Due to the increase of acid rain over the last few decades, the pH levels in lakes and streams seem to be decreasing. While certain
animals can tolerate low pH levels, others are extremely sensitive to the effects of acid rain and cannot live under the conditions.
Candice is working on a project to determine whether acid rain is decreasing the amount of bass and mayflies in a lake in her
hometown. She is using the scientific method. To MOST accurately test the pH of the lake, Candice should useas
part of her experimental design procedures.
A) litmus paper
B) hydrion pH papers
C) a portable digital pH meter
D) a naturally occurring indicator like red cabbage juice
