A SEARCH OF RECENT SCIENCE EDUCATION LITERATURE WAS MADE TO DETERMINE TOPICS IN PHYSICS AND CHEMISTRY THAT WOULD BE TESTED FOR SUITABILITY WITH PROSPECTIVE ELEMENTARY SCHOOL TEACHERS. EIGHT CRITERIA WERE SELECTED AND USED TO GUIDE THE WRITING OF LABORATORY ACTIVITIES. SIXTY-NINE PROSPECTIVE ELEMENTARY SCHOOL TEACHERS USED THE EXPERIMENTAL MATERIALS. JUDGMENT AS TO SUITABILITY FOR USE WAS DETERMINED BY EVALUATION OF STUDENT PERFORMANCE. RESULTS INDICATED THAT ALL 29 EXPERIENCES HAD SOME DEGREE OF SUITABILITY WITH 22 BEING DISTINCTLY MORE SUITABLE THAN THE REMAINING SEVEN. CONCLUSIONS AND RECOMMENDATIONS ARE INCLUDED IN THE STUDY.
