In Grade 8, learners expand science exploration and further their science literacy. They investigate density, solar energy, Earth’s internal structure, and homeostasis. The knowledge areas of matter, fields, energy, Earth science, and life science provide a foundation for study. An active and practical approach to learning and doing science continues in Grade 8. This includes conducting scientific investigations, furthering tool and measurement skills, exploring science in everyday life, and looking into how science interacts with society and the environment. Learners develop their agency and sense of belonging in science, and explore Indigenous ways of knowing, being, and doing, including through interacting with the local community and learning in nature. The Grades 7 to 9 band of the Nature of Science learning outcomes continues with an exploration of the purpose, method, application, and implications of science.
Inquiry questions to help guide learning and planning for the year may include the following:

Science learning outcomes are organized into five strands. These strands and learning outcomes are intended to be woven together throughout all learning experiences while supporting the development of global competencies. All strands equally and cohesively build scientific literacy, skills, and attitudes, inclusive of Indigenous ways and knowledge. Teachers can tailor curriculum implementation to the learners’ specific interests and needs.
