Read the descriptions of two experiments below.
Experiment 1:
A group of students tested to see if the acidity of water
affected pea plant growth. They followed a logical method
and performed their experiment once, using controls and
experimental groups. Their results supported their
hypothesis.
Experiment 2:
A group of students tested to see if bacteria growth in
water was affected by acidity. They used controls and
experimental groups. They repeated their experiment
several times and found the results were the same.
Which experiment most likely has greater reliability, and why?
A. Number 2, because the experiment was repeated, and the results
were always the same
B. Number 1, because it has control groups
C. Number 2, because the experiment was repeated
D. Number 1, because it follows a logical method
