Take two or more of the same plant and grow it in different conditions, and compare them. Experiment with watering levels. Some plants, such as the peace lily, perk up within an hour or two of being watered. If you have a variety of houseplants, let your child feel the leaves. Some feel fuzzy, some slick and smooth.
