The Concept: Gardening can be another way to encourage scientific discovery and mathematical thinking. The children will experience planting radish seeds and growing them into vegetable plants. Once the radishes are grown and harvested, students can compare sizes, count the radishes, and even cut them and taste how bitter they are. Variations include growing peppers, cabbages, lettuce, herbs, cucumbers, squash, or eggplants. Each type of plant provides opportunities for observation and measurement.
