3rd Grade: Pitch

Third grade students found out if the pitch of the notes from the water glasses will go up or down when you take water out. We filled several mason jars with water at different water levels. We tapped the side of each glass bottle gently with a spoon. We recorded our data. After we recorded our data, students took turns playing the water glasses and having the class guess the tune they played a.k.a Name That Tune.
