Sink or Float?

The students have been introduced to a few objects and 2 containers with water at the science centre.      They are discovering the concept of sink and float!  Some are sinking and drowning says one friend.  We discuss the objects that sink or float.  At home provide some objects in the bathtub and discuss things that sink and float.  Have your child draw a picture of some objects that floated or sank and bring to school to share!
