ON Science 9

ON Science 9 is the all‑in‑one Grade 9 science textbook designed for today’s Ontario classrooms. Clear explanations, vivid visuals, and hands‑on investigations guide learners through four big ideas of Grade 9 science:

• Sustainable Ecosystems — nutrient cycles, biodiversity, human impacts, and ecosystem services.
• Atoms, Elements, and Compounds — physical/chemical properties, atomic structure, the periodic table, and ionic & molecular compounds.
• The Study of the Universe — the night sky, the Sun and stars, galaxies, and modern space exploration.
• The Characteristics of Electricity — static electricity, circuits, resistance, series/parallel design, and efficient energy use.

Each chapter includes skill toolkits, real‑world “Science at Work” features, projects, chapter summaries, and reviews to build understanding and prepare students for assessment. Appendices provide math and study skills, star maps, chemistry references, a glossary, index, and a periodic table—everything learners and teachers need in one resource.

Perfect for classroom instruction, independent study, or homework support, ON Science 9 helps students connect scientific concepts to everyday life while developing the inquiry, data, and problem‑solving skills that power success in STEM.
