Lesson Plan

Period #1 Unit 1 Exam / Unit 2 - Atoms, Molecules & Ions

Materials : Textbook : Chemistry - Nelson

Review : Recall definition of Matter, and Element

Objectives : students should be able to :

2.1 describe a substance as having a set of unique and identifiable properties

2.2 classify a given material as an element, compound, or mixture, using the properties of the material

2.3 describe several ways that substances may be separated from one another

2.4 relate the observable properties and characteristics of elements, compounds, and mixtures to the concept of atoms and molecules

2.5 define atom, molecule, and ion

 

Part I - Atoms, Elements & Compounds - Introduction and Notes :

Students will take the first half of the class to write their Unit One Exam.

When finished the exam, students should begin to read chapter 3 in preparation for the next unit.

Give notes starting, "ATOMS, MOLECULES AND IONS", define matter, element, atom, molecule, metal and non metal on page 2-1, 2-2 of notes.

Differentiate between the theoretical and empirical definitions of elements and compounds.

Demonstration of Metals, Non Metals, and Metalloids

• set out a variety of elements
• students can observe various properties of the elements
• create a table on the board and examine the results
• do these elements fit our previous description of metals and nonmetals?

 

Give notes starting, "ION", on page 2-3, define ion, cation, anion, polyatomic ion.

Distinguish between ionic compounds, molecular compounds and acids and bases.

Explain how we use formulas as symbols for elements and compounds

Go over question 10, and 12 page 102 of Nelson

Part II - Ionic Compounds - Introduction and Notes

Give notes starting "NAMING COMPOUNDS" on page 2-6, 2-7 to discuss general rules and the naming of Binary Ionic Compounds.

Go through examples on pages 2-7, 2-8, writing names from formulas.

Do practice problems on page 2-9.

Give notes starting "IONIC BINARY COMPOUNDS", on page 2-11 to explain how to write formula given the name of ionic compounds.

Go through examples on page 2-12, 2-13 writing formula from names.

Do practice problems on page 2-14

Explain the "Cross Over Technique" for writing formula as shown on page 2-17 of the notes, and go through examples on page 2-17 and 2-18.

Give notes starting "BINARY COMPOUNDS OF MULTIVALENT CATIONS", on page 2-19 to explain how to write the name given the formula.

Example Iron + Oxygen give two products
