The students were excited to be beginning a new science unit - balance and motion! During this unit of study, students will explore stable (balanced) and unstable systems, using counterweights to change the center of mass of the systems. This week our focus is balance. Students are experimenting with various objects and discovering how they can be balanced. Yesterday we introduced the idea of counterweights being used to balance objects.
Later on they will also explore two types of motion--spinning and rolling--first through trial and error, and later through more systematic explorations.
Through the experience-based investigations, students begin to develop a sense of variables, which they control to produce desired outcomes.
