Spring is an exciting time in any kindergarten classroom. The children are communicating better, and they have begun working more independently. Their critical-thinking skills are growing each day. Last year, as the warm days of spring teased our senses, a plant unit seemed especially enticing, so the author created four interactive, plant-themed learning centers that developed science-process skills, including observing, comparing, recording data, collecting data, sorting, and classifying. The centers addressed four curriculum areas-mathematics, fine arts, communication arts, and science, and they incorporated the use of a journal in which students wrote or drew every day, further developing students improving communication skills. Though the tasks at each center embraced different parts of the curriculum, they all related to plants and gave children a chance to "get their hands dirty" and experience the joy of discovery and exploration-an important goal of our kindergarten science curriculum. While she developed plant-themed learning centers, the approach can be used effectively with nearly any topic, and the author encourages readers to try learning centers with their students. The lessons at the centers came from the author's local curriculum, the AIMS book Primarily Plants (Hoover and Mercier 1990), and Successlink-a Missouri Department of Education website where educators share teaching ideas (see Internet Resources).
