Screaming is when you use your voice really loudly to make a sound that kind of sounds like a yell or a shout. It's like when you're playing and you get really excited and you scream because you're having so much fun!
When you scream, your voice gets louder because you're using your vocal cords and your lungs in a different way than when you talk normally. It's kind of like blowing up a balloon really big and then letting the air out really fast to make a loud noise.
Sometimes, people scream when they are scared or upset. This is because when we feel strong emotions like fear or anger, our bodies might react by making us feel like we need to make a loud noise to express how we're feeling.
It's important to remember that screaming too much or too loudly can actually hurt your voice and make it hard to talk normally later on. So, while screaming can be fun and helpful sometimes, it's also important to use your voice in a way that doesn't hurt it.
