Not actually knowing what you mean (my brain is small, but I can make fire) I looked on google images and there were a couple. But as I said, I have no idea what you mean so the diagrams could be completely wrong.
That's all the help I can offer, sorry
Some days it's not even worth knawing at the straps

i think i got a good 1. I will be testing on how a mouse's nose reacts to diffrent types of food in diffrent types of light

Tony,
Mice may be colour blind:-
“Although the cones in the rat eye are shown to have sensitivity to green and UV light, behavior experiments have demonstrated that rats lack color vision.”
http://www.rmca.org/Articles/vision.htm
“Mice in their natural state are crepuscular or nocturnal. That is, they are active at dusk and during the night, and quiet during the day light hours. Their eyes are adapted to this pattern of life. Nearly all mice dislike bright light. Even those with pigmented eyes will usually avoid it, while albino mice with pink eyes will find bright light quite blinding. If albino mice are kept in bright light, their eyes and their visual cortex can be damaged (Clough, 1988). There are two ways of making the light level comfortable for them: one is to keep the level of ambient light in the cage at no more than 60 Lux (Clough, 1988) and the other is to make sure that they are caged in such a way that they have a dark place into which they can retreat. Ideally, they should be offered a combination of the two.
Because the retina of the night-adapted eye of the mouse is largely composed of rod cells, they probably have little or no color vision. They do not distinguish the red end of the spectrum. They may be able to make some color distinctions at the blue end of the spectrum, but that issue remains undecided.”

“Mice have good senses of smell, taste and hearing, however they have poor vision and are colour-blind”

Tony,
if you want a Science fair project which involves an organism's preference for certain colours of light....
