How Loud is Too Loud: Introducing Logarithms through Sound
When introducing logarithms we look at how decibels levels around us impact our environment and how we live. Students use the following template, a whistle, and the Decibel X app from the App Store.
Students record how loud a whistle is from various spots on a football field and record the decibel readings from the app. Students record the data, plot points, and answer the questions in the Numbers app and then we share out large group about what is going on in our graph.
Here is some example data that a student collected.
