Out of school science sequence for paired schools

Sixth grade children representing each of the eight Philadelphia Public School Districts attended morning sessions at the Franklin Institute one day a week for a seven‐week cycle. Each weekday, a different pair of schools participated, thereby, involving the same 10 schools each week for the cycle. The two program cycles involved 700 children and 20 teachers from 20 different schools. The first cycle was used as a “tooling‐up period.” During this time instruments were developed. During the second cycle measurements of science information and student interactions were made.
