Angle of Elevation with iPhone's Siri

You can ask Siri on an iPhone “What planes are flying over me?” and she will tell you exactly that. But exactly how far out of a radius does Siri report planes? This activity will help you and your students use trigonometry and angles of elevation and depression find out! Applications include the use of tangent AND cosine!

There are several versions of this activity all in one download! The first version is a printable activity where the data is provided and a map is provided. The second activity is a template for students to enter data that they have collected using their own Siri data that is relevant to where they live. (I had students who have iPhones ask Siri the question, and then email me screenshots of what they found. I then shared the screenshots with the class via a projector or handout.) There is also space provided for students to find a map of where they live and use that to plot the planes’ distances. The third activity is an extension activity that uses international data, and can be used in conjunction with the versions mentioned above. Also provided in this download is an Excel file to generate your own answer key for use with the version where students collect their own data.

Common Core Standards: HSG-SRT.C.6, HSG-SRT.C.8
