E. Activity
Getting To Know Gases
1. The class will be divided into 3 groups.
2. The activity has three parts and each group will be given different sets to perform in the
said activity.
3. The first group will be assigned to the first set of the activity, the second group will
perform the second part and lastly the third group will be assigned to the third set of
the activity.
4. In set A, the teacher will provide the following materials: 2 ordinary balloons with the
same size, hanger, cord/yarn, needle and a balloon pump.
5. In set B, the teacher will provide the following materials: 3 transparent Cups, Paper
Towel/Tissue, Water, Bowl, and Scotch Tape.
6. In set C, the teacher will provide the following materials: Plastic bottle, Paper, Rubber
band and a Straw
7. Each group will be provided a manila paper, marker and an activity sheet that contains
the procedures and questions (to be answered by the group) provided by the teacher.
8. The students will perform the task to observe and answer the questions provided by
the teacher in the activity sheet.
9. The students are given 20 minutes to finish the said activity.
10. After observing and answering the questions each group will choose a
representative (at least 2) to perform the given task and explain/present their outputs
(observations, answers, conclusions) in the class.
11. Each group will be given 5 minutes to present their outputs.
12. They will be graded according to this criteria:

activity.
F. Analysis

How did you find doing our activity?

Post all your outputs on the wall.

Each group will have a representative to present and explain their output.

Why do you think you were similar or different?

Did you learn something from the activity?
G. Abstraction
What is matter?
 Matter is anything that occupies space and has mass.
What are the three phases of matter?
 Solid, Liquid, and Gas.
What is gas?
 Gas is found everywhere. It enters/leave our body everyday every time we inhale and exhale.
Jan Batista Van Helmot derived the term from the Greek word “Chaos”, which means
formless mass.
Behavior of Gases:
4. Expansibility – is the property of gases to increase the spaces between its
molecules if the temperature is increased. Example: Hot air balloon
5. Compressibility – it is the ability to compress if the temperature is decreased.
Example: An inflated balloon reduces its size when put inside the cooler.
6. Diffusibility – gas ability to diffuse or intermingle with the molecules of other
substances. Example: The odor of your neighbor’s fried fish reaches your home.
Properties of Gases:
5. Mass – the amount of gas. Could be expressed in moles or grams. The mass of
gases is negligible.
6. Volume – is the amount of space occupied by the gases.
7. Temperature – is the measure of the hotness or coldness of an object.
8. Pressure – is the average effect of the forces of the colliding molecules.
H. Generalization
 Gases have different behavior and properties that we can relate to our daily living. Even though
gases can’t be seen by our naked eyes still, it is important for gases to coexist with all living
things.
I. Application
 How would you use your understanding about the behavior and properties of gases in your
daily lives? Can you use it while you are cooking? Answers will vary.
J. Assessment
Direction: On your ¼ sheet of paper, write the correct answer on the following statements:
1. Volume is the amount of space occupied by the gases.
2. Mass can be expressed as mole/grams.
3. Temperature is the measure of hotness or coldness of an object.
4. Matter is something that occupy space and has mass.
5. Compressibility is the ability to compress as the temperature is decreased.
6-8. What are the phases of matter? Solid, Liquid, and Gas
9. Diffusibility is the ability to intermingle with other substances.
10. Expansibility is the ability to expand its size when temperature is increased.
Assignment
 Study in advance about the gas laws.

Activity1
Getting To Know Gases
A. Gases and Its Mass
Materials:
2 Balloons with the Same Size
Hanger
Cord
Needle
Balloon Pump
Procedure:
1. Inflate the two balloons then close it.
2. Tie the balloons on each end of the hanger with the use of a cord.
3. Put the hanger on somewhere where it can hang on its own. (NOTE: Watch out for any air
disturbances it may lead to false results.)
4. Observe what happens.
5. Using a needle, prick the balloon near its end where it was closed.
6. Observed what happens.
Questions:

2.
Which is heavier, the inflated or the deflated balloon? Why?
3. 3. What can you assume in this activity?

Paper Towel/ Tissue
Water
Bowl
Scotch Tape
Procedure:
1. Label cup A, B and C.
2. A cup with a paper towel is tape inside.
3. Pushed upright, open and up into the bowl of water until the water is above the rim of a cup.
4. Observe what happens.
5. B cup with a paper towel tape inside.
