Housekeeping:  Any outstanding matters we need to deal with?  Ladies without laptops at this point will start to get the side-eye from me.  The side-eye is a visual, silent way of me saying "I don't want to hear your excuses."  You know how we roll in my class by now.

Lesson Review:   Socrative   Teacher Room Code: LR2E0KJH

Lesson Objectives: 
1. Deconstruct and explain the components of a chemical equation.

2. Understand the difference between reactants and products.
3. Explain what state symbols are and how they are used in a chemical equation.
4. Determine how to balance a chemical equation.
4. Solve conservation of mass in chemical equations.

Content Review: 
Weebly Links:  Particulate Nature of Matter   Chemical Reactions

Textbook Readings: Ch 1; p. 3-14

Student Missions:

Mission 1:  Breaking it Down, Atomic Style.  I will show you some chemical equations and we will deconstruct them.  Here are some notes to get you started.  Don't worry; we're just tackling the first page.

State symbols are used in chemical equations to denote the physical state of the substances before and after reacting.  The BBC has a nice little Bitesize denoting all four state symbols.  Be sure you know how to write them and what they mean.

Mission 2: BALANCE, BABY, BALANCE!!!  The Law of Conservation of Mass says that mass is always conserved.  So what does this mean for chemical reactions?  It means adding atoms and ions, of course.  We need a worksheet to practice with, so I have provided one.

Mr. Causey is always down for the cause.
9/3 Homework:  Complete the handout.

Mission 3: Phasing In, Phasing Out!  You know the basic three states of matter.  Did you know they could change into one another?  Take a look at this graphic and try to explain what you're seeing using water as your example. Which set of triangles represent endothermic changes (energy absorbed)?  Which set of triangles represent exothermic changes (energy released)?
