A Biological Question - Which fertilizer is better: brand A or brand B?
My Hypothesis: brand B, because I have seen it advertized on TV.
The Experiment:
- Use 3 identical plants.
- Give water to each plant equally on Fridays.
- Plant 1 will just get water.
- Plant 2 will get water with fertilizer A added.
- Plant 3 will get water with fertilizer B added.
- Measure the height of each plant (in centimeters) on Mondays.
- Run the experiment for 2 months.
- At the end of the experiment, the best fertilizer will produce the tallest plant.
