Lagonoy South Central School Lagonoy Camarines Sur S/Y 2021-2022 Detailed Lesson Plan in Science 4
I. Objectives
At the end of the lesson, the pupils should be able to:
a. Identify the different interactions among living things;
b. Realized the importance of interactions among living things; and
c. Illustrate understanding on the differenct interactions among organisms.
What is living things? Living things are those Which have life
like human, animals, and plants.
How about Non living things? non living things do not have life like the
material things around us, the phone,
chair, ballpen etc.
Very good! so since you already
understand the concept of the previous
topic, let’s move on to the next lesson.
Engagement
I have here a set of pictures and you are going
to identify the organisms that you can find in
each environment.
Picture 1
Ok very good!

ENGAGE
.
EXPLORE
Now you are going to perform a group
activity. You will be group into two, and
every group has their own task. Group 1
will be working on Activity 1 current and
voltage on pp 55-58, group 2 you will be
working on activity 2 voltage and
resistance on your module pp 58-60. The
objective of the activity is to understand
how do voltage and resistance affect
electric current. I will give you 10 minutes
to do the activity, after that you are going
to present the result.
Procedure:
1. Construct a simple ciruit using a dry
cell, a bulb, a switch and an ammeter.
Close the circuit by turning on the s
Switch. Observe the bulb and the
ammeter. Record the ammeter reading in
Table 1. Upon completion of the task,
switch off the circuit.

Group 2 Task
Activity 2 Current and Resistance
Materials needed:
1 ammeter
2dry cell holders
1 switch
3 bulb holders
2 dry cells
4 connecting wires
3 flashlight bulbs (voltage rating of
2.5 each)
Procedure:
1. Construct a simple circuit using 1 bulb,
2 dry cells and an ammeter as shown in
Figure 7. Record the electric current
measurement in Table 2. Once the task is
done, turn off the switch.
(After 10 min.)
Explain
On the activity given, any representative
from theGroup can present the result of
your activity.
Lets start with the group 1. This is the result of the readings based
on activity.
Table 2
Elaborate
What happens to the voltage as the no. of dry The voltage also increases.
cell increases?
What happens to the current as the no. of dry
cell increases? The current also increases
When the voltage increases, what happens
to the current? Increases or decreases? The current also increases
Now, how will you relate the current and voltage? As the voltage increases, the current
also increases
Exactly. When voltage increases, the current also
Increases. They are directly proportional to each other.
How does the brightness of the light indicated?
The brightness of the light indicates the amount
of electricity. The brighter the bulb, the higher the
Amount of the current.
Did you get it? Yes ma’am!
So let’s analyse table 2,
What is the ammeter reading in 1 bulb circuit having
two dry cells? 0.3 A
What about ammeter reading in 2 bulbs circuit with
the same no. of dry cell? 0.25A
What about the ammeter reading in 3 bulbs circuit
with the same no. of dry cells? 0. 2 A
Evaluation
Extend
Materials needed:
For circuit A
3 connecting wires
2 identical bulbs with holder
2 dry cells with holder
For circuit B
4 connecting wires
2 identical bulbs with holder
2 dry cells with holder
