Good morning Nobbyy, DoodleBerry, Egg Bramhill, I am sorry it took me to now to respond to all of the excellent advice you all offered. However,
most of you know I am not tech inclined, but learning. The code below is the YouTube Video I am interested in.

Now, even when i've added ?rel=0&hd=1 it does not seem to make a difference. Could it be do to what DoodleBerry mentioned? These advertising folk want visitors to their videos to go to other videos they advertise? I chose this particular video because I want one that was 2 minutes or less, so that our website could give some other factors, but we are a school and want to teach others about this application.
I more than appreciate each of you reaching out to help. That is what makes this forum so awesome and kind natured.
