Matter (Unit 2)
STANDARD I: Students will understand the structure of matter.
Objective 1: Describe the structure of matter in terms of atoms and molecules.
a. Recognize that atoms are too small to see.
b. Relate atoms to molecules (e.g., atoms combine to make molecules).
c. Diagram the arrangement of particles in the physical states of matter (i.e., solid, liquid, gas).
d. Describe the limitations of using models to represent atoms (e.g., distance between particles in atoms cannot be represented to scale in models, the motion of electrons cannot be described in most models).
e. Investigate and report how our knowledge of the structure of matter has been developed over time.
Objective 2: Accurately measure the characteristics of matter in different states.
a. Use appropriate instruments to determine mass and volume of solids and liquids and record data.
b. Use observations to predict the relative density of various solids and liquids.
c. Calculate the density of various solids and liquids.
d. Describe the relationship between mass and volume as it relates to density.
e. Design a procedure to measure mass and volume of gases.
Objective 3: Investigate the motion of particles.
a. Identify evidence that particles are in constant motion.
b. Compare the motion of particles at various temperatures by measuring changes in the volume of gases, liquids, or solids.
c. Design and conduct an experiment investigating the diffusion of particles.
d. Formulate and test a hypothesis on the relationship between temperature and motion.
e. Describe the impact of expansion and contraction of solid materials on the design of buildings, highways, and other structures.
