Syntax

Teacher Activity

Pupil Response

Phase 1 — Encounter the Puzzling Situation

Teacher systematically presents the topic Atmosphere in front of the students. We know that Earth is surrounded by air, which makes life possible. In order to collect the attention of students, the teacher presents some video clippings showing Earth from space, aeroplanes flying, clouds, and satellites orbiting Earth. The teacher also shows pictures related to weather changes and space travel.

Then the teacher asks:

·         What surrounds the Earth?

·         How do aeroplanes fly in the sky?

·         Why do meteors burn before reaching Earth?

·         Is the atmosphere the same everywhere?

All these questions are very relevant and we must think about them. We must develop certain concepts about what the atmosphere is and what its layers are.

Then the teacher presents more visuals showing the different layers of the atmosphere to create curiosity.

Students become interested and attentive.

 

 

Phase 2 — Explore Reaction to the Situation

In order to collect students’ attention related to atmosphere, the teacher consciously asks certain questions about it. Then the teacher collects the responses of students and provides support.

Students share their ideas:

·         Air is everywhere.

·         Planes fly in the sky.

·         Clouds bring rain.

Teacher acknowledges responses and guides discussion.

 

 

Phase 3 — Formulated Study Task and Organized Themselves for Study

Dear students, as responsible learners we must understand how the atmosphere protects us and supports life. We must find out what the layers of atmosphere are and what their features are.

Then the teacher divides the class into five groups and assigns:

Group 1 — Troposphere
Group 2 — Stratosphere
Group 3 — Mesosphere
Group 4 — Thermosphere
Group 5 — Exosphere

Students collectively find out the features, importance, and functions of their assigned layer.

 

 

Phase 4 — Independent and Group Study

The teacher organizes a particular place for each group for discussion and enquiry. The teacher provides appropriate study materials and learning aids for each group.

Teacher provides proper guidance and support.

 

Group 1 — Troposphere

Lowest layer of atmosphere where we live.

Features:

  • Weather changes occur here
  • Contains oxygen and water vapor
  • Aeroplanes fly in this layer

Importance:

  • Supports life
  • Controls climate

Group 2 — Stratosphere

Layer above troposphere.

Features:

  • Contains ozone layer
  • Protects Earth from harmful ultraviolet rays
  • Jet aircraft fly here

Importance:

  • Protects living organisms

Group 3 — Mesosphere

Middle layer.

Features:

  • Meteors burn in this layer
  • Very cold temperature

Importance:

  • Protects Earth from meteoroids

Group 4 — Thermosphere

Upper layer with very high temperature.

Features:

  • Contains ionosphere
  • Radio communication occurs
  • Northern lights occur

Importance:

  • Helps communication systems

Group 5 — Exosphere

Outermost layer.

Features:

  • Very thin air
  • Satellites move here

Importance:

  • Helps space communication and research

 

Phase 5 — Analysis Progress and Process

Each group presents their ideas and discussion points collectively. Students, with the support of teacher and learning materials, find out the features and importance of their atmospheric layer.

Group members present their ideas creatively using charts and diagrams.

Teacher appreciates each group and the effort taken by them.

 

 

Phase 6 — Recycle Activity

The teacher presents another topic in front of the students for further studies:

“What will happen if the atmosphere gets polluted?”

Students are placed in another puzzling situation and think about protecting the atmosphere.

 

 

Social System

At first teacher activities present a topic in front of the students. After that classroom becomes student-centered and teacher acts as a facilitator to provide a healthy learning environment with sufficient learning materials.

Principle of Reaction

Teacher motivates students in collaborative and cooperative learning and provides proper guidance at appropriate stages.

Teacher appreciates participation and encourages enquiry.

Support System

Teachers handbook, textbook, charts showing layers of atmosphere, video clippings related to atmosphere, globe, diagrams, worksheets, and reference materials.

Instructional Effect

Students understand about atmosphere and its layers. Through discovery learning students establish concepts clearly. Discussion points are presented in groups creatively and informatively.

Nurturant Effect

Students become responsible and committed in their group work. Enquiry learning takes place. A healthy and friendly relationship is established among students.
