Insulation and Heat Transfer Experiment

Joseph conducts an insulation experiment from Lesson 7 of the 'Energy' science unit. The experiment involves wrapping water bottles with different materials: aluminum foil, garbage bag, newspaper, and a wool sock. After filling the bottles with hot water, initial temperatures are recorded. After 15 minutes, temperatures are checked again to determine which material is the best insulator. The garbage bag proves to be the most effective insulator, losing the least heat.
