1-PS4-1. Demonstrate that vibrating materials can make sound and that sound can make materials vibrate. Clarification Statements:

• Examples of vibrating materials that make sound could include tuning forks, a stretched string or rubber band, and a drum head.
• Examples of how sound can make materials vibrate could include holding a piece of paper near a speaker making sound and holding an object near a vibrating tuning fork

This will be explained through our guiding question – how hummingbirds can make noise – and explore what causes sound. Students will learn that sound is caused by a vibration through experimentation and making musical instruments. They will watch rubber bands vibrate on cups and then make kazoos. They will then explore how sound travels by listening to each other speak through a cup and string telephone, and then putting their ears to the desk and scratching.
