The Harried Cup of Coffee June 15, 2009 Purpose In this experiment, students will devise an experiment to test a hypothesis. In addition, they will incorporate the scientific method in the design and execution of the experiment [method on keeping coffee hottest], and familiarize themselves with various measuring apparatuses. Hypothesis To keep the cup of coffee as hot as possible, one should add the cream halfway between the 10-minute mark. This is because the ceramic mug should keep the coffee hot enough for at least the 5-minute mark; after that, adding the cool cream should slow the cooling rate by decreasing the difference in temperature between the hot coffee and its surroundings. Materials -hot water -styrofoam cup -spoon -crushed ice -paper cup -triple beam balance -hot plate -thermometer -watch -graduated cylinder -500 mL beaker Procedure 1) A 500 mL beaker was obtained to serve as a “cup” for the coffee. The beaker was filled with water, serving as “coffee” in this experiment. 2)
