This is a simple investigation of the Cup-A-Phone! This investigation directly aligns with NGSS Standards 1-PS4-1 and 1-PS4-4 by teaching students how sounds waves travel so that we can hear each other, and how we can make devices to help us communicate over distances. This activity requires students to participate in cooperative learning, by giving each group member a specific job for each investigation.
In the investigation, students create different varieties of cup-a-phones and determine which variables worked well and which worked poorly. Included in this bundle is an editable Investigation Journal, and an interactive, editable Investigation PowerPoint Presentation.
