Lesson Plan
... Ask the students how they did identifying the sounds. Also, ask how they were able to tell what you were doing/using even though they had their eyes closed. Some questions to ask: o How was the sound created? (I created a vibration in the air molecules) o What kind of a wave is sound? (Mechanical). ...
