So in all honesty this video was more confusing then the first one, all I really picked up in the video was "the faster you go the greater affect of time dilation." So to put that into laymen's terms time dilation is a difference of elapsed time between two events as measured by observers either moving relative to each other or differently situated from a gravitational mass or masses. Most of the video just include demonstrations and actual events that support this theory making it an actual fact. The only issue with this would include the complexity of this with the students when presenting this, I will have to converse with my fellow partner and we will have to decide if we want to use this information in our presentation. The last thing we want to do is bore people with all of our facts and then tune out.
