Teaching Approach:
The Grade 8 science curriculum emphasizes hands-on experiments, group discussions, and interactive learning to make science engaging and practical. Students are encouraged to participate in science projects, quizzes, and exhibitions to enhance their understanding of scientific concepts.
Assessment:
Students are evaluated through written examinations, practical tests, and project assignments. Assessments focus on both theoretical knowledge and practical application of concepts.
By the end of Grade 8, students are expected to have a solid foundation in science, preparing them for more advanced studies in higher grades.
