In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night. Learners log the call signs, locations, and quality of the transmissions on a data table. This resource includes information about how AM radio transmissions differ at day and night, the ionosphere, the history of call letters, and NOAA Weather Radio. Note: this activity must be completed during the evening or early in the morning before sunrise and learners must have access to an AM radio.
