Tuesday Today’s Agenda UNIT TEST Complete the Chemical vs. Physical Changes handout.
-Reading: Chemical Reactions and Equations -Parts of a Chemical Equation (RM52) -Name That Part! (RM53) -Law of Conservation of Mass (RM61) -Chemical Storytelling
NEXT WED/THRS (Oct. 23 & 24) V: 0
Reminder: Enter the classroom, begin the Do Now immediately, silently and independently.

TEKS
8.5 (D)
Recognize that chemical formulas are used to identify substances and determine the number of atoms of each element in chemical formulas containing subscripts
8.5 (E)
Investigate how evidence of chemical reactions indicate that new substances with different properties are formed
8.5 (F)
Recognize whether a chemical equation containing coefficients is balanced or not and how that relates to the law of conservation of mass.

ESSENTIAL QUESTIONS:
- How does the structure of matter affect its identity and properties?
- How do we describe and classify matter?
- What happens to atoms in a chemical reaction?
- What is the difference between physical and chemical changes?
- What are the signs that a chemical changes has occurred?
DAILY OBJECTIVES:
Students will identify the number of elements and atoms in a chemical formula and will be able to determine if a chemical equation is balanced or not.

Law of Conservation of Mass: V: 3

Law of Conservation of Mass (RM61)
Law of Conservation of Mass: Matter is not created or destroyed in a chemical reaction.
V: 3

Law of Conservation of Mass (RM61)
Law of Conservation of Mass: Matter is not created or destroyed in a chemical reaction.
V: 3 The number of atoms in the Reactant must equal the number of atoms in the Product.

Law of Conservation of Mass (RM61)
V: 0 Complete RM 61.
1. Count the number of atoms for each element on the Reactant side.
2. Count the number of atoms for each element on the Product side.

Mass Observations
V: 2

V: 2 1.
Create an aluminum foil “boat”.
2.
3.
Put ½ of a spoonful of sugar in your “boat”.
Find the mass of the sugar and “boat”.
4. Record the mass and observations in the Before section of your data table.

V: 2 5. Light the candle at your table.
6. Place your sugar boat over the flame.
7. Once the reaction is complete (all the white sugar has changed), blow out the flame.
8. Find the mass of your sugar boat.
9. Record the mass and any observations in the After section of your data table.

Was the mass Before and After the same?
V: 2

V: 2 Was the mass Before and After the same?
The Law of Conservation of Mass says that matter is not created or destroyed in a chemical reaction. How, then, could the mass before and after applying the heat be different?
