Why bother to look through microscopes or telescopes when you can just sit back and watch a youtube video? 

Short answer: Watching someone else doing something is NOT the same as doing it yourself. Science is how we explain what we notice and observe , and the way we do that is through experiments.  Let's learn from one of our teachers here at Supercharged Science and good friend of mine, Oliver, and his thoughts on this question.
