Description How do we keep a gingerbread “cookie cabin” warm in winter? In this hands-on heat transfer lab, teams test everyday insulators (foil, felt, bubble wrap, cotton, foam, paper, etc.) to minimize thermal energy loss. Students design fair tests, collect temperature data over time, and iterate to improve their cabin’s insulation. ❄️🍪🔥 What students do 🛠️ Build a testable “cookie cabin” (small box or graham-cracker cabin—not for eating) with a thermometer port. 🔬 Plan a fair test:
