Jane and Jill wondered if the water plants required was related to the temperature of the air around the plants. The girls planted three pots of grass seed. Once the seeds germinated, they placed one pot in the sun, outdoors. They placed the second pot in the shade, outdoors. Finally, they place the third pot in a sunny greenhouse. All conditions were kept constant. The girls did not water any of the pots. They recorded the daily air temperature in all three locations, three times per day: 8:00 AM, 12:00 PM; 4:00 PM.

What would be the next logical step in Jane and Jill's experiment?
