Brian and Jack decided to investigate which water fountain at school has the coldest water. The two boys take measurements using identical equipment and return several minutes later with four temperature recordings. Surprisingly, even though the two boys measured the same fountains, their data showed different temperatures. Some of Brian's temperatures were lower than Jack's. Which statement would most likely explain the differences in their data?

• Brian walked around the school and Jack ran.

• Brian kept the thermometer in the water longer than Jack did.

• Jack guessed at his measurements and Brian did the real measuring.

• Brian used a Fahrenheit thermometer and Jack used a Celsius thermometer.

• Take the eggs back to his lab and put some under a light to see if they need sunlight to hatch.

• Watch and observe the nest of eggs each day to gather evidence.

• Buy a turtle from the pet store and observe it at his lab.

• Go to his public library to read about turtle eggs.
