This lesson plan introduces students to the concepts of substances and mixtures. It includes learning objectives, content, procedures, evaluation, and assignment. Students will be able to identify substances and mixtures, provide examples of each from home, and demonstrate how they are formed. The teacher will motivate students by relating the concepts to unity and diversity among people. Students will observe mixtures being formed, discuss the particle theory of matter, and present in groups on substances and mixtures.

1. A Semi-detailed Lesson Plan
in Science and Technology 7
Prepared by: Henry B. Sergio Jr.
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 variable materials in the community
for specific purposes.
Week: 4, Day: 1

Through a vertical
bullet list about
substances and mixtures,
the students should be

a pure substance or a
mixture;
B. share to the class
through recitation some
common substances and

formation of substances
and mixtures in group
presentation.

1. Pre-Assessment
a. Tell the class to bring out a ¼ sheet of pad
paper.

On a short bond paper
with 0.5 inches on all
sides as margin, make a
collage of the different
examples of mixtures and
substances that we see at
the environment. To be
passed on Friday,

“We are the world, we are the children. We
are the ones who make a brighter day so
let’s start giving. There’s a choice we’re
making, we’re saving our own lives. It’s
true we’ll make a better day just you and
me.”
In what way should we act as humans? What
does it mean by being one?

2. composed of only a
pure element.
2. A mixture is
composed of two or
more substances or
mixtures or
combination of both.
E. Skills
1. Identifying mixtures
from substances.
2. Demonstrating the
formation of mixtures
and substances.
F. Values
We live in a world full
of different people,
diverse with culture,
beliefs, race, color and
ideas.
We should act according to the norms
of our society and not merely on our
own will. Being one means there’s no
one on top but it is a congregation of
all from different place, race, gender,
religion, social status and skin color.
3. Process the answer of the students.
Human behavior is largely constrained by the
rules that govern particular situations and
environments. We are constantly obliged to
behave in a particular way, or to avoid certain
behaviors. These rules may be formal
regulations such as laws, or they may be
informal rules of 'social etiquette', which are
not written down but are implicit within the
situation itself.
Being one teaches us unity and unity teaches
us that we are composed of not just one but
variety of members. This leads us to our
lesson which is Mixtures and Substances.

3. B. Presentation
1. Show to the class a cup of glass with water. Call
on a student to describe the water in the glass and
what the water is made up of.
The water is crystal clear. It is made up of
hydrogen and oxygen.
2. Add the ½ teaspoon of powder mango juice to
the cup of water then stir it. Call another student to
describe now the combination of water and powder
juice.
The combination resulted to a yellowish liquid
made of water and powder juice.
3. Through a vertical bullet list, explain to the
class the difference of a mixture and a

4. solution.
Pure substances
• contains only one type of particle.
• Substances don't usually occur in
their pure form in nature, so in order
to obtain pure substances, people
must refine raw materials.
• Examples: Gold, water, lead etc..
Mixtures
• Mixtures are substances that consist
of combinations of two or more pure
substances, or different particles.
• Mixtures can be in the form of solids,
liquids, and/or gases, in any
combination.
• Examples: Air,concrete, juice etc.
Examples of Substances
Lead Gold

5. Water
Examples of Mixtures
Air Juice
Concrete
4. Post on the board two pictures about the
formation of Mixtures and Substances.

6. What can you say about the pictures?
Substances are formed
from only 1 particle
whereas mixtures are
formed from 2 or more
substances.

7. 5. Discuss on the Particle Theory of Matter.
Particle Theory of Matter
The Particle Theory of Matter states that:
Matter is made up of tiny particles (Atoms
& Molecules)
*Medial Assessment
Call randomly students to answer the following
questions.
What is mixture? What is a substance? Give
an example.
Substances are made up of a material that is
composed of only one type of particle;
examples of a pure substance include gold,
oxygen and water.
Mixtures are materials made up of at least
two different pure substances.

8. C. Generalization
1. Group the class into 5
groups with 10 members
2. Each group must come
up with a presentation
about how mixtures and
substances are formed
using only the members
3. They are given 3
minutes each only to
D. Application
each.
of the group
present.
From the given examples of known things at home,
a student picks one and share to the class if it’s a
substance or a mixture and what composes it.

9. *Final Assessment
I choose water. It is a
substance. It is made up of the particles of
water which is hydrogen and oxygen.

10. Are the following
substances or mixtures?
Gold, concrete, water
Gold is a substance.
Concrete is a mixture.
Water is a substance
