From Raw to Processed: The Science Explained

Section role: supports the formal explanation section while the teacher consolidates the hands-on findings from the previous investigation and corrects misconceptions. Slides: (1) Title - 'From Raw to Processed: The Science Explained'; (2) Properties of Metals - bullets: luster, malleability, and ductility with examples from the copper wire and iron nail; (3) The Magnetism Misconception - bullets: clarifying that only items with iron, nickel, or cobalt are magnetic; (4) The Chemistry of Rust - bullets: formula Iron + Water + Oxygen -> Rust (Iron Oxide), connecting back to Nail A and Nail B; (5) Non-metals Defined - bullets: coal and chalk as dull, brittle insulators; (6) The Processing Cycle - bullets: transforming sand to glass, clay to ceramic in a kiln, and plant fibers through weaving. Closing slide: 'How does processing change a weak raw material into something strong and useful?' - hands control back to the teacher for the mastery check.
