control group- rats made sick but not given saccharin
experimental- rats given saccharin
independent- saccharin
dependent- how much saccharin they drink
Procedure:
The rats would be given saccharin and then 30 min later exposed to radiation, 3 days later they would record the sickness

Difficult to decide if it was ethical- could be unethical because of sickening the rats or could be ethical because the rats were well fed and had water.
