| 7.Declaration of
the topic |
Let us understand the forces that affect a flying kite. |
| 8.Lesson Summary |
Introduction
|
| |
- Types of forces -gravity, lift, thrust and drag.
- A kite is a special sort of aircraft, attached to the ground by a string.
- The pressure of air.
- The stability of the kite.
|
9. Student's objectives and
learning outcomes: |
Knowledge
- Pupils recall the concept about gravity.
- Pupils list out different types of forces.
- Pupils define different terms used like Gravitational force, thrust, pressure, lift etc.
- Pupils identify the shape of a kite and its Significance in terms of air pressure.
|
|
Comprehension
- Pupils differentiate between the kites, Aeroplanes and gliders.
- Pupils compare the nature of the forces Like gravity, lift, thrust and drag.
- Pupils select the proper material for Making a kite, a proper tail attached to the Kite.
- Pupils interpret and summarizes the Observations made during the kite making And kite flying.
- Pupils locate the height at which the Greatest amount of lift is produced.
|
|
Application
- Pupils apply the concept of air pressure, in lifting a kite.
|
|
Skill
- Pupils locate the points on the kite to tie the Knots.
- Pupils draw the diagrams of the kites.
|
|
Analysis
- Pupils experiment with different sizes and Shapes of the kites and their tails.
|
|
Synthesis
- Pupils set up the materials required to Make and fly a kite.
- Pupils collect information about various Designs of the kites used in several
Parts of the world.
- Pupils prepare the results of the experiments Done with different types of kites and flown At different places and at different times in the Form of a tabular column.
- Pupils develop a habit of and skill of drawing neat-labeled diagrams.
|
|
Evaluation
- Pupils justify and compare the answers.
- Pupils estimate the approximate height at which The kite will have maximum lift.
