Mississippi Science P.8.6.5
The Standard
- P.8.6
- Students will demonstrate an understanding of the properties, behaviors, and application of waves.
Conduct scientific investigations that describe the behavior of sound when resonance changes (e.g., waves in a stretched string and design of musical instruments).

What This Standard Means
What Students Need to Do
- Students change a string’s length or tension and record how its sound changes. They also test when a sound makes another object vibrate strongly.
What Mastery Looks Like
- Students change one factor at a time and record the pitch they hear or measure. They can explain that a shorter or tighter string usually has a higher pitch, and that an object responds most strongly to a matching frequency.
Common Misconceptions
- Students may confuse pitch with loudness and think plucking harder makes a higher note. They may expect any nearby object to vibrate strongly, even when its natural frequency does not match the sound.
How to Assess It
- Exit ticket: A rubber band is shortened and plucked. Predict how its pitch changes, then explain why a second band tuned to the new pitch vibrates more than one tuned to the old pitch.

Ways to Teach It
Hold a struck tuning fork over a plastic tube in water; raise the tube and mark the air length where the sound is loudest.
Ask students to write why one guitar string may vibrate when a nearby string is plucked at the same pitch.
Give pairs frequency cards labeled 220 Hz, 330 Hz, and 440 Hz; have them match sound sources to strings that would vibrate most strongly.
Turn a guitar tuning peg while students use a tuner app to record how the string’s pitch changes.
