B. Performance
Standards
The structure of biomolecules, which are made up mostly of a limited number of
elements, such as carbon, hydrogen, oxygen, and nitrogen.
The learners shall be able to:
Using any form of media, present chemical reactions involved in biological and
industrial processes affecting life and the environment

For the recall of the lesson, students will be asked the following questions;
Elicit
A. Reviewing
previous lesson or
presenting new
lesson
Engage

What are the two changes in matter?
What do you know about Physical change? Chemical change?
Who can give an example of chemical change?
What do you think will happen during chemical change?
The students will be given examples of changes in matter all they have to do is to
identify whether it is a physical or chemical change.
1. Burning of wood (Combustion Reaction)
--methane combined with two oxygen ion yields to form carbon dioxide
and two molecules of water (CH4 + 2O2
CO2 + 2H2O)
2. Melting of Ice
3. Rusting of Iron
Four Iron combined with three molecules of oxygen and six molecules of
water yields to form Iron III hydroxide (4Fe+3O2 + 6H2O
2Fe(OH)3
4. Paper cut into pieces
Based on the examples of chemical reactions on the first activity, students will be
asked to identify the reactants and the products.

There are symbols used in writing chemical equations:
Table 7. Symbols and their Meanings
Symbol
+
(s), (l), (g), (aq)
Meaning
To show
combination of
reactants or
products
To produce; to
form; to yield
(s)-solid, (l)liquid, (g)-gas,
(aq)-aqueous
(substance is
dissolved in
water)
Reversible
reaction
Indicates that
heat is supplied
to the reaction
A formula written
above or below
the yield sign
indicates its use
as catalyst or
solvent.
Using the symbols and formulas in Table 6 and the symbols in Table 7, write the
chemical reaction using these symbols to complete the chemical equation.

2. How can you determine the reactants and the products in a given chemical
reaction?
3. How do you write chemical equations?
Elaborate
F. Finding
practical
applications of
concepts and
skills in daily
living.
G. Making
generalizations
and abstractions
about the lesson.
Evaluate
H. Evaluating
learning.
Guided Questions:
1. What is chemical reaction?
Chemical reaction is a process in which one or more substances, the
reactants, are converted to one or more different substances, the products.
2. Chemical equation?
Chemical equation is an equation that uses chemical symbols and
formulas to represent a chemical reaction.
3. What are reactants and products?
Reactants are the substances that enter into a chemical reaction, and
products are the resulting substances.
Direction: Write the letter of the correct answer.
1. A chemical change is different than a physical change because in a
chemical change
A. Chemicals are used.
B. Molecules do not physically touch.
C. A new substance is formed and in a physical change no new substance
is formed.
D. Some atoms disappear while others multiply to form the products.
2. In writing a chemical equation, a
sign means?
A. Reversible reaction
B. To produce or to form
C. To show combination of reactants or products.
D. To indicate heat
3. A chemical reaction is a process in which?
A. All reactants change state
B. Products change into reactants
C. The law of conservation of mass applies
D. All of these
4. What are the products in the equation below?
