Brief Summary of Unit
Students will understand (that):
• Molecules and Compounds have distinct characteristics and properties.
• Chemical bonds form and hold molecules and compounds together.
• Molecular structure affects substance properties.
• Ionic bonds transfer electrons, form from oppositely charged ions and form strong bonds.
• Covalent bonds share electrons, usually form from nonmetals and have weaker (than ionic) bonds.
• Metallic bond form from metals combining and easily conduct electricity.
• Polyatomic ions act as a single unit in a compound.
• How to name and write the formulas for ionic and covalent compounds.
• The difference between molecular and empirical formulas.
• Organic compounds are covalently bonded and contain carbon atoms.
• The difference between alkanes, alkenes and alkynes.
• Polymers have repeating subunits, its structure determines in elasticity and some are natural and some are artificial.
• Biochemical compounds are essential to life and include carbohydrates, proteins and DNA.
• What differences and similarities exist between molecules and compounds?
• How do chemical bonds form and why are they important?
• What are ionic bonds and their characteristics?
• What are covalent bonds and their characteristics?
• What are metallic bonds and their characteristics?
• What are polyatomic ions and why are they important?
• What are the steps used to name and write formulas for ionic and covalent compounds?
• What is the difference between molecular and empirical formulas?
• What are some examples of organic compounds and why are they important?
Students will know: (Knowledge)
• Chemical bonds and how structure affects properties of a substance.
• Ionic, covalent and metallic bonds…formation and properties
• Polyatomic ions and their role in compound formation.
• Naming and writing formulas for compounds.
• Organic compounds (contain carbon) examples.
• A Polymer’s structure affects its uses.
• To distinguish between biochemical compounds (carbohydrates, proteins and DNA) and why each is important.
Students will be able to do (Skills)
• Distinguish between molecules and compounds by identifying properties and characteristics.
• Name and explain the three types of chemical bonds.

• Distinguish and explain the differences between molecular and empirical formulas.
• Explain the difference between alkanes, alkenes and alkynes.
• Explain what a polymer is and describe characteristics of a polymer.
• Define what Biochemical compounds are and explain why they are essential to life.
• Compare and contrast carbohydrates, proteins and DNA.
• Cite evidence to support their opinion.
• Vocabulary Activities
• Collaborative groups
• Distributed practice (writing formulas, writing names from formulas, writing formulas from names)
• Discovery or Inquiry learning (Ionic and Covalent Bond Lab)
• Compare and Contrast (Ionic and Covalent Bonds, naming of ionic and covalent bonds)
• Pair students; students with high ability, low ability, and other.
• Extended time on tests or assignments
• Enhanced learning material
