This lesson is an activity where students make a model "landline" and investigate how sound travels.
1-PS4-4 Use tools and materials to design and build a device that uses light or sound to solve the problem of communicating over a distance. Clarification Statement: Examples of devices could include a light source to send signals, paper cup and string “telephones,” and a pattern of drum beats. Assessment Boundary: Assessment does not include technological details for how communication devices work.
This resource is explicitly designed to build towards this performance expectation.
Comments about Including the Performance Expectation Paper cups are used for this investigation but plastic or styrofoam cups could also be used to predict, describe, and compare the sound made.
This resource is explicitly designed to build towards this science and engineering practice.
Comments about Including the Science and Engineering Practice By developing the cup phones, the students solve the problem of how to communicate over a long distance. Students could modify their originally created cup phones and use longer or shorter string to see if the sound would be changed across scenarios with contrasting materials and distances.
This resource is explicitly designed to build towards this disciplinary core idea.
Comments about Including the Disciplinary Core Idea Have students attempt making different sounds other than their voices through the cups. They could clap their hands, snap their fingers, whistle, etc.
This resource is explicitly designed to build towards this crosscutting concept.
Comments about Including the Crosscutting Concept Students could investigate different materials for the cups and string to make the phones and collect and keep data about which design solution is best to use for communicating over a long distance. The data should be shared with the whole class.
