Artifact Description

Students were asked to bring their favorite stuffed animal to class. In this initial model, students were prompted to (1) draw their “stuffie,” (2) write what types of sounds their stuffie might make if it were alive, and (3) draw arrows to show where the sound might come from. While rudimentary as “scientific models,” the task is intended to elicit a range of different sounds made by animals and to see initially how students think the sound is produced.

Student Thinking

Artifacts A, B, and C represent three different examples of stuffies and the sounds that they would make if they were alive: a dog (“ruff ruff ruff!”), a chicky (“chirp”), and a fish (“plop plop”). The arrows for all three point toward the mouth area of each animal.

Artifact D and E offer video explanations of initial models, which align very closely to what is seen in the drawn models.

The elicitation of various sounds that animals make (and that we can try to make!) will allow an opportunity to investigate how sounds differ and what might cause this difference. Each of these students identify the mouth as the place where the sound comes from, but they do not identify a mechanism by which the sound is produced (i.e. the vibration of some type of material).
