How to Down Load a Uchivida?

i bring my laps op into the class room and i use it to play vidios, either on you or down loaded from you. I can also show them pictures on the google image imash search. If there's a word that i can't explain, like if i'm trying to explain what a guinea pig is, donpe guinea pig,. Then then i will actually google image search the word guinea pig, pig - instantly they know what it is. And for me, podcasts are nothing special about how they're used but an audio resource in other classes.
