The sample consisted of 67 third-graders from four classrooms in two elementary schools in a southeastern state. The experimental group interacted with activities, which are closely bound to the development of the concept of force. The control group learned the same subject matter through lectures and demonstrations designed by the class teacher. Both groups were pre-tested and post-tested on a task instrument. Informal classroom observations were conducted to ensure that the teachers were implementing the treatment as expected. The data were analyzed using descriptive statistics and qualitative research procedures. A chi-square test of independent samples was employed to test the significance of the change. Results showed t...
