You conduct an experiment to determine how effective a fertilizer is on pepper plants. You give 10 pepper plants no fertilizer each day, 10 pepper plants 1 g fertilizer each day, 10 pepper plants 5 g fertilizer each day, and 10 pepper plants 25 g fertilizer each day. Your friend conducts a similar experiment using the same fertilizer. He gives one pepper plant 1 g fertilizer each day, one tomato plant 5 g fertilizer each day, and one squash plant 25 g fertilizer each day. Explain why your experiment is better than your friend's experiment. Cite three aspects of your experiment that are better than your friend's experiment, and explain why each is better.
