Sink or Float?
Grade 2 scientists have been exploring liquids and solids and how they react when combined. As part of their exploration, the students have been testing objects that sink or float, and drawing conclusions about the WHY and HOW of their observations. The children used and shared their newfound knowledge about materials and forms that float, in a group project, designing and constructing a floating structure, using recycled materials. The scientists/engineers were all very satisfied with their group collaboration and with their final results: all the boats floated!!
