Vibration

This week I was asked to produce an Inquiry based lesson plan.  I decided to center this lesson on vibration and pitch.  In this lesson students are given a ruler and asked to decide how to get different pitches of sound using the ruler and table.  Then they will use this new knowledge to play "Twinkle, Twinkle Little Star" using their ruler.  I can not wait to perform this lesson in class.  I really think that my second graders will love it.  I will let you know how this lesson plan lays out.  Hopefully it will go as well I think....
