# Q2W7: December 2 – December 6, 2019

Teacher Jamie Newcomb Comprehensive Science III 8 16 Properties of Matter
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.912.P.8.2 Differentiate between physical and chemical properties and physical and chemical changes of matter.

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.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.

Learning Targets and Learning Criteria

Students will review for the DIA 3 using class demonstrations, review games and review assignments.

The learning targets  being reviewed are:

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

• 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
• o NOS Focus – Inferences and Observations
• explain how temperature influences chemical changes

o NOS Focus – Independent and Dependent Variables and Control Groups
• 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
