The best way for a scientist to investigate how often a plant needs water is to conduct an experiment. This experiment should consist of the following steps:

  • Choose a plant species to study.
  • Select a sample size of plants that are of similar size and health.
  • Keep all plants in the same environment and give them the same care (i.e. sunlight nutrients etc.)
  • Divide the plants into two groups. Give one group water every day and the other group water every other day.
  • Observe the plants in each group over a given period of time (i.e. one month). Record any visible changes.
  • Compare the results of the two groups. Record any differences in the health of the plants.

By conducting an experiment such as this a scientist can gain insight into how often a plant needs to be watered in order to thrive. This can be useful information for anyone who is looking to grow plants in their own home or garden.
