This article from the JAE special science issue suggests that teachers who are responsible for science instruction of several or all grades should develop a program that meets the needs of the students without exceeding the teacher's energy. Teachers should use the multigrade unit plans developed for grades 1-4. Teachers of upper-grade students should outline the year's program, plan in advance what learning experiences will be provided, and combine curriculum with common objectives. Guidelines for planning a science program for the multigrade program are supplied.
