As 1st graders begin to explore the environment around them they make sense of the world. At an early age children learn to engage and interact with the world around them. It is also wonderful to hear that play is important to healthy brain development because it allows children to be creative, use their imagination and their physical, cognitive and emotional strength. In order to build on those explorations 1st grade went to the museum of scientific discovery, Cosmo Caixa! In addition to enjoying all the museum has to offer we took part in an interactive play activity, “Clik”. Through smells, tactile sensations, bubbles, simple machines and instruments the children explored, observed and made scientific discoveries about the world around them!
