ENTRY BEHAVIOUR/ PREVIOUS KNOWLEDGE: the students are familiar with water projects.

WORD FILE:  colourless, odourless, tasteless.                 

             LESSON CONTENT

Air is a mixture of gases (especially oxygen) required for breathing. It is a colourless, odourless and tasteless mixture of gases. Air expands when heated.

 PROPERTIES OF AIR

1.  it has weight
2.  it occupies space and
3.  It is present everywhere.

PART OF AIR

AIR part consist of

1. Active air or Oxygen: Active air allows substance to burn. It is one fifth (20%) the volume of air.
2. Inactive air. It is about four fifth (80%) of air. It is more of Nitrogen.

PRESSURE

Pressure is the force applied to a unit area of surface; measured in pascals (SI unit) or in dynes (cgs unit).

WHY THINGS MOVE IN AIR (AIR AND PROPULSION)

Things moves around because of the pressure of the air. Like kite is a light object with large surface.so it is very easy to float with the pressure of air. Likewise also any light object with a large surface area can float easily with air pressure.

 USES OF AIR PRESSURE

1. It enable aero plane to fly easily on air.
2. It helps in the propulsion of rocket.
3. It help human when using parachute to land safely from air.
4. It helps some birds to stay in the air.
5. It helps birds when flying.
6. Wind mill (Turbine generator) used the wind by air pressure to generate electricity.

Air aid burning because air contain energy when you blow air over match stick, and its flame is put out, it means the active air around it is not enough. The inactive air, which forms the greater part of air. it is the part that helped put out the flame.

INSTRUCTIONAL PROCEDURE

• The Teacher revises the previous lesson (WATER PROJECTS).
• The Teacher introduces the lesson through question and answer (AIR).
• The Teacher explains the lessons.
• The Teacher write the note on the board.

LEARNERS ACTIVITIES

Learners participate in the class discussion

LESSON EVALUATION

Teacher ask the learners to:

• Identify the common characteristics of air.
• Demonstrate Air pressure on every object.
• Explain why things move in the air.
• State the special features of things that move or float on air.
• Mention instances of the application of air pressure to do work.

CONCLUSION: the teacher summarize the lesson.
