I have added the media query:
@media screen and (min-width: 480px) {
}
/************************************** TWO COLUMN LAYOUT ***************************************/
#primary { width: 50%; float: left; }
#secondary { width: 40%; float: right; }
However, when I make window smaller, the "Contact" page stays in 2 columns instead of going to 1 column for mobile.

You made a very simple mistake :)
you have put a condition that a code should execute if the condition of the media query is met (i.e minimum width of 480px) but when u put this condition only the code inside the curly brackets { //code goes here } will get executed
summary : put the code inside { } @media screen and (min-width: 480px) { // code here }
note : its actually a basic programming concept that when you write a condition and its true the code inside the curly bracketwill execute :)

You should put the code below the media query inside it. Then you should make the primary and secondary elements have a width of 90% and display:block; as their display property
