Extensions: This activity connects science with music (sound waves).
Adaptations: Gifted students can adjust the musical notes that are created by adding more or less water to each glass or create a musical tune. Have ESL and Special Ed students give a thumbs up or down if sound is higher or lower in pitch and show why. Do this activity in small groups to help with learning.
