Media queries in Sass

I am wondering if there is a way to write media queries in sass, so I can give a certain style between let's say: 300px to 900px

in css it looks like this

@media only screen and (min-width: 300px) and (max-width: 900px){

}

I know I can write

@media (max-width: 900px)

in sass but how to make that range?

$small: 300px;
$medium: 900px;

.smth {
  //some CSS
  @media screen and (max-width: $small) {
    //do Smth
  }
  @media screen and (min-width: $medium) {
    //do Smth
  }
}

Something like this?
