Lesson Plan in ScienceGrade V

I. Objective:at the end of the period, the pupils should be able to:1. describe changes happening in a certain matter2. compare the characteristics of physical change and chemical change3. classify the changes happened to the object, if it is physical or chemical change4. show willingness to help each members on assigned group activities

II. Subject Matter:Changes in Matters

Values: Being observant to the changes happening in our EnvironmentIII. Materials:

ChartVisual AidsParaphernalia (variables)

- Matches- Papers- Pieces of the matches’ part- Burned match- Cut papers- Burned papers

IV. Procedure:A. Motivation:

Teacher’s Activity Pupils’ Activity

Good Morning!

Please observe your surroundings and any pieces of mess you see put it on the trash, and aligned your chairs properly.

Very Good! You may now be seated.

Last week we discussed all about matter. May I know who can recall what matter is?

Good Morning Sir!

(picking pieces of paper or any dirt and aligning the chairs)

(pupils will be on their seat)

Student#1: matter is anything that has mass and

Another?

Very GoodPlease give them 3 claps

Before we start to our lesson today, I would like to group you in to two (2). First group are on my left side and the second group will be on my right side. You may now group yourselves while you are singing “The more we get together...” and simultaneously make a wide circle on your group’s place.

I have here samples of two object converted into two different forms.

I would like you to observe changes happened by comparing it in terms of size, color and texture.

Understood?

In group one,the task will be Matches on its original composition, Burned and Broke into pieces.

In group two, will be Papers on its original composition, Burned and Tear into pieces

You may start now!

takes up space

Student#2: Matter is anything, such as a solid, liquid or gas that has mass and occupies space.

(uniting every group will singing “The more we get Together”)

“The more we get together, together, together. The more we get together the happier are we.And your friends are my friend and my friends are your friendsThe more we get together the happier are we.”

(Listening)

Yes, Sir!

(Starting their work and sharing Ideas)

Answer to the group activity

characteristics Group 1 Group 2Matches Paper

Break into pieces Burned Tear into pieces Burnedsize smaller than to

the original sizepowdered or transformed into its smallest formor it became ashes

smaller than the normal paper

ashes-like size

color same color from its the original

color black same as the original color black with the touch of gray

texture same as the original rough

rougher same as the first object smooth

easily tear

Okay, Time is up.Please stop writing and post all your work on

the board.

Choose two representatives to explain what you have observed.

Very Good.Please give Group 1 an ANGEL CLAP.

Very Good also.Give Group 2 an OISHI CLAP.

(every group will post their works on the board)

Group 1 Rep.:The matches that broke into pieces have smaller size compare to its original form but same color and texture. On the other hand, the burned matches are very far from its characteristics in terms of size, color and texture from the original. It gets powdery, color black and rougher.

(Clap) 1 2 3(Stamp your feet) 1 2 3(make a Halo) Angel...

Group 2 Rep.:The papers were cut into pieces but also same color and texture as the original. But, on the burned papers it became ashes. Color black and when you hold it, it easily destroy.

(Clap) 1 2 3(Stamp your feet) 1 2 3Oishi...

B. Presentation:

You all have very good answer and your answers are much closed to each other but different variables.In Group One, Matches and in Group Two Paper.

A while ago, two of your classmate defines what matter is, and one of them answer that matter has its states.Who can give me one state?

Another? yes

and last one.

(Listening)

Student #1:Solid

Student #2: Liquid

Student #3: Gas

Very good, please give them 4claps

And matters may also change.

Changes in matter may occur when a force or energy applied in an object.For example (get a piece of paper)I will tear this paper into pieces.

What changed did you noticed?

Very good. The size, it became smaller than the original

And Why do you think so?Very well said

I tear it with my two hands, it will never be tearing into pieces until someone or somebody will do right?

How about the lighted matches, what changed did you noticed?

Okay another. How about the color?

Very good, and last

Very Good pupils.Give yourselves a YES CLAP.

What we did earlier (Matches and Papers activity) undergo changes,And may be classified into Physical or Chemical change.

Class: 4x clap

(listening)

Student#1: it became smaller.

Student#2: because you exerted force for it to be transformed into pieces.

Student#1: it became ashes

Student#2: the color became black

Student#3: became rougher because of its size.

(Clap) 1 2 3(Stamp your feet) 1 2 3YES...

Physical Change Chemical Change- An object may change in form but

not in the kind of molecules it has- The molecules of an object changed into another kind of molecules and a new substance with new properties

is formed.

Examples: logs changed into wood chipsa fruit sliced into piecesbig rocks change into small rockswater change into iceice or water into water vapourice into watertear paper

Examples:rust in ironsburned objectspoiled food

When we say Physical Change, the internal make-up of the object (molecules) stays the same, even after the change — only its form changes.Just like the paper I tear into pieces. Only the size and shape changed but not its internal component.

Physical Change is also called Reversible change where in the resulting element can be opposite into the object before. Changes that can be reversed.

Take a look at this change.

(Listening)

(Listening)

Student#1: Solid

What state of matter the ice is?

Very good.

And we all know that when we put the ice into a hotter place it melts. But the composition of the ice is the same as the water, only that it changes it form. Understood?

Do you think we bring back the water into its earlier form? How?Okay Very Good.

And when we say Chemical Change, the internal make-up (molecules) of the object changes.Unlike a physical change, chemical changes cannot be reversed. Changes that cannot be reversed are called Non-reversible Change. We cannot bring it back to its original form.Every day, we experience chemical changes in many things around us.

How about you.

What you have noticed to the burned matches from activity.

Okay, you may be seated.

Think of the dry wood in the fireplace. When we

Class: Yes.

Student #1: Yes, we can put it on the colder place such as refrigerator.

(Calling the student to stand up and answer the question)

Student #1: it became ashes when lighted, the color is different to the original and its texture is rougher.

(Listening)

Class: Yes Sir.

light the wood up, it burns gently and after a while it turns into ashes. As it burns, it produces heat, light and smoke which escapes through the air. The heat, light, fire and smoke are all good characteristics of a chemical reaction, which result in a completely new matter—ashes. Note that the ashes from the burning wood have an entirely new molecular composition. It can never be turned back into wood again.Understood?

Okay here are the other example of Physical change

Physical Change

Sliced Fruit (Papaya) Logs into woodchips

And on the other hand, the Chemical Changed

Chemical Change

Who can give me other examples in Physical Change?

Very Good, Another?

Okay, good.

How about Chemical Change.

Excellent. Last one.

Wow, very excellent.

Student #1: blended fruits

Student #2: crumpling paper.

Student #3: spoiled milk

Student #4: digesting food.

C. Application:

I have here an activity that you will be answering together with your groups.

You will go in front one by one and give examples on the following changes we tackled. Alternately give example on the Physical Change and Chemical change.Understood?

(Listening)

PHYSICAL CHANGE CHEMICAL CHANGE

D. Evaluation:

Okay time is up. I will check every group’s answer and tomorrow will be receiving a points.

Any question?

If there is no question please get your notebook and answer this seatwork.

(Students may ask or may not)

(Students will get there notebook)

Directions: Analyze the following changes in matter. If the change in matter is Physical Change put “PC” and if it is Chemical Change put “CC”. Write your answer in the space provide before the number.

____1. Spoiled food ____6. Ignited matches

____2. Tear paper____3. Water into Ice____4. Burned wood____5. Logs into woodchips

____7. Rust in irons____8. Cut garments____9. Dried leaves____10. Sliced fruits

E. Closure:

Okay time is up.

Exchange paper with your seatmate and we will check it.

(GIVING THE ANSWER)

Okay. Pass your notebook and I will record it.

Okay. (Posting the Closure)

To be able to verify you understood the topics today please complete the sentence.

I learned that...
