Mo6-L1a: The Properties of Materials               Mo6-L1b: Metals and Non-Metals




               A conductor is a material that allows for heat to
               easily pass through it (thermal conductor) or        Mo6-L1b          Metals and Non-Metals
               conducts electricity well (electrical conductor).
                                                                  KEY CONCEPTS:
                                                                  1. What are the physical properties of metals?
                                                                  2. What are the physical properties of non-metals?
                                                                  3. How do we use certain metals?



                                                                              Vocabulary A-Z

                                                                              Let us learn some vocabulary


                                                                  metals
                                                                  a material that conducts electricity and heat well.

                              Key Concept                         are good insulators of heat and electricity.

                           The Properties of Materials
                   What is the difference between strength and
                                  hardness?

                                                                  a metal made by combining two or more metallic
                                                                  elements









                                 SUMMARY

                           The Properties of Materials
                  We use physical properties to describe or
                               classify matter.

                 We choose materials based on their physical
                        properties to make products.
