The sticks and straws harmonica doesn't get played quite the same way a real harmonica does, but through a series of experiments with the straws and the construction, students will see that the sound the harmonica makes is due to the vibration of a rubber band. How is sound used to measure wind over the ocean? 1. Blowing into (or inhaling from) a harmonica's different holes changes the sounds (notes) that are created. 2. The 2021 Build a Hydrophone version, currently available on DOSITS, is the most recent update to the hydrophone activity. This experiment is much like the pan flute above, but kids can alter the pitch by sliding the straws without reassembling the harmonica. For any other use, please contact Science Buddies. 2.

While noise pollution doesnt shred the ozone layer, it does inconvenience our neighbors (the furry ones as well as the ones in the neighboring homes). Place a straw piece under the rubber band, close to the edge on one end. By measuring the sound levels coming from several different sources, you can determine which would be the noisiest items to have in and around your yard and what places would be the noisiest to live. Next, shorten the string by placing a finger on the string. For another activity related to investigating decibel levels, see the Science With Your Smartphone : Decibel Meter activity.)

The scattering of sound from dissolved particles and bubbles is also demonstrated. This sound activity teaches children how varying levels of water in containers change the pitch of the sound created. After watching a demonstration (video available) of Ruben's Tube (a standing wave flame tube) that uses flame to visualize sound waves, students discuss noise levels and the decibel (dB) range of familiar sounds and environments, including the classroom. Changing the amount of the rubber band that vibrates also changes the "pitch" of the sound (because the rubber band vibrates faster or slower, which changes the frequency of the sound wave). This elementary sound science project shows kids how sound waves can travel through a string and be converted back to audible sound at the opposite end. Quiz 1: 5 questions Practice what you've learned, and level up on the above skills. Pulling the string or rubber band back farther created a larger vibration, thus a louder sound. The following instructions allow you to inexpensively build your own hydrophone. Sound as a Longitudinal Wave. Scissors or sharp knife to cut the bottle.

How is sound used to find objects on the ocean bottom? Ask your child to explain what happens to the sound the shorter a straw is cut, and create double pan flutes to make harmonies to further explore how length alters the pitch. Water travels faster through water than in the air, and animals that live underwater are able to hear sound clearly. This activity demonstrates how different variables affect the pitch of the sound produced by a cup made from a variety of materials.
