Standard(s) Taught

Classify and compare substances on the basis of characteristic
physical properties that can be demonstrated or measured; for
example, density, thermal or electrical conductivity, solubility,
magnetic properties, melting and boiling points, and know that
these properties are independent of the amount of the sample

Explore and describe the densities of various materials through
measurement of their masses and volumes.
Differentiate between weight and mass recognizing that weight is
the amount of gravitational pull on an object and is distinct from,
though proportional to, mass.

Differentiate between physical and chemical properties and
physical and chemical changes of matter.

Explore the scientific theory of atoms (also known as atomic
theory) by using models to explain the motion of particles in
solids, liquids, and gases.

Differentiate among the four states of matter.

Differentiate between physical changes and chemical changes.

Understand that scientific investigations involve the collection of
relevant empirical evidence, the use of logical reasoning, and the
application of imagination in devising hypotheses, predictions,
explanations and models to make sense of the collected evidence.

SC. 8.P.9.3
Investigate and describe how temperature influences chemical

Explore the Law of Conservation of Mass by demonstrating and
concluding that mass is conserved when substances undergo
physical and chemical changes.

Recognize and explain the difference between theories and laws
and give several examples of scientific theories and the evidence
that supports them.

Define a problem from the eighth grade curriculum using
appropriate reference materials to support scientific
understanding, plan and carry out scientific investigations of
various types, such as systematic observations or experiments,
identify variables, collect and organize data, interpret data in
charts, tables, and graphics, analyze information, make
predictions, and defend conclusions

Learning Targets and Learning Criteria

Students will:
• classify substances based on their physical properties, including:
o thermal conductivity, electrical conductivity, solubility, magnetism,
melting and boiling points, volume, and density
• investigate to explain how the physical properties of matter are independent of
the amount sampled, such as: density and conductivity
o NOS Focus – Design a controlled experiment
• determine the physical property being analyzed given data from a table

Students will:
• calculate the density, mass or volume of solids, liquids and gases using the
formula Density = mass ÷ volume
o measure the mass and volume of solids, liquids and gases
• sequence various substances in order of increasing or decreasing density
• differentiate between mass and weight

1. Discuss compressibility, malleability, reactivity, and molecular composition
2. Describe simple laboratory techniques that can be used to separate
homogeneous and heterogeneous mixtures (filtration, distillation,
chromatography, evaporation)

Students will:
• differentiate between solid, liquid, and gas based on their particle motion
• sequence the states of matter by increasing or decreasing kinetic energy
• explain how the state of matter of a substance is related to the average kinetic
energy of its molecules
• predict what happens to the motion of particles during a phase change

1. Differentiate among the four states of matter (solid, liquid, gas and plasma) in
terms of energy, particle motion, and phase transitions

Students will:
• differentiate physical and chemical changes in matter
• cite examples of physical and chemical changes in matter
• investigate physical and chemical changes in matter
o NOS Focus – Inferences and Observations

Students will:
• explain how temperature influences chemical changes
o NOS Focus – Independent and Dependent Variables and Control Groups

Students will:
• explain why mass is conserved when substances undergo physical and chemical
changes according to the Law of Conservation of Mass
o differentiate between a law and a theory
o NOS Focus- Theory vs. Law

• investigate the law of conservation of mass using models, such as:
o chemical equations, experiments, and demonstrations
• design an investigation to explore the Law of Conservation of Mass
o NOS Focus – Hypothesis, Collect and Analyze Data, Draw Conclusions,
and Experimental Error
