Mrs. Hernandez

Multiple Choice

Three scientists in different counties have been trying to find a cure for a disease. Each scientist has been doing a different experiment. What would be the BEST way for these scientists to find a cure quickly?

• publish their results to show that the other scientists are wrong

• decide which scientist is doing the best experiment and repeat his experiment

• continue working separately so they don’t mix up their experiments

• communicate with each other to explain their work

Multiple Choice

What would happen if a person did not write clear procedures and someone else tried to copy their experiment?

• the results would be slightly different

• the results would be the same

• it would be easy to do the same experiment

• there would be no way to replicate the experiment

Multiple Choice

Kaitlyn grew plants outside in different soils for her school science fair. She did her experiment three times. Each time, she recorded plant height daily and also wrote observations in an experiment log. The second time she did the experiment, her data was very different from the data in the other two experiments. Which of the following observations in Kaitlyn’s experiment log might explain the difference?

• She watered her plants the same amount each day.

• It rained for three days during the second experiment.

• The plants were all grown on the patio behind her house.

• She followed her procedure very carefully each time

Multiple Choice

A famous scientist did an experiment and published his results. When a scientist in another country repeated the experiment he got very different results. What should the second scientist do?

• tell everyone the first scientist was wrong

• decide his results must be wrong

• review both experiments to determine why the results were different

• change his data to match the famous scientist’s data
