This week, Marvel Science Club explored the super science of sound waves.
First, we used sound pipe devices to hear how the air that moves through the ribbed areas inside the pipes makes different types of musical sounds. Surprisingly, we even heard all seven notes with different pitches.
For the next experiments we made devices to observe and hear how the air makes vibrating and buzzing sounds. The first device was a Buzz-Maker that we spun and twirled in the air. The pitch changes depending on the speed of the motion.
Our next sound apparatus was simply made from plastic straws. By cutting the flattened ends of the straws and then blowing into the Super Musical Straws, we heard air vibrations make music. The shorter the straw, the higher the frequency of the pitch. You can even say we played a trombone when two straws were used.
The final experiment was to create an amplifier and a phone using a plastic cup and a string. We “saw” how sounds can be made louder if a string is connected to a cup. And then we observed how a sound vibration can travel from one end of the room to another, even if you talk into a cup.
The Science of Sounds is a Superpower of all musicians or kids that love to create a buzz in a room! Check out our Facebook page for more photos.
