Enduring Understandings

 

The student will understand:

  • Chemistry is the study of matter and the changes it undergoes.
  • Atomic theory is the foundation for the study of chemistry.
  • Atoms interact with each other
  • Changes in matter are accompanied by changes in energy.
  • Chemical bonding occurs as a result of attractive forces between particles.
  • Chemical reactions are predictable and occur all around us.
  • Periodic trends in the properties of atoms allow for the prediction of physical and chemical properties.
  • Particles of matter are both similar and different
  • The way a material behaves depends on how its atoms are arranged.
  • The three dimensional structures of organic molecules play an essential role in determining the physical and chemical behavior of the molecule.
