Does a mouse smell or see better?Featured science projectScience project video


This science fair project was conducted to compare how mice depend on their senses to complete a maze and locate food. The test was done to compare the senses of sight and smell.


A mouse will be able to find its way through maze more quickly by using its sense of sight rather than its sense of smell.

Mammals, rodent, species, parasites



Mice are mammals. They typically measure about 15 to 20 cm in length on average, from the nose to the tip of the tail, and weigh about 35grams. Mice have thin fur, long tails and come in several shades of black, white or brown. They are also popular as pets as it is easy and fairly inexpensive to care for them.

Mice used to live in farms where they were a nuisance, damaging and eating the crops. Urbanization brought them to ourcities where they now live in the sewers, crevises and drains. Mice are regarded as pests because their urine, feces and bodies contain germs, fleas and parasites that are harmful and sometimes fatal to people (take the bubonic plague, for example, that raged across Europe in the medieval ages, claiming over 100 million lives!). They also damage food, food packaging, and our homes (they chew through wires, furniture and clothing). Although mice are actually herbivores, they have adapted to urban living, by eating all types of food scraps.
