描述
Why do some things float and others sink? Does a small, wide container hold more water than a tall, thin one? How can you make a toy boat that floats sink to the bottom of a bathtub? Fun-filled activities encourage young children to use familiar and safe objects found in their homes or classrooms to make observations about the world around them. (Ages 3 to 8).
