Mice vision. I know mice can't see red light but need a web page about this to reference to.?

This is for a 11yr old school project so page needs to be easy to understand. I have searched but can only find very technical data.Mice vision. I know mice can't see red light but need a web page about this to reference to.?
Don't know if this is too technical, but this website states simply ';The poor vision of mice makes them unable to detect color and red light is often used to observe animals during the dark cycle.';

Another site states: ';Rats and mice are colorblind so that the world to them is composed of various shades of gray.


Clear vision of rats is restricted to a few feet; house mice to about 6 inches. However, they can distinguish movement at a considerable distance.';

One site gives instructions to students at a lab: ';Light-dark cycle:





This lab should be done in Rooms 10 or 10 D, E or F in Imholte. Animals are housed in room 10 C, Imholte. They are in a reversed light dark cycle, which means that their lights go off at 10:00 in the morning and on at 8:00 P.M. at night. Since these animals are nocturnal, you should expect them to be most active from 10:00 A.M. to 8:00 P.M. You may choose to test your animals during either the dark or light portion of their day-night cycle (but expect less behavior during the light portion). If you want to enter the animal room during the hours of 10:00 A.M. to 8:00 P.M., you need to turn off all white lights, shut the doors into the lab and the hall and then enter the animal room under red light only. You should observe your animal under red light also, if you are testing between 10:00 A.M. and 8:00 P.M. All rooms are equipped with red light.';

I could not find anything else that would be useful, sepecially for an 11 year old.
