IPC Unit 8: Properties of Matter

During this Unit

This unit focuses on chemical and physical properties of matter with an emphasis on the states of matter. Students analyze the properties of elements and compounds and determine their classification as physical or chemical properties. Students relate chemical properties to chemical arrangement of a substance. Students will also relate the arrangement of particles to the physical properties of the states of matter through investigating changes in states of matter.

 

Misconceptions:

  • Students may think atoms can be seen with a classroom microscope rather than understanding that images of atoms can be generated from electron microscopes.

  • Students may think materials have the same properties regardless of the state of matter, rather than understanding that substances may have different properties when they undergo a change of state.

 

Key Content Vocabulary:

  • Buoyancy – tendency of an object to float or rise in a fluid (air or liquid) due to the upward force exerted by the fluid

  • Change of state – a change from one state (solid or liquid or gas) to another by changing the physical arrangement of particles without a change in chemical composition

  • Chemical bond – force that holds atoms together in a compound

  • Molecules – an electrically neutral group of at least two atoms in a definite arrangement held together by chemical bonds

  • Viscosity – resistance of a liquid to flow; thickness or resistance to pouring
