Learn about changing sounds and music as you experiment with different musical instruments in this fun, interactive activity. Plucking strings of different lengths results in a variety of sounds, some can be high pitched while others can be very low pitched. Play common instruments such as drums and the guitar while also trying a bottle, an instrument that definitely isn’t so common. Experiment with different settings and sort your results into a pitch and loudness grid. Listen to the noise as you blow on a bottle and then see what happens when you try again after filling it with water. Bang on a drum and listen to the change in pitch as you tighten the drum skin. Kids will enjoy the challenges of this cool science game.
