Yup, we can see them now.
The fountain is a good test of shutter speed.
Put the camera in Shutter priority mode, then change the shutter speed up to 1/250 of a second and see how the water is frozen in mid air, then change the shutter speed down to 1/15th of a second (this is slower) and put the camera on a tripod (or something to make it steady), now notice how the water is blur of movement.
To try out Aperture priority, aim the camera at the fountain, put the camera into Aperture priority mode, then lower the f-stop to f2.8 or f3.2 this will make the fountain in focus and make much of the foreground and background very nicely blurry (this is a shallow depth of field). Now put the f-stop up to f5.6 or f6 and see how more of the picture is in focus. The higher the f-stop the more of the foreground and background will be in focus (this is a larger "depth of field").
Now go play.
