This document contains a 30-mark multiple choice section and a 20-mark short answer section about investigating materials. The multiple choice section contains 30 questions about classifying objects based on their material, identifying materials' properties, and understanding recycling processes. The short answer section contains 4 questions about analyzing experiments investigating different materials' properties and the benefits of recycling and reusing materials.
