Taking multiple photos with different lighting/effects on a Nikon D3100?

I use a Nikon D3100, and I understand the parts of the camera and use manual mode, but don't necessarily understand every single feature it holds.

I want to know if there is a way I can take two identical photos, black and white and color, at once, within the camera.
