Shutter Speed Priority Post Assignment

Over the past week and a half i have been out taking pictures for my Shutter Speed Priority assignment. I realized that it wasn't as easy as it seemed, If you didn't capture the picture at the exact time, the picture came out blurry. I set my s\camera settings to a white balance at daylight, an ISO at 400, and i changed shot from single to continuous. I mostly took pictures of my friends jumping out of things, running, skipping, and  leaping. None of which really worked out as well as i had wished. I sorta had trouble on this assignment, and they definitely are not my best pictures. But out of all i took, here are the 3 i think are the best.
