This term we are studying about sound. we have been doing experiment with 2 cups and 3 types of string but you would need to have two plastic cups so you could poke a hole in the two cups and stick your string in both of the cups . “why do you have strings and two cups” ? well we are learning how sound travels through the string and end up going to the other cup which your friend or your family would have next to her or his ear so they could hear what you're saying .
Sound is a form of energy that travels through sound waves. Sound waves is not the beach wave it from how you hit something or somethings it viarte. Sound Is really fast and goes at different speeds. sound is caused when material or an object is hit after it been hit it vibrates and it travails to your eardrums and to your brain then your brain will say I recognise that sound.
millions of different sounds can be made. sounds can be as quiet as a whisper, or as loud as a speeding train.” what exactly is sound”?. Sound is created when something vibrates in a particular way. if you hit a drum, you can hear the sound the vibration makes. you can also see the sound the vibration makes.
