Objective of writing exemplar:

The objective of writing this exemplar is to demonstrate how multidisciplinary thinking through an interdisciplinary approach can enhance students' understanding of complex real-world issues, fostering critical thinking and a holistic perspective in their learning

 

Concept: Hydrological cycle, Hydrological cycle in India

 

Description of concepts:

1.    The hydrological cycle, also known as the water cycle, is a continuous process that describes the movement of water on, above, and below the Earth's surface. It involves the evaporation of water from the Earth's surface, the formation of clouds, precipitation in the form of rain or snow, and the eventual return of water to bodies of water such as oceans, rivers, and lakes. This cycle plays a crucial role in maintaining the Earth's water supply and regulating the planet's climate.

 

2.    In the context of India, the hydrological cycle refers to the specific patterns and processes of water movement within the country. India's hydrological cycle is influenced by monsoon seasons, which bring heavy rainfall during the wet season and relatively drier conditions in the dry season. The cycle in India plays a crucial role in agriculture, as much of the country's farmland relies on the monsoon rains for irrigation. Additionally, the cycle impacts water availability, reservoir management, and flood control in different regions of India.

 

 

The hydrological cycle as an example for multidisciplinary thinking, an interface between science and social science learning:

1.    Physics:

The hydrological cycle provides a practical example for physics by illustrating the change of water's state - from ice to water to vapor. Processes like evaporation, evapotranspiration, and condensation involve energy transfer and thermodynamics, making it a solid foundation for understanding the physical aspects of the cycle.

2.    Chemistry:

Chemistry plays a vital role in the hydrological cycle, particularly in terms of water purification. Students can delve into how the cycle acts as a natural purification system, converting saline or polluted water into clear water. This perspective involves chemical reactions and equilibrium, offering insights into water quality and purification.

3.    Botany:

Integrating botany into the discussion allows students to appreciate the role of vegetation in the hydrological cycle. Concepts like evaporation, transpiration and the retarding effect of vegetation on evaporation can be explored. The question of whether forests attract rain and clouds adds an ecological dimension.

4.    Geography:

Geography provides essential insights into the temperature distribution and its impact on the rate of evaporation. Students can investigate how the hydrological cycle serves as a pump, lifting sea-level or groundwater to mountain tops, taking into account topography and climatic regions. Furthermore, the geographical aspect of the cycle includes the forms of condensation and precipitation, which are influenced by local conditions.

5.    Environmental Science:

This interdisciplinary approach allows students to understand the role of the hydrological cycle in creating floods and causing droughts. It emphasizes the complex interactions between climate change and hydrological aspects, shedding light on the environmental consequences of the cycle.

6.    Human Factors:

Here, the interface between science and society emerges. Students can examine how human activities, policies, and resource management impact the hydrological cycle. This perspective encourages critical thinking regarding the societal implications of water-related decisions, such as water resource allocation and urban development.

7.    Human Society:

The hydrological cycle significantly affects human society, influencing agriculture, water availability, and disaster management. An interdisciplinary approach allows students to explore the economic, political, and social aspects of the cycle within the context of human society, human life, and even human history.

 

Sample activities for multidisciplinary thinking, an interface between science and social science learning:

An example of how a series of activities related to a concept can be used to promote multidisciplinary thinking and encourage collaboration between teachers of different subjects, such as Life Science, Environmental Science, Physics, Chemistry, Mathematics, and Social Science.
