these changes are very noticeable while
others are not.
Today you will do an activity that will
help you understand how materials
undergo changes.
14. 1. blow into the balloon. Tie
the end to keep the ballon in
shape. Observe the size of
each balloon before and
after blowing.
2. Cut the uncut piece of bond
paper into different shapes.
Observe what happens to its
sizes.
3. Light the candle and put it
into a bottle to secure it in
place. Observe what
happens to the candle. Then
put off the flame.
17. Experiment Questions:
1.What do you noticed with the size and shape of the
balloon after blowing?
2. What happened to the paper after cutting it in different
shapes?
3. What have you noticed with with the candles while
lighted?
4. What condition that made it changed?
19. Which of the following shows physical change, put a check
before the number.
______1.boiling of water ______6.burning of rubber
______2.ripening of fruits ______7.breaking of rocks
______3.cutting firewood
______4.mixing water and ice cube
______5.souring of milk ______8. melting
of wax

Editor's Notes
Before we will proceed, what are the things we need to remember while the class is going on?
We should still wear our mask
This time we will see if you still remember something from our previous lesson. So we will play a game Spin the Wheel game.
So this time I will show you a real objects here and you will name each depends on what will I show to you. So are you all ready?
This time let’s see if you could still remember some of the details from our previous lesson and we will play a game called Pick a food.
Did you enjoy the game? This time we will watch a video but before that let’s guess the hidden words.
- PUT THE IM’S on the board
Did you enjoy the game? This time we will answer the following words.
- PUT THE IM’S on the board
So since you already create a word form it. Here are the meaning of the words.
MOTIVATION: Have you been to a city?What places you been to in a city like Kidapawan.
establishment that provides lodging and usually meals, entertainment, and personal services for its guests. Do you know this hotel can be found here in North Cotabato? Yes we can found this before in Kidapawan Cit, why before? Because currently this hotel is not there anymore. Do you know what happen?
Here it is before and after the earthquake hits our nearby municipalities this is what happen. Now let’s compare the photos. Can someone tell me what changes have taken place in this particular place? Answer: the hotel was damaged, it change physically, there are debris, it is now dangerous to get near because of fallen materials.
4. How we are able to take care of our environment?
5. How to be prepared when natural phenomenon hits?
That’s a great observation.
Today we will explore. I will group you into 4 groups but before that these are the group expectation.
Great! So can you do that? I will expect you to do so.
Here is the rubrics to follow for our Group Experiment:
Prepare the flask or the task card.
.
You need to choose a leader scientist of your group and the scientist leader will proceed here in front for you to get your flask and inside Are you all ready? Great! Now let’s get started.
May I remind you as well to be extra careful in performing the task especially you will be using a hot water.
