MEANING OF AIR AND AIR PRESSURE 

AIR

Air is everywhere on the earth, it is wind in motion.

 

When air is moving, it is called wind. Wind is air that is moving.

 

AIR PRESSURE

Air pressure is the weight of air above anything below it.

 

 

ACTIVITIES ON HOW AIR IS WIND IN MOTION 

Teacher’s instructions:

  • Cut a sheet of paper in pieces.
  • Blow or fan the piece of papers.
  • Ask pupils to observe and discuss their observation.

Pupil’s Response – The Air moved. If it doesn’t, the piece of papers will not be blown away.

Teacher’s remark – Listen and support the pupils and give a great cheer for active participation.

 

 

LESSON 2 – GROUP WORK ON PROPERTIES OF AIR

Group the pupils into 2 or more groups depending on the size of the class.

 

GROUP 1 – INSTRUCTIONS 

1. Weigh a deflated football bladder on a scale balance, take the weigh and write it down.

2. Inflate the football with air and weigh it again, take the weigh and write it down.

3. Compare the weights.

4. Which one is heavier?

5. What makes it heavier, if inflated ball is heavier?

6. What does this suggest to you?

Expected responses – Air has weight. 

 

GROUP 2 – INSTRUCTIONS 

1. Put a small bottle upside down into a basin of water.

 

2. Turn the bottle up side down and put inside the water. What do you observe?

Expected responses – Water cannot go in the bottle. 

3. Gently turn the mouth of the bottle toward the surface of the water. What do you observe?

Expected responses – Water can enter the bottle. 

4. Explain why water cannot enter into the bottle in the first instance.

5. Is the bottle empty after?

Expected responses – No, it is not empty. 

Conclusion – Air occupies space. For the water to enter the bottle, the air must go out. But if  the air cannot come out, water cannot enter. 

 

GROUP 3 – INSTRUCTIONS 

1. Inflate a balloon.

2. Touch it gently.

3. How does it feel to touch.

4. Release the inflated balloon in front of pieces of paper.

5. What do you observe?

Expected responses – Air pushes the pieces of paper away. Air can push anything about because it has weight and pressure. The weight of an object is force that push objects about. 

 

GROUP 4 – INSTRUCTIONS 

1. Inflated 4 balloons.

2. Put all the balloons together and place a flat plywood on them.

3. One of you should sit on it.

4. What do you observe?

5. What keeps the pupil afloat on the balloons?

Expected responses – Air has or support weight. Bicycles, cars and lorries are resting on tyres containing a lot of air. 

 

 

PROPERTIES OF AIR

2. Air occupies space.

3. Air exert pressure.

4. Air supports weight.

 

 

LESSON 3 – USES OF AIR
