IV. PROCEDURES
2. A. Reviewing previous
lesson or presenting the
new lesson
Reflect on the line “Like poles
repel, unlike poles attract”.
What are atoms made of? What
structures compose an atom?
Enumerate some properties of the
three subatomic particles. (Refer
to table 2 in LM p195.)
Present the Table #2: Some
properties of the three main
subatomic particles on page 195
What is an atom?
What are the different
subatomic particles of an
atom?
B. Establishing a purpose
for the lesson Rub a plastic covered notebook
vigorously against a hard object
and placed it over the head.
What happens?
If you rub a plastic straw with
tissue paper and place it near an
aluminum foil, what will happen?
Give one property of subatomic
particle. Which among them
contributes the most to the
overall mass of an atom?
Ask which among the three has
the highest value of mass.
Explain the concept of Scientific
notation.
(Show to the class a picture of
a raisin bread.)
Guide Questions:
1. What is the name of this
bread?
2. What is in this bread that is
not found in other breads?
C. Presenting
examples/instances of
the new lesson
D. Discussion of new
concepts and practicing
new skills #1
Essential Question:
Do objects attract or repel each
other/carry positive and negative
charges?
Essential Question:
Compare the masses of the
subatomic particles.
Essential Question:
How did Thomson discover the
electron?
E. Discussion of new
concepts and practicing
new skills #2
Perform Activity 1: “Charge” it to
experience! in LM p193.
Perform Activity 2: The big
difference in LM pp195-196.
(Show Thomson’s atomic
model and elicit ideas from the
students.)
F. Developing mastery
(Leads to Formative
Assessment 3)
Students present the results of
the activity.
Answer guide questions. (refer
to the activity)
Students present the results of the
activity. Comparison of the masses
of the three subatomic particles
using the bar graph, pie chart and
a seesaw can. Answer guide
questions. (refer to the activity).
Lecture:
Discuss the details of his
discovery.
G. Finding Practical
applications of
concepts and skills in
daily living Ask students what makes up an
atom? Give the charges of the
three subatomic particles.
Which subatomic particle/s
make/s up most of the mass of
the atom?
Key Questions:
1. What was the experiment
conducted by J.J. Thomson?
2. How was he able to prove the
existence of electrons?
3. Describe Thomson’s
discovery.
H. Making generalizations
and abstractions about
the lesson
3. I. Evaluating learning Direction: In ½ crosswise,
complete the table.
Direction: In ½ crosswise, answer
the following questions. (Refer to
the masses in table 2.)
1.Which subatomic particle is the
lightest?
2.Which subatomic particle is the
heaviest?
3. Which subatomic particle has
almost the same mass?
4-5. Which subatomic particles
make up most of the mass of the
atom.
Direction: In ½ crosswise, draw
your own version of Thomson’s
model and write a short
description.
