Studying how hot dogs are made turns food engineering into a practical design and technology case study for middle and high school STEM. A focused reading passage with questions supports students learning about meat selection, grinding, emulsification, seasoning with curing agents, vacuum stuffing, casing types, linking, cooking or smoking, chilling, peeling, and packaging. Learners could connect materials science and chemistry by examining fat protein emulsions, viscosity, water activity, therm
