Standard 2: Students will
understand the relationship
between properties of matter and
Earth’s structure.
Objective 1: Examine the effects of density and particle size on the behavior of materials
in mixtures. (p. 44)
a. Compare the density of various objects to the density of known earth materials.
b. Calculate the density of earth materials (e.g., rocks, water, air). c. Observe and
describe the sorting of earth materials in a mixture based on density and particle
size (e.g., sorting grains of sand of the same size with different densities, sort
materials of different particle size with equal densities).
c. Relate the sorting of materials that can be observed in streambeds, road cuts, or
beaches to the density and particle size of those materials.
d. Design and conduct an experiment that provides data on the natural sorting of
various earth materials.
Objective 2: Analyze how density affects Earth's structure. (p. 52)
a. Compare the densities of Earth's atmosphere, water, crust, and interior layers.
b. Relate density to the relative positioning of Earth’s atmosphere, water, crust, and
interior.
c. Model the layering of Earth's atmosphere, water, crust, and interior due to
density differences.
d. Distinguish between models of Earth with accurate and inaccurate attributes.
