The part of the body that we should closely relate to aperture is the eye. The cornea is like the camera lens. Depending on the light, the iris can expand or shrink.
The smaller the aperture, the less amount of light. The bigger the Aperture, the more amount of light.
If I were to shoot at a school event, Bulldogs and Hotdogs, I'd have to do medium shutter speed for a booth in the middle of the courtyard, seeing as students are moving in front of the camera. As for a food booth under the awning, there'd probably be more action going on, so a setting a little higher than medium. Then as for the dancers' performance, that would be the highest setting possible, with high speed.
The dancing students would be a slower speed, but still fast enough to capture the moments.
The students streaming in through the doors would be a high speed, as well as some shooting hoops in the basketball. At night, I think all would be high speeds of the shutter, as well as the flash, except the dancers in the gyms
The Three Different Settings on a DSL Camera
There are three total settings of shutter speed on the DSL Camera. Aperture mode, which automatically sets the camera shutter settings. Shutter priority, in which you choose the settings and the camera takes the picture. Then there's Manual, where you choose both the shutters and aperture settings.

ISO
Higher ISOs have a particular advantages at sports games because there's much more movement, and high ISO can capture the movement. Low ISO is used when there is a lot of light, and can get more detail, and is clearer.
Use ISO when there is quick movement and there is less light.
On this camera simulator, there are 7 aperture settings: 2.8, 4, 5.6, 8, 11,16,22.
There are also three shutter settings: 1 second, 1/60 of a second, and 1/4000 of a second.
ISO settings are: 100,200,400,800,1600,3200,6400,12800, and 25600.
