Thursday 26th March 2020 – Reading Comprehension

Morning Year 4, I hope you are enjoying the tasks. Here is some reading comprehension.

 

Sound Waves
Sound is all around us .We can hear a bird in a tree, your mum shouting upstairs, “Hurry up – we’re late!” and we can listen to our favourite songs and music.
These are all different types of sounds but they have one thing in common….They all travel to your ear as sound waves.
Catching the wave:

Sound waves are vibrations (little wobbles) that move the air, in the same way that wind moves the water in the sea to make waves. The waves travel towards your ear as the air particles move the next door particles until they arrive at your ear.
How do the sound waves know how to get to your ear? Well, the answer is, they don’t….. The sound waves travel in lots of different directions from where the sound is made and your ear catches the bit that comes in your direction. Once the ear has ‘caught’ the sound, it carries on vibrating the tiny bones inside your ear which turn the vibrations into electric pulses that are sent to the brain.
Pitch
The pitch of a sound is how high or low it sounds. This depends on how quickly the source of the sound vibrates. This is called the frequency of the sound and this is measured in hertz (Hz).The faster the vibration, the higher the frequency and the higher the pitch of the note. A low note will have a slow vibration and a lower frequency. You can make a string on an instrument have a higher frequency by shortening the string or making it tighter.
Volume
Volume is how loud a sound is, no matter how high or low the pitch of the note. It is measured
in decibels (Db). The volume is how hard the particles in the air are hitting each other, a bit like how hard you hit a rounders ball. So to make a guitar string louder, but the same pitch, you pluck it with more force.

 

Please can you answer in full sentences:

1. What vibrates inside your ear to send the sound signals into your body?
2. What is another name for the stirrup bone inside your ear?
3. What is the speed of sound in air?
4. Why has the author put (little wobbles) in brackets next to the word ‘vibrations’ in the first sentence?
5. Sound needs air or other particles to move for it to work. In space there is a vacuum and no particles……. Do you think we can hear sound in space?
6. Thinking about noise levels, what safety kit does a Formula One driver need?
