I. OBJECTIVESAt the end of 60 minutes period, 75% of the students must be able to:

define the term “pressure” in terms of force; understand the relationship of pressure to area and force; and solve the problem in getting pressure involving force and area.

II. LEARNING TASKTopic: Pressure

Concepts:

Pressure is defined as the force F per unit area A, so P=FA

Pressure therefore has unit of N/m2 = kg m¯1 s¯2 it is usually denoted P or p. Pressure can be measured in atmosphere, bars, inches or mercury, millimeters of mercury, Pascal or torr.

F is the force= NA is the area in square= m2 meterP= Pressure= Pa

One N/m2 is given a special name, Pascal (Pa), in honor of Blaise Pascal, who did considerable studies on fluid pressure.

B. ReviewWhat is thermodynamics?What are the laws of thermodynamics?

C. MotivationThe teacher will show pictures to the students and ask the students to

describe what they see.

D. Lesson ProperActivity

Pre-discussion ActivityThe students will be group by 6, each group should have foam, and

bottled water.The students will perform the activity.The teacher will discuss the topic based from the activity.

Activity ProperProblem Solving

The teacher will give some problems involving pressure, force and area.The teacher will ask some students to solve the problems.

Post-Discussion ActivityThe teacher will ask the students to give/cite some examples of

pressure they encounter in their life.

Analysis

TEACHER’S ACTIVITY STUDENT’S ACTIVITY

What is pressure?

What is the formula and unit for pressure?

What is the relationship between pressure and area?

Pressure is the force per unit area.

P= FA

= Nm2

=Pa

Inversely proportional

Abstraction

How force and area affects pressure?Give some examples showing the relationship of pressure to force and

area.

Application

All of us experience forces in our surroundings. Our bodies and the sea of air around us interact. Air, a fluid, exerts a big force on us. Yet, this force does not crush us because our bodies respond with an equal and opposite force.

IV. EVALUATIONIdentify the terms being described.1. It is defined as the force per unit area.2. A person who is the pioneer work with pressure.3. Force divided by area is the formula of ____.4. It is perpendicular to the given area.5. It is the unit of pressure.

Solve the problem 6-10. Find the pressure exerted weighing 188 N with an area of 18 m2.

V. ASSIGNMENT

Solve the following problems

1. Suppose the force exerted by the air on one face of a cube is 8820N. Each side of the cube measures 30cm. calculate the pressure on this face.

2. What will be the pressure if the force is equal to 80kg m/s2 and area of 12cm2?



I. OBJECTIVESAt the end of 60 minutes period, 75% of the students must be able to: define the term “fluid pressure”, understand the relationship of fluid pressure to density and height (deep);

and solve the problems involving the topic.

II. LEARNING TASKTopic: Fluid Pressure

Concepts:Water pressure used to describe the flow strength of water through pipe or

outer type of channel.The pressure is the same in all direction in a fluid at a given point. This is true

because of the characteristic of liquids to take shape of their container.Other effects of fluid pressure are motion, heating, and chemical effects, as well

as applications in the field of hydraulics and in aircraft. Fluid pressure from gravity is the weight of the fluid above divided by the area it is pushing on. The pressure under water increases with how deep you are. The equation for calculating pressure is Pressure= D*g*hWhere D is the fluid’s density, g is the standard gravity (9.8m/s2) and h s the depth of the object in the fluid.

The teacher will ask the students to answer the problem on the board.

Post-Discussion ActivityThe teacher will ask the question:Why fluid pressure is important to our lives?

Analysis

TEACHER’S ACTIVITY STUDENT’S ACTIVITY

What is fluid pressure?

Why does pressure of liquid is the same in all directions at a given point?

What is the relationship of pressure and the deep of the fluid?

Fluid Pressure is the term used to describe the flow strength through pipe or other type of channel.

Because of the characteristic of fluid to take te shape of heir containers

Directly proportional

Abstraction

When diving, what happens to the weight pressing onto our bodies?

Application

Fluid pressure is the reason that divers need to breathe air from tanks or high pressure hoses when they dive beneath the surface area of the sea.

Evaluation

Write T if the statement is correct, and write F if the statement is wrong.

1. Pressure in liquid decreases with depth.2. Pressure in liquid acts equally in all directions.3. The greater the density of the liquid, the greater the pressure at a certain depth.4. The equation in solving pressure in liquid is P=mαL5. Liquid is denser than air.

Problem Solving

6-10. What is the pressure in water at the base of 10m high dam wall? Pressure due to water= 100000N/m2.

Assignment

Give 5 situations involving fluid pressure.
