Detailed Lesson Plan in Science Grade 7

Teacher: JESSA C. DE ASIS Subject: SCIENCE

School: LA DICHA NATIONAL HIGH SCHOOL Quarter: FIRST

Grade: SEVEN Date: SEPTEMBER 21, 2023

I. Objectives

Content Standard: The learners demonstrate an understanding of the properties of substances that
distinguish them from mixtures.

Performance Standard: The learners should be able to investigate the properties of mixtures of varying
concentrations using available materials in the community for specific purposes.

Learning Competency: Distinguish mixtures from substances based on a set of properties

Objectives:
 Determine the purpose of separating mixtures.
 Demonstrate knowledge of simple techniques of separating mixtures.
 Appreciate the importance of using the methods/techniques in separating mixtures in our day-to-
day life.

II. Content:

Subject Matter:
Demonstrating of Techniques of Separating Mixtures

Integration: English: Learners will be using as their medium of communication in their reporting and
some queries and answers.

Values: The students appreciate the practical applications of the methods in separating components of
mixtures.

Strategies: 7 E’s Learning Model, Cooperative Learning, Learners will be using as their medium of
communication in their reporting and some queries and answers, Collaboration Learning.

A. Pre-liminary Activities
Good morning class! Good morning, Ma’am!
(The students will follow)
Everybody stand up, and let’s pray.
“Before you sit kindly pick up pieces of trash under your chair and
arrange your chairs properly.”
“You may now take your seats.”
“Who is absent today? As I call your name, say present.
Did you get it? Yes, ma’am!

III. Learning Tasks:

ELICIT (Access prior knowledge)

 Review
As a sort of review, who can recall our topic last meeting? (Student 1 will answer.)
Our topic last meeting was all about
the different separating techniques
we use to separate any mixtures.
Okay very good! So, what are the different separating techniques
(Student 2 will answer.)
that we use to separate any mixtures?
The different techniques that we use
in separating mixtures are: Filtration,
Okay very good! Decantation, Magnetism, Sieving,
Hand-Picking, Evaporation,
Who can define filtration? Decantation? Magnetism?
Distillation and Chromatography.
Chromatography? Distillation? Evaporation?

Okay it seems that you’ve listen very well in our lesson yesterday.
(Student’s will give the meaning of
each technique.)
To start with our topic for today, let me introduce to you the
objectives of our lesson.

 Determine the purpose of separating mixtures.

 Demonstrate knowledge of simple techniques of The students will read the objective
separating mixtures. of the lesson.
 Appreciate the importance of using the
methods/techniques in separating mixtures in our day-
to-day life.

So those are the objectives for today’s lesson.

ENGAGE (Get the students’ minds focused on the topic)

Say/Ask: Could you imagine class if the materials around us can no longer
be separated?

What do you think will happen to us?

Say: Today we are going to relate the benefits of separating
mixtures/materials to our life.
