Instructional Materials
This resource, vetted by NSTA curators, is provided to teachers along with suggested modifications to make it more in line with the vision of the NGSS. While not considered to be "fully aligned," the resources and expert recommendations provide teachers with concrete examples and expert guidance using the EQuIP rubric to adapted existing resources.

Performance Expectations

1-PS4-1 Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate.

Clarification Statement: Examples of vibrating materials that make sound could include tuning forks and plucking a stretched string. Examples of how sound can make matter vibrate could include holding a piece of paper near a speaker making sound and holding an object near a vibrating tuning fork.

Assessment Boundary: none

This resource is explicitly designed to build towards this performance expectation.

Comments about Including the Performance Expectation
This video can be used as the anchoring event for a series of lessons around 1-PS4-1. After watching this anchoring event, students might model how they think the phenomenon works, ask questions, and design investigations which lead to the discovery of the ideas for this Performance Expectation. For safety reasons, any modeling of this phenomenon would need to be paper and pencil!

Science and Engineering Practices

This resource appears to be designed to build towards this science and engineering practice, though the resource developer has not explicitly stated so.

Comments about Including the Science and Engineering Practice
As an anchoring event, this phenomenon provides a curious situation that will spark student questions. These questions will center around the phenomenon of sound, leading to investigations demanding more information about the nature of sound.

Disciplinary Core Ideas

This resource appears to be designed to build towards this disciplinary core idea, though the resource developer has not explicitly stated so.

Comments about Including the Disciplinary Core Idea
To effectively use this phenomenon as the anchoring event for a set of lessons around this PE, students should model each aspect of the phenomenon (the sound source and the glass). They will then need experiences working with materials that both make sound (i.e. instruments) and those that detect sounds (i.e. a balloon). These will help students to build the requisite understanding with the anchoring event as a contextual reference.

Crosscutting Concepts

This resource was not designed to build towards this crosscutting concept, but can be used to build towards it using the suggestions provided below.

Comments about Including the Crosscutting Concept
After experiencing this phenomenon, students will identify the cause and effect relationship (the voice breaks the glass). After modeling this, they will then need to work together to brainstorm ways to investigate the components of their model identified in the cause and effect relationship.
