Hi Christina,
Shutter speed records the way action is displayed. A long shutter speed smears action together, while a short shutter speed stops action.
The aperture controls the amount of area in sharp focus - which is called depth of field. If you focus at 5 feet from the camera, a large aperture will give you sharp focus at just 5 feet. If you took the same picture at a small aperture, you might be in focus from 4 feet to 7 feet, depending on your aperture.
You might want to look at my article for more information:

Thanks,
