Rose designed an experiment to determine how temperature affects the rate of a chemical
reaction. She uses the chemical reaction between an antacid tablet and cold, room
temperature, and hot water. She keeps the volume of water the same. She measures the
time it takes for the chemical reaction to complete. Rose collected the following data:
Which statement describes the most scientific way to conduct the experiment?
A
Rose should replicate her experiment to show that her results are consistent, and she
should ask a friend to repeat the experiment.
Rose should replicate her experiment to show that her results are consistent, and
then she should ask a friend to repeat the experiment with different volumes of
water.
Rose should conduct repeated trials to show that her results are consistent, and she
should ask a friend to replicate her experiment with the same criteria.
Rose should repeat her experiment using different volumes of water, and she should
ask a friend to check that she has not made a mistake measuring the time it takes for
the chemical reaction to complete.
