by-step explanations for every 9th grade science topic
- Practice problems with guided solutions aligned to Maryland science standards
- Foundation review and challenge problems to support all skill levels

How StudyPug Helps MD 9th Grade Science Students
When a student gets stuck on a concept like chemical bonding or inheritance, StudyPug lets them go back to exactly that topic and watch a focused video lesson before working through practice problems with guided solutions. There is no need to wait for the next class or search through a textbook.
The foundation review strand helps students who need to close gaps from earlier grades, while the challenge zone pushes students who are ready to go further. Both sit inside the same course so no separate resource is needed.
