Sink or Float?

Kindergarten is learning about what makes an object float or sink. We learned that the weight of an object is not the only factor that will determine whether an item will sink or float. We saw pictures of an anchor and decided that it was sinking in the picture. We then looked at a picture of a blow up pool toy and decided it floats because of the air inside of it. Kindergarten learned that the shape and what an object is made of is what determines if an item will sink or float. For example a boat in the ocean is a heavy object but does not sink...why? The material and shape of it are what allow it to float. Kindergarten made a chart to keep track of their predictions of whether various object we collected would sink or float. As we went along, we put a smiley face in the float or sink column. It was fun to learn about predicting!
