Overview:
In this lesson, students will be able to explain that the density of a substance has to do with how heavy it is compared to the size of the object. Students will also be able to explain that density is a characteristic property of a substance. Students are introduced to the concept of density and that density has to do with how heavy something is relative to its size. Students are also introduced to the idea that whether a substance sinks or floats in water is a characteristic property of that substance and does not depend on the amount of the substance. Students also learn that if an object is denser than water it will sink when placed in water, and if it is less dense than water it will float.
