Hey Bloggers! This week in literacy I have been reading about sound and had to write a short report on it. so here it is! :)
Sound
Today we will be looking about how sound works, I have four questions about sound, which are going to help us understand. I will be answering these four questions; What is sound? How does sound travel? Does sound work in space? Why does sound at different speeds through different materials?
What is sound? Sound is the energy things produce when they vibrate, for example, if you were to clap. Your hands would vibrate at very high speed (usually so fast, you can’t see them vibrating) The vibrations are very strong, causing the air to vibrate, so the vibrations go all through the air, eventually causing the air in your ears to vibrate, and that’s when you can hear the sound of the clap.
How does sound travel? In someway, the sound is a lot like light, Sound travels from some source, just like light, (it would come from the sun or even a lightbulb), It’s very fast and needs something to travel through/bounce off of, so it won’t work in places with no air, gas, or anything, (like I explain in the next paragraph).
In the article, I learned that sound is like light, it needs something to travel through or bounce off of, this can be things like air, water, glass, or metal. After reading this I wondered if you could hear anything in space because there is no air or gas or anything for sound to travel through. So, can you hear in space? The answer is no, in 1660 Robert Boyle did an experiment testing if we could hear anything if we put a clock in a jar and sucked all the air out. It was proved that we could not hear anything, because there was nothing for the sound to travel through, so in space with no gas or air, you would not be able to hear anything.
Another question I formed while reading the article was, Why does sound at different speeds through different materials? Sound can travel through more solid materials because the molecules are closer together, making it easier to bounce off of solid objects, so when the vibrations bounce off a solid material, the vibrations are stronger and move faster.
I reckon sound is very interesting, and by looking at these questions I feel like I have a better understanding of sound, and I hope you do too.

Hi, Greer
ReplyDeleteYour report is really good and is easy to read for people that don't have any idea of how sound works. Just make sure you check what you have wrote because in the 3rd paragraph you added somethings you have already said. Overall your review is really good and easy to understand. Good job!
