Students use a temperature probe to collect data as the warmed probe cools. Students investigate Newton's law of cooling and model cooling data with an exponential function. They fit the data to a mathematical model after analysis.
After warming up an EasyTemp sensor, students let it cool.
The temperature values are corrected to show temperature change, and then students use a guess-and-test method to find a base e exponential model
Students then calculate an Exponential Regression that gives the model with a different base. The two models are compared.
