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.

IV. Evaluation IV. Assignment

Through a vertical

bullet list about

substances and mixtures,

a pure substance or a

mixture;

B. share to the class

through recitation some

common substances and

mixtures seen at home ;

a. Tell the class to bring out a ¼ sheet of pad

paper.

b. Ask them to define Substances and Mixtures

and give 2 examples each.

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

“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?

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.

3. Process the answer of the students.

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.

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.

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.

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.

3. Through a vertical bullet list, explain to the

class the difference of a mixture and a

The water is crystal clear. It is made up of

hydrogen and oxygen.

The combination resulted to a yellowish liquid

made of water and powder juice.

solution.

Examples of Substances

Lead Gold

• 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..

Pure substances

• 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.

Mixtures

Water

Examples of Mixtures

Air Juice

Concrete

4. Post on the board two pictures about the

formation of Mixtures and Substances.

What can you say about the pictures?

Substances are formed

from only 1 particle

whereas mixtures are

formed from 2 or more

substances.

5. Discuss on the Particle Theory of Matter.

*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.

Particle Theory of Matter

The Particle Theory of Matter states that:

Matter is made up of tiny particles (Atoms

& Molecules)

C. Generalization

D. Application

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.

1. Group the class into 5

groups with 10 members

each.

2. Each group must come

up with a presentation

about how mixtures and

substances are formed

using only the members

of the group

3. They are given 3

minutes each only to

present.

*Final Assessment

I choose water. It is a

substance. It is made up of the particles of

water which is hydrogen and oxygen.

Are the following

substances or mixtures?

Gold, concrete, water

Gold is a substance.

Concrete is a mixture.

Water is a substance
