Grade 10 Science 2018 Exam
This document provides instructions and reference materials for a written examination in Applied Science and Technology. It begins with multiple choice questions about topics like oxidation, gravitational force, electric circuits, and friction. This is followed by constructed response questions to be answered in the student booklet. The final section involves analyzing a clock to understand its mechanical, electrical components, and maintenance requirements. Formulas and quantities for applied science and technology are provided as a reference document. Students are instructed to use the question booklet, student booklet, reference document, and answer sheet to complete the exam within the allotted 3 hours.
