Recognize and describe the patterns and characteristics of a sound wave (amplitude, frequency).
Explain how the amplitude of a sound wave is related to its sound intensity (volume or loudness).
Measure sound intensities of sounds and draw graphs showing sound levels based on measured data.
Do you feel like it is always too loud in your classroom? In this lesson you can find out exactly how loud it is. Using Google's Science Journal, your students will measure and graph the sound levels in your classroom for different working scenarios. How loud are your students when doing independent work, having a group discussion, or listening to their teacher? Based on your students' data, you will determine as a class which sound levels are ideal for each scenario and create a classroom poster that reminds your students of these sound levels throughout the school year.
