Properties of Matter

Learning Goals:
  1. To explain in detail what matter is and use properties to identify matter
  2. To use mass and volume to accurately calculate density; understand density is a property of matter
  3. Understand the concept of density and how measuring mass and volume are important to find an accurate density measurement
  4. To understand the difference in contraction and expansion, and that volume and density can change depending on temperature
  5. To describe and explain how different substances react when heated
  6. To understand what happens to a substance when it makes a phase change
  7. To know and explain the difference between a pure substance and a mixture
  8. To know the characteristic property of solubility and explain how it can help you identify a substance
  9. To understand what happens to the mass and volume of a substance when items are combined to form a solution
  10. To understand how evaporation can cause solutions to separate back to their original form
  11. To explain why it is important to know the composition of a solvent before using it to remove stains
  12. To know that a solution can contain more than one solute and how to find out the composition of certain solutions
  13. Solutions and other types of mixtures can have unique chemical and physical properties that are different from the properties of the individual substances from which they are made
Success Criteria--students will be able to:
  • use the formulas for measuring mass, volume and density of a regular and irregular object
  • predict whether a substance will float or sink in water, and how objects will behave in a density column
  • explain why air is matter, and calculate its approximate density
  • use a laboratory thermometer accurately
  • explain why density changes with temperature
  • explain why changes in substances caused by heat may be reversible or irreversible upon cooling
  • discuss chemical reactions and phase changes as characteristic properties
  • explain why mass is conserved or lost when changing state
  • analyze results and discuss reasons for experimental error
  • explain the difference between heterogeneous and homogeneous mixtures; use different criteria to identify and define pure substance and mixture
  • explain the difference between soluble and insoluble, solution, solute and solvent
  • explain how a solid can be recovered from a solution
  • explain why chromatography can be used to analyze solutions
  • separate several solutes from a solution that contains a mixture of solutes
  • explain the effects of adding different quantities of salt to ice and salt to boiling water
