In this activity, students will collect data as a heated temperature sensor cools for three minutes, graph the cooling curve, and determine a model to fit the temperature versus time data.   

• Horizontal Asymptote
• Vertical Translation
• Exponential function

A hot drink gradually cools off but how can the cooling process be described? In this activity, students will collect data as a heated temperature sensor cools for three minutes, graph the cooling curve, and determine a model to fit the temperature versus time data.  

Students will:

• Collect temperature versus time data of a cooling object and graph a scatter plot.
• Model the temperature versus time data with an exponential equation in the form y = a(b)^x + c.
