Studying how potato chips are made turns food engineering into an engaging design and technology case study for middle and high school STEM. A focused reading passage with questions can help students learn about potato selection, washing, slicing, blanching, frying, de oiler removal, seasoning, metal detection, and nitrogen flush packaging. Learners could connect chemistry and materials science by analyzing moisture, water activity, oil uptake, Maillard browning, texture, color, and thickness un
