Lesson Plan Template
Ø Learning
Outcomes
The students will be able to
•
Identify
the features of layers of the atmosphere
•
Relate the importance of atmosphere to human
kind
•
Discuss
the composition of atmosphere & apply that knowledge in real life
•
Realise the importance of rainfall in their
life
Ø Learning
objectives:
The students will be
able to
•
Describe
the structure of the atmosphere.
•
Decsribe
the composition of air and enlist the various gases in it
•
Compare
between atmospheric temperature & Wind Pressure
•
Explain
the mechanism of rainfall
Ø Content of the chapter
Ø Structure
of the atmosphere( Four Different Layers)
•
Troposphere
– Densest Layer, Weather Changes
•
Stratosphere
–Calm & Clear Air, Aircrafts often fly in this layer
•
Mesosphere
– Ozone is formed, Act as shield
•
Thermosphere
– Thin layer, Ion particles(Wire Communication)
Ø Air
& It’s Composition – Majorly 3 gases in the atmosphere
1. Nitrogen – Occupies 78%, Used by plants to support
their growth & Development
2. Oxygen – Occupies 21% , Life Supporting Gas
3. Carbon Dioxide – Occupies 0.03%, Cause of Global
Warming, Cause in Increasing Temp.
Ø Pollutants
In The Air
1. Mobile - Automobiles release Gases like Carbon
mono-oxide, Sulphuric Dioxide
2. Natural – Volcanic eruptions & Forest fire
3. Stationary – Factories
Ø Atmospheric
Temperature & Pressure
1. Instrument
2.
Unit
of air pressure
3.
Variation
in atmospheric temperature & pressure
4.
Wind
Ø Mechanism
of Rainfall
1.
Water
cycle and importance of rainfall
Ø Monitoring
weather conditions
1.
Difference
between weather and climate Uses of weather report
Ø Teaching
strategy
1.
The
teacher will explain the structure of atmosphere with the help of visuals.
It will also help them to understand the
structure of the atmosphere
2.
It
will be followed by a pie diagram on the topic composition of air. The students
will be asked questions and discussion will be followed on percentage and
importance of gases
3.
Class
room discussion will be held on the topic pollutants of the air. The knowledge
of this will help the students to reduce pollution
4.
Mechanism
of rainfall will be explained with the help of diagram on the blackboard
5.
Students
group reports on monitoring weather conditions- use of any newspaper report
will help students to again a comprehensive study of weather reports
