Essential Question:

How can we explain the properties and behavior of matter by considering it as being composed of tiny, constantly moving particles? 

Iowa Core Content Standard Correlation:

HS-PS1-1: Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

Understand:  The relationship between mass and volume is most commonly expressed through density, which is defined as mass per unit volume (density = mass/volume).

Know:   

(a.) Draw particle models to represent an object’s mass, volume and density.

(b.) Mathematically and graphically determine an object’s density.

(c.) Determine the identity of an unknown object using density.
