  1. COIN DENSITY Pg. 22 of IAN OBJECTIVE: Review density by measuring mass and volume then calculating density.

  2. WHAT IS DENSITY? • The closeness of the particles in a substance. • Gases are the least dense. Liquid and solid particles are much closer and much more dense. • If a substance changes phase, it changes its density: ice is less dense than water and both are much more dense than vapor.

  3. MEASURE MASS AND VOLUME • To measure mass: use an electronic scale. (g) • To measure volume: Of a liquid: measure directly in a graduated cylinder. (ml) Of irregular solid: measure indirectly by subtracting the initial liquid volume. (ml) Of regular solid: length x width x height (cm3)

  4. CALCULATE DENSITY DENSITY = MASS/VOLUME or M D = ----- V (g/ml or g/cm3)

  5. COIN DENSITIES OUTPUT • Find the masses of one, five, and ten pennies. • Find the mass of five dimes. • Find the volume of each of the above using water displacement. • Calculate the densities.

  6. Data for Coin Densities: coins mass volume density LABEL YOUR NUMBERS!!!

  7. CONCLUSIONS Should the density of one penny be different than the densities of five or ten pennies? Why or why not?
