Suggestions for providing science experiences for children in kindergarten and grades one and two are given in this first part of the Victorian Education Department (Australia) guide to the elementary school science curriculum. (See SE 012 720 and SE 012 721 for additional guides to this curriculum.) The suggestions are illustrated by brief case studies of successful teaching episodes, particularly where the activities have provided material for written expression, mathematics, and social studies as well as for science. In all cases the emphasis is on direct student experimentation and observation, with minimal teacher direction. Many possible activities are given for introducing "discrimination and classification," and "interactions and change" are suggested using living and non-living materials as examples in both cases. An appendix contains hints on collecting, maintaining, and using living organisms in the classroom. A second appendix provides ideas for developing children's awareness of time. (AL)
