Chemistry

Week of Oct. 17-19

Objective:  To understand the basic chemical principles that control living things.

Wednesday,  Oct. 17

Lesson Objective:  I will understand the vocabulary of our Chemistry unit.

Opener: What are the two oppositely charged particles of an atom?

Summary: What does the number of electrons have to do with the ability of an atom to make molecules?

  • Introduce vocabulary and properties: Element & Symbol, Atom, Proton, Neutron, Electron, Atomic Wt., Atomic Number, Isotope, & Valence.
  • Assign chapter 2.1 to read (click here for link)

Thursday, Oct. 18

Lesson Objective:

  1. I will show my understanding of the periodic table and demonstrate how to interpret the information that it provides.
  2. I will be able to construct a model of any atom from Hydrogen to Calcium

Opener:  Illustrate  how many electrons are in the valent shell of Nitrogen.

Summary:  Why is Argon a stable atom?

  • H.O. worksheet Periodic Chart Data table.(work in groups of 3)
  • Introduce drawing of the Bohr model for atoms; Oxygen, Hydrogen, Carbon, Helium, Argon, Nitrogen (others through Calcium)

Friday, Oct. 19

Lesson Objective:  

  1. Demonstrate my understanding of the Periodic table and Bohr models
  2. I will learn how the valent shell of an atom tells me how it will bond with another atom.

Opener:  How many atoms of Hydrogen will it take to combine with Nitrogen to form a “happy” molecule?

Summary:  Why does Lithium only give up its electrons to Oxygen?

  • formative quiz: Periodic Chart Data table.
  • Introduce Co-Valent and Ionic Bonding

Week of October 22-26

Objective:  I will learn that molecules interact with other molecule in ways that allow us to have the qualities that give us life.

Monday, Oct. 22

Lesson Objective:  

  1. I will demonstrate that I understand how to draw Bohr models of molecules.
  2. I will learn how to construct “structural models” of molecules.

Opener:  Why does Hydrogen have only one bond line associated with it and oxygen has two associated with it?

Summary: What does the + or – sign at the end of a molecular formula mean?

  • Introduce drawing of Structural models of simple molecules. (H2O, O2, COOH+, NH3, OH-, CO2)
  • Assign 2.2 to read (click here for a link)

Tuesday, Oct. 23

Lesson Objective:  1.  I will demonstrate that I understand how to draw Bohr models of molecules.

2.  I will learn about the unique properties of Water.

Opener:  Why does ice float.

Summary: What is the difference between adhesion and cohesion.Opener

  • Formative quiz over Bohr models of atoms, molecule, and structural models.
  • Discuss 2.2 (click here for a link)
  • Explain pH. (discuss the relationship between the H+ and OH-)
  • H.O. 2.2 worksheet
  • Assign 2.3 to read.(click here for the link)

Wednesday, Oct. 24

Lesson Objective:  I will learn about the 4 macromolecule groups that are found in living things.

Opener:  What does protein have that lipid or carbohydrates do not?

Summary:  The atom, phosphorus, is found in the molecule phosphate, explain why this molecule is so important to Nucleic Acid.

Thursday, Oct. 25

Lesson Objective:  I will learn the vocabulary that describes chemical reactions.

Opener:   What keeps our bodies from burning as we “burn” sugar to give us our energy needs?

Summary:  Please explain in a paragraph the relationship of a substrate and an active site.

Friday, Oct. 26

Lesson Objective:  Demonstrate that I understand how molecules of life are made and how they interact with each other. 

Opener:  I feel that I have prepared well for ____ of  this summative exam.  I will ask a fellow student to explain an area that I do not feel as comfortable.

Summary:  Explain in a short paragraph how you think you are making progress as a student.

  • Hand back worksheet 2.3
  • Summative exam over Chapter 2
  • Assign to read 7.1(click for a link)
