Standard(s) Taught


SC.8.P.8.4 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.


SC.8.P.8.3  Explore and describe the densities of various materials through measurement of their masses and volumes.


SC.8.P.8.2 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.


SC.8.P.8.1 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.


SC.8.P.9.2 Differentiate between physical changes and chemical changes.


SC.8.N.1.6 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.


  1. 8.P.9.3 Investigate and describe how temperature influences chemical changes.


SC.7.N.1.4 Identify test variables (independent variables) and outcome variables (dependent variables) in an experiment.


SC.8.P.9.1 Explore the Law of Conservation of Mass by demonstrating and concluding that mass is conserved when substances undergo physical and chemical changes.


SC.7.N.3.1 Recognize and explain the difference between theories and laws and give several examples of scientific theories and the evidence that supports them.


SC.8.N.1.1 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. 



SC.912.P.8.2 Differentiate between physical and chemical properties and physical and chemical changes of matter.

SC.912.P.8.1 Differentiate among the four states of matter.

Learning Targets and Learning Criteria

Students will:

• classify substances based on their physical properties, including: 

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 

• determine the physical property being analyzed given data from a tablc

•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

• 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

• differentiate physical and chemical changes in matter

• cite examples of physical and chemical changes in matter

• investigate physical and chemical changes in matter

• explain how temperature influences chemical changes

• explain why mass is conserved when substances undergo physical and chemical changes according to the Law of Conservation of Mass

• investigate the law of conservation of mass using models, such as: o chemical equations, experiments, and demonstrations
