Desribe a controlled experiment you could use to test your hypoyhesis?

To test my hypothesis, I would conduct a controlled experiment where I manipulate one independent variable while keeping all other conditions constant. For example, if my hypothesis involves the effect of light intensity on plant growth, I would set up three identical groups of plants with varying light levels (low, medium, high). Each group would receive the same amount of water, soil type, and temperature. By measuring the growth of the plants over a set period, I can determine the impact of light intensity on their growth.
