This series of journals includes volumes 1-4 of "Growing Ideas," a journal of garden-based learning. Each issue provides instructional ideas, horticultural information and a forum for exchange among teachers using classroom gardening to stimulate learning. Ideas in each issue are separated into three sections. The "Green Tips" section presents articles related to gardening and activities that encourage student investigation. The "Exchange" section contains letters from readers that share teaching ideas, information about local projects, and responses to prior issues. The "Resources" section reviews instructional materials and provides information about resource availability. Among the topics discussed in these issues are: the National Aeronautics and Space Administration's (NASA) SEEDS project, peanuts, lunar harvest, hydroponics, biospheres, energy, ponds, ladybugs, herbs, worms, transplanting, mathematical problem solving; bulbs, global gardening, butterflies, compost, and wildflowers.
