Yoshi is investigating the way surface area affects the evaporation of water. She pours the same amount of water into a shallow dish and into a tall, narrow jar. She measures the volume of water left after a few days. What is the best reason for Yoshi to record her steps and results carefully?

• The experiment will still work if it is cloudy

• She does not need to do the experiment again

• No one else will have to carry out the experiment

• Another student can repeat the experiment to check the results

Mrs. Wakula mixes salt and pepper in a beaker of water. Then she pours the mixture through filter paper. She finds that the filter paper separates out the pepper but not the salt. If this conclusion is correct, what should happen if Mr. Wrye repeats the experiment?

• He should get the same results.

• He should follow a completely new procedure.

• He should use different amounts of salt and pepper.
