National Curriculum Framework (NCF) for School Education-2023


 

The latest National Curriculum Framework (NCF) for School Education 2023 outlines a comprehensive action plan for teaching science in classes 9 to 12. Here are the key elements of this action plan:

1.Capacities for Scientific Inquiry:

         ·       Focus on developing students' abilities to conduct scientific inquiry, including hypothesis formulation, experimentation, observation, and interpretation of data.

         ·   Encourage understanding of fundamental scientific theories, laws, and concepts across disciplines such as Biology, Chemistry, Physics, and Earth Science.

2. Interdisciplinary Approach:

      Promote an interdisciplinary understanding of science, connecting it with other subjects like mathematics, environmental education, and technology.

      Implement thematic studies that integrate various scientific disciplines to address real-world problems and contemporary challenges.

3.Practical and Experiential Learning:

  · Emphasize hands-on experiments, field trips, and project-based learning to enhance practical understanding.

  · Incorporate laboratories, science clubs, and fairs to provide experiential learning opportunities.

4.Use of Technology and Digital Tools:

  · Integrate digital tools and resources to facilitate interactive and engaging learning experiences.

  · Encourage the use of simulations, virtual labs, and online resources to complement traditional teaching methods.

5.Environmental Education:

  · Highlight the importance of environmental sustainability and integrate environmental education across the science curriculum.

  · Include topics related to climate change, biodiversity, pollution, and conservation in the curriculum.

6.Vocational Education:

  · Incorporate elements of vocational education related to science, such as agricultural science, biotechnology, and health sciences.

  · Provide students with opportunities to engage in vocational training and real-world applications of scientific knowledge.

7.Flexible and Choice-based Curriculum:

  · Offer flexibility in subject choices, allowing students to select combinations of science with other subjects according to their interests and career aspirations.

  · Ensure there is no strict separation between academic and vocational streams, providing an integrated learning experience.

8.Assessment and Evaluation:

  · Implement continuous and comprehensive evaluation methods, including formative and summative assessments.

  · Focus on assessing both theoretical understanding and practical skills through various evaluation tools like projects, lab work, and written exams

distinguishing features between overloading and short circuiting in domestic circuits

 Q. List two distinguishing features between overloading and short circuiting in domestic circuits. (CBSE 2014)

ANS-If too many electrical appliances of high power rating are switched on at the same time, they draw an extremely large current from the circuit causing overloading. 

Due to an extremely large current flowing through the circuit, the copper wire of the household wiring gets heated to a very high temperature and a fire may start. 

Short-circuiting: The touching of naked live wire and neutral wire directly causes short circuiting. In this case, the resistance of the circuit so formed is very small, thus a large amount of current flows through the circuit and heats the wires to a high temperature and a fire may start


Overloading of an electrical circuit

Q. What is meant by overloading of an electrical circuit? Explain two possible causes due to which overloading may occur in household circuit? Explain one precaution that should be taken to avoid the overloading of domestic electric circuit.

ANS- Overloading: The current flowing in domestic wiring at a particular time depends on the power ratings of the appliances being used. If too many electrical appliances of high power rating are switched on at the same time, they draw extremely large quantity of current from the circuit. This is known as the overloading of the circuit. 

Due to large current flowing through the wires of the household circuits, their copper wires get heated up to a very high temperature and can cause a fire.
