Instructional Ideas

  • Have paired learners design a lab activity to test the properties of several metals
  • Extend the lesson by creating a research project focused around the uses of ionic solids as insulating materials
Classroom Considerations

  • Assumes some prior knowledge of ionic and metallic bonding
Pros

  • The narrator poses questions then prompts for a pause to allow the class to answer and discuss
  • Animated sequences illustrate the movement of electrons, which helps give students a strong sense of the role electrons play in conductivity and malleability
Cons

  • None
