Big Ideas
  • The structure of substances at the bulk scale is influenced by the strength of electrical forces between particles.
  • Investigations can reveal how differences in particle arrangement and type impact observable properties of substances.
Essential Questions
  • How can an investigation of substances at a large scale provide evidence about the forces holding them together?
  • What is the relationship between the structure of a substance and the strength of electrical forces between its particles?
  • How do different substances compare in terms of the arrangement and strength of forces at the bulk scale?
  • What types of evidence can help us infer the strength of electrical forces inside a substance?
  • How can designing and conducting investigations help scientists understand the properties of materials?
