Helia is a sunflower, Helianthus annuus, and a dicot. Zea is corn, Zea mays, and a monocot. Your child not only learns about monocots and dicots in this volume, but he also learns about botanical nomenclature and a bit of math, geography and culture, and even some art and literature. Don’t worry, though, the focus is still on science. Lots of science. But, Helia and Zea are important to people and this study acknowledges that by integrating human touchpoints into the study of plants.
