Chemistry A
SC.11.ChemistryATF.Bnet4copy
In an attempt to compress the myriad of possibilities of what comprises chemistry into a manageable course (effectively simplifying those 'everythings' in our definition above), this half of the chemistry course is divided into four parts. The first unit looks at matter qualitatively, from a macro- and then microscopic perspective; while the second unit uses some quantitative relationships to understand how matter behaves. The behavior of matter is most familiar to us, and aids in the transition to the third unit, which looks at the structure of matter. The final unit in this half of the course covers the periodic table which serves to organize and summarize matter by its properties.
Enduring Understandings
The student will understand:
- Macroscopic observations reflect the submicroscopic structure of matter.
- Everything is made of matter and atoms are the fundamental building blocks of matter.
- Properties of matter can be divided into chemical and physical changes.
- The Kinetic Molecular Theory explains the properties of solids, liquids and gases.
- The chemical elements are the fundamental building materials of matter and are best understood by considering them as composed from atoms that always retain their identity.
- Chemical and physical properties of materials can be explained by the structure and the arrangement of atoms, ions or molecules and the forces between them.
- The properties of elements and their organization in the periodic table reflect the valence electron configurations of the elements.
- Periodic trends in the properties of atoms allow us to predict physical and chemical properties.
- The state and national standards this course targets can be accessed inside the folder.
Essential Questions
- How are the interactions of matter expressed qualitatively?
- How do we know that matter has structure and order?
- How does the organization of the periodic table reflect the structure of matter?
- How does the motion of matter affect its properties
- How does matter interact at the atomic level?
- How does matter interact at the molecular level?
- How do the properties of solutions differ from those of other classifications of matter??
