Inspire the natural-born scientist in your child! Children will engage their curiosity by making predictions and observations about whether different objects will sink or float when placed in water – the scientific method in action! After this guided exploration, the class will listen to a reading of “Who Sank the Boat?” before building and testing their own weight-bearing boat. Will it sink … or float?
