This study investigated the effect of science experiences on the fifth-grade Trinidadian child's concept of Piagetian physical causality. The sample comprised 835 children from 37 schools. The tests used were the Concept Assessment Kit—Conservation Forms A & B, the Metropolitan Achievement Test, Form C, and two clinical interviews which assessed the child's concepts of living and floating. The experimental group scored significantly higher than the control group.

Until recently the West Indian islands have been utilizing curricula developed in other countries. In the late sixties a few islands began to develop their own curricula. The pressure of demand from the new secondary schools for the immediate provision of material led to the rapid and efficient production of detailed curriculum guides but often precluded any fundamental study of the way children in the schools actually think.
