DE Science Elementary “5-Minute Prep” For Sound, Heat, and Light Sound Volume
Volume – The Big Ideas Sounds can be loud or soft. The amount of energy in a sound wave determines the volume of the sound. Sounds with high-energy vibrations are loud. Sounds with low-energy vibrations are soft.
Volume – Prior Knowledge Students have been interacting with and fascinated by sounds since birth. It will help for students to use the Fun-damental, Sound, Heat, and Light, to review sound. It will be helpful if students have:Sound, Heat, and Light listened to different types of music at varying volumes. played with different toys that make sounds at different volumes.
Volume – Common Misconceptions Loudness and pitch of sounds are the same things. –Reality: Volume, which is the amount of energy in a sound wave, refers to the loudness of a sound. Pitch is determined by the frequency of vibration. Hitting an object harder changes the pitch of the sound produced. –Reality: Hitting an object harder increase the amount of energy and therefore increases the volume and not the pitch.
Volume – Using DE Science Content When you close this presentation, you can review the following recommended resources for Volume. Exploration: VolumeVolume Reading Passage: LigyrophobiaLigyrophobia Video: VolumeVolume Video: How is Sound Made?How is Sound Made? Use the PowerPoint version of this presentation for hyperlinks to these resources or you can get to them through the browser or search feature.
Volume – Instructional Ideas Invite the instrumental teacher and a few students to play a song for the class that has varying volumes particularly a song with solos or duets in it. –Have students listen carefully and record how many times the volume changes in the song. This should correspond with the number of instruments playing or the changing of the volume between the whole ensemble and any solos or duets.
Volume – Instructional Ideas After reading Ligyrophobia, have each student write a paragraph about a time when they were frightened by a loud sound. Ligyrophobia –Students should include scientific information about the sound similar to what is presented in the reading passage.
