Rats and Wires: A Science Project | Science Fair Projects | STEM Projects
Ever noticed how rats seem to love chewing on wires? This science project will explore why they do this and what can be done to prevent it.


The hypothesis is that rats prefer to chew on telephone and PVC wires.

Method & Materials

You will place three rats in a cage without food for one day, then pass different types of wires through the grills of the cage and leave them there for 24 hours. The next day, the wires will be inspected for bite marks.
You will need three rats, a rat trap (cage-type), telephone wire, coaxial cable, red PVC wire, black PVC wire, a 3 core power cable, speaker wire, and a rubber mat.


It was observed that the rats preferred to bite the telephone cables and the PVC wires with or without current flowing in them. The hypothesis that rats prefer to bite telephone and PVC wires was proven to be true.

Why do this project?

This science project is interesting because it explores why rats chew on wires and what can be done to prevent it.

Also Consider

Variations of this science project could include using different types of animals like mice or squirrels, or using different types of wires such as Teflon coated wires.
