In this article Rebecca Kurson describes her school garden, now in its second year, as one that the lower school (preK-5) students plant and observe as often as possible. They call the garden an "outdoor classroom," and the younger students are particularly interested in how the plants grow. Kruson had lots of garden activities planned--the challenge was to make them into learning experiences. She decided to focus on the parts of plants. Herein she describes how the students used art projects to investigate the basic parts of a plant: the roots, the stem, the leaves, the petals, and the seeds. In a final art project, the class put the parts together and studied the system as a whole.
