Keep the plants under different light conditions. Separate them into three groups of two plants. Water one group twice a day, the second group once a day, and the third group every other day. Measure the height of the plants daily.

Keep the plants under different light conditions. Water all of them one day and measure their height. The following day, water the plants twice and measure their height again.

The best option for the scientist is:
Keep the plants in the same light conditions. Separate them into three groups of two plants. Water one group twice a day, the second group once a day, and the third group every other day. Measure the height of the plants daily.
This approach controls for light conditions, which is an important variable, and allows for clear comparisons among the groups with different watering frequencies. Measuring the height daily helps track the plants' growth over time.
