Is this playdrism?(the thing where Du copy crap from someone else and take it as your own.)

Okay, so i was doing this stupid book on Mummification Process and i went on the internet and copy and pasted some of this stuff for it. I changed some of the words and took some words out. But is that considered playdrism? If i is i get a referral becasue my teacher is a beotch and ill get in big trouble. Please try to give a definate Yes oder No.
