This paper presents a study with undergraduates of two chemistry courses. the Chemistry course A. and the Chemistry undergraduate course B. The study aims to investigate the Social Representations (SR) of these two groups about "experimentation" and to establish relations between these representations and the formative context of these students. https://www.roneverhart.com/Short-Porch-Mortar-USSSA-Pro-M-12-Slowpitch-Softballs/
