Luca drinks coffee with milk every morning. He notices that some mornings his coffee seems to cool down quickly and some mornings it seems to stay warm longer. He wonders what
factors affect how quickly his coffee cools down. So, he decides to design an experiment. He
has the following supplies available:
• two small coffee mugs
• two large coffee mugs
• hot caffeinated coffee
• a pot
• a stove
• cold milk
• a thermometer
Using only these supplies, which two questions can Luca investigate with an experiment?
