EXPOSURE
Exposure is the amount of time is it takes the for the light to come in. Pictures can be over exposed or underexposed. Which means some tend to be darker and some tend to have too much light. Along with just over exposer or under exposer there is also the shutter speed and then aperture. The shutter speed is the speed in which it shuts, it is measured in fractions of seconds. The aperture the lens taking in the light and for a certain time, aperture is measured in f/stops. f/stops are on scale from f/1.4 to f/22. to calculate the f/stops you must use the formula, see below. Shutter speed and aperture relate because the shutter is when or how much light is expose to the sensor. Shutter is measured in 1/2000. Aperture is measured in f/stops and is how much light is let into the camera. Some camera settings that let you use aperture and shutter speed is manual. Metering is when you have automatic exposer.

Some ideas for further research.
What are sample shutter settings?
What are some sample F-Stops? How is an F-Stop calculated?
What is a "Stop" (for shutter and for aperture).
What is the relationship between Shutter and Aperture? (Specifically based off of the settings you've talked about)
What camera settings allow you to set the aperture and shutter.
What is metering? How does the camera meter?
Add to your research using the questions above.
Like Mr. H said, you'll want to talk about how to adjust aperture to work with shutter speed and the opposite way.
