2. CLASSROOM PROMISES
I promise to foster a respectful environment by
treating my classmates and teacher with kindness
and courtesy.
I promise to actively participate in all
classroom activities.
I promise to embrace the joy of learning, approaching
every task with enthusiasm and a positive attitude.
I promise to be an attentive listener when someone
is speaking in front of the class
I promise to willingly share my thoughts and
ideas during discussion.
3. Direction: In this game,
statements related to the
previous topic will be presented.
When a true statement comes up,
shout 'Pak na pak.' But if the
statement is false, confidently say
'Blap na blap.
17. Objectives:
At the end of the lesson the students should
be able to:
1. Explain what is Boyle’s Law
2. Demonstrate the relationship between
volume and pressure at constant pressure of
gas
3. Relate the importance of Boyle’s Law in
real life scenario
20. Directions:
1. Place the marshmallow just inside the large opening at
the back of the syringe
2. Cap the syringe
3. Hold the cap on, and push the plunger in slowly.
4. Release the cap and push the plunger into the
marshmallow
5. Pull the plunger back again, and move the marshmallow
into the middle of the syringe.
6. Release your finger from the tip of the syringe
21. Guide Questions:
1. What happen to the size of the marshmallow as
the plunger being press and released?
2. How do you describe the volume of the
marshmallows inside the syringe as the pressure
increases and decreases?
3. Relate this demonstration to the definition of
Boyle's Law. How did this demonstration verify the
accuracy of that law?
28. Another is aerosol cans
contain gas under
pressure. When the
nozzle is pressed, the
pressure inside the can
decreases, causing the
gas to expand and push
the product out of the
can.
29. Another application of
Boyles Law in our daily life
is when you inflate a
balloon, you are increasing
the volume of the gas cally
air) inside it. According to
Boyle's Law, as the volume
increases, the pressure
inside the balloon
decreases.
30. These are just a few
examples of how Boyle's
Law is applied in everyday
situations.
31. Direction: Read carefully each item. Write only the letter of the correct
answer for question.
1. Which of the following needs to remain constant when using the
Boyles law
a. energy b. pressure c. temperature d. volume
2. When the pressure on a gas goes up, what happens to its volume
a. Decreases b. increases
c. decreases then increases d. stays the same
3. When the volume of gas goes down, what happens to its pressure
a. Decreases c. decreases then increases
b. increases d. stays the same
4. What relationship can be derived between pressure and volume
a. the volume is directly proportional to pressure
b. the volume is insignificantly related to its pressure
c. the volume is inversely proportional to pressure
d. the volume is inversely proportional to pressure to the square of its
pressure
5. Space occupied by the liquid and gases
a. temperature b. pressure c. volume d. mass

Editor's Notes
Before we officially start our class, kindly read our classroom promises aloud, Always keep these promises and not break them, okay?
Because promises are not meant to be broken.
Very good everyone, this only shows that you have learned a lot last meeting. With that give yourself an aghamazing clap.
Anglo Irish Natural philosopher, Chemist and Physicist Robert Boyle who was born on the year 16277 and died on year 1691. Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method.

It's a fundamental principle in understanding the behavior of gases and is widely used in various fields including chemistry, physics, engineering, and environmental science.
