How Sound Works: Weekly Blog #17

Summary 

This week in science, I learned about how sound functions. Sound is a vibration of molecules, in other words, a motion that can transmit energy through matter. that has different elements that contribute to how it sounds.  The first think I am going to talk about is pitch. Pitch is how essentially just how high or low a sound is, but depends on the frequency of the sound. A sound frequency is how fast or slow a sound is. The amplitude of a sound is how loud a sound can get or the maximum extent of a vibration. How loud a sound is measured in DB or decibels that can also be expressed as the amplitude. Because sound is measured in waves, there are many different wavelengths present in the vibrations. depending on how close the vibrations are depends on how high the pitch will be. This is what I learned this week in science

S&EP - Using models

This week in science, there was a heavy use of models to help us understand how sound interact with the different environments and situations surrounding it. The first experiment that I am going to talk about is the tuning fork and water experiment. Through this experiment, I was able to see the different effects that sound waves vibrations can have on water. I saw that the vibrations that come off of sound waves were clearly present because it made splashes in the water and also was a able to make the ping pong ball (second part of the experiment) bounce on impact.We also did a different experiment where we tried blowing on different bottle and depending on how much water there was in each one changed the pitch of the sound.

XCC - Structure and Function

There was a great factor of structure and function that I noticed when studying sound this week.In order for us to hear sound, there is a series of events that occur before that can happen. Our ears are structured in a certain way that allows us to process sounds, and each part serves a different function. When there is sound, there is a vibration of molecules in the air. Those vibrations reach our eardrums and makes our eardrum vibrate. Then, the little hairs lined across the eardrum send signals to your brain, and that's what makes you perceive sound as. This is related to structure and function because without all the little components of your ear being structured the way they ware, we would not be able to hear sound the was that we do.
