Third graders had lots of opportunities to test out their hypotheses about how and where plants grow best in Dena Weiss-Tisman’s class this spring. With their teacher they designed an experiment to find the best place for growing basil. Along the way they discovered that basil seeds are about the size of a period in their books. Seedlings were started in the classroom window, on a bookshelf and in a drawer. Another group were brought to Harlow farm greenhouse. Even I was surprised at the outcome. Perhaps because our classroom window faced south and because the seedlings were consistently watered, the classroom window  seedlings did just about as well as the ones in the commercial greenhouse.
