Even as the 1990s seem to be ushering in a new wave of "hands - on" science, one cannot help but look back to the late 1960s when a previous wave of experiential science programs was crashing ashore. Two programs notable among those spawned during the late 1960s and early 1970s were Elementary Science Study (ESS) and the Science Curriculum Improvement Study (SCIS). ESS units, originally a group of fifty-six independent units covering topics from the physical, biological and earth sciences for K-9, incorporated an instructional strategy called "messing around." "Messing around," which took place during the early portion of an ESS unit, allowed the children to play with and/or explore the equipment and materials utilized in the unit. The ideas behind the "messing around" strategy were to let the students become familiar with the unit's equipment and materials as well as to begin learning something on their own without a lot of teacher guidance or input.
