Karl is conducting an investigation to see if his plants grow better in the window. Construct an explanation to identify the criteria for this to be a fair test.

• Karl should only water some of the plants in the investigation

• Karl should keep all other variables the same for the test to be fair

• Karl should give some plants Miracle Grow and others not
