Introduction Scientists use animals when the use of
humans is either impractical or unethical.For example when scientists investigate
fetal alcohol syndrome, they cannot give alcohol to pregnant women but they can give to pregnant animals such as rats.
Scientific research with animals has contributed to many important advances in scientific & medical knowledge.

Intro Cont. Mice and rats are a useful model for
studying the effects of alcohol. The SD rats are more active during the
night then during the day.SD rat is a general model for the study
of human health and disease.The SD rats is a widely accepted,
dependable, general purpose research model used in virtually all disciplines of biomedical research including toxicology and pharmacology.

Methods We feed EtOH to SD rats once a week. We weight
the bottles into grams (g) before we feed them and also after we feed them.
Record the time we place the bottles on the cage.Wait exactly one hour before we remove the bottles.Each rat has its own separate EtOH and H2O bottle.There is 22 SD rats, Each bottle is numbered 1-22
for rat 1-22 there was sign that was set up for the bottle.
Bottles with orange tape are for EtOh and those with blue are for water
(rats#1 gets orange#1 and blue #1)

Que$tionDo SD rats drink more alcohol (EtOH) than water (H20), or more water (H20) than alcohol (EtOH)?
