Right next to the on/off switch is a dial that has things on it like M, S, A, P, C, and some symbols. The M stands for manual. Set it for that and you can select your shutter speed and aperture and you will see what effect those adjustments will have on your screen. Shutter speed freezes or blurs motion. Aperture has an effect on something called depth of field (how much of the foreground and background will be in focus).
If you use a tripod, it will hold your camera absolutely motionless, so you can take longer exposures when the light is dim and hand tremors won't cause you to get blurry photos. In manual mode, you can choose your shutter speed. If you use a tripod, it is a good idea to use a camle release. A cable release is an item that looks like a cord with a hypodermic syringe on one end and a little bolt on the other. The bolt screws into your shutter release button. Pressing the plunger on the "hypodermic syringe" trips the shutter without touching the camera and causing it to shake. For cameras that don't have a threaded hole in the shutter button, you can use the self-timer to do the same thing. Cable releases are more practical for shooting kids with the attention span of a hyperactive hummingbird because you can shoot when you want, without having to wait several seconds for the self-timer to run down (by which time the kids will have lost interest and will want to run off and play with a dead rat carcass).
It is going to be worthwhile to read the entire owner's manual that came with your camera. There is a lot of information in there that you can use. If you don't have an owner's manual, you can go to the Kodak website and download one for free.
