1. DE Science Elementary “5-Minute Prep” For Sound, Heat, and Light Sound > Pitch

2. Pitch – The Big Ideas Sounds can have a low pitch or a high pitch. The frequency of vibration of a sound wave determines the pitch of the sound. Sounds with higher frequency have a higher pitch. Sounds with lower frequency have a lower pitch.

3. Pitch – 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 instruments that create different pitches.

4. Pitch – 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.

5. Pitch – Using DE Science Content When you close this presentation, you can review the following recommended resources for Pitch. Exploration: PitchPitch Reading Passage: Underwater SongsUnderwater Songs Video: PitchPitch Video: SoundSound Use the PowerPoint version of this presentation for hyperlinks to these resources or you can get to them through the browser or search feature.

6. Pitch – Instructional Ideas Invite the instrumental teacher and a few students to play a short song for the class. –Have each student listen for how many different pitches are being played by the instruments. –Have the students then complete the Exploration: Pitch to see the difference in sound waves.Pitch Create a science corner with a computer and various sound makers or instruments. –Allow students to explore the videos on sound and investigate how to make different pitches with the sound makers or instruments.
