Vibration and Sound Experiment

I recently conducted a lesson on Vibration and Sound with my class.  The students were asked to use a ruler and decide how to make a low pitch and high pitch.  At first my students thought that flicking the ruler in different ways would cause the pitch to change.  They soon found that they had to move the ruler using different lengths that hang off of the table to produce the different pitches.  They then used this knowledge to play "Twinkle, Twinkle Little Star" with their ruler.  It was a very fun and educational experiment.  My students were engaged and exited during the entire experiment.  The only struggle that my students had was getting started on their song.  I think next time I will get them started with the first two notes so that do not get as frustrated and confused in the beginning.  Here are some of their data sheets that they completed during the lesson.

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....
