Socio-scientific issues demonstrate the relationship between science, technology, and society by considering currently unresolved questions. The problem of plastics and their pollution is just one example with important implications for the planet. The aim of this paper is to revisit socio-scientific issues and see them as a way of developing…

A hands-on approach to introduce the chemical elements and the atomic structure to elementary/middle school students is described. The proposed classroom activity presents Bohr models of atoms using common and inexpensive materials, such as nested plastic balls, colored modeling clay, and small-sized pasta (or small plastic beads).

A pre-service science and mathematics teacher participated in an action research project to reform a chemistry course required of elementary and middle childhood pre-service teachers. Activities to emphasize a hands-on approach to learning chemistry and to model teaching science through inquiry for these pre-service teachers are described. The…
