Failed Experiment with the help of a Plant Fairy

We are learning about what plants need to grow.  Water, sunlight, good soil, a seed, and some air- basic ideas.  We did an experiment with 4 different pots.  We gave them certain things to see what would happen to them.

The fourth pot was not given water or sunlight and it grew the most.  The first pot was given water and sunlight and it did not grow at all.  We are speculating that a magical plant fairy came and watered the last pot so that the pepper plants could grow.  My wonderful experiment foiled, silly plant fairy.
