When is Required Class 9 Science
If I understand your question correctly, you may be asking about when CBSE Class 9 Science is typically taught or the academic year during which students study this subject.
In the CBSE (Central Board of Secondary Education) system in India, Class 9 Science is usually taught during the academic year that runs from April to March. The curriculum is divided into two terms: Term 1 and Term 2. The distribution of topics may vary depending on the school and the schedule they follow.
Term 1 typically covers about 50% of the syllabus and is conducted in the first half of the academic year, starting in April and concluding around September or October. Term 2 covers the remaining 50% of the syllabus and is conducted in the second half of the academic year, starting around October and concluding in March.
It’s important to note that the exact schedule may vary from school to school. Some schools might follow a different division of the syllabus into terms or have variations in the academic calendar.
If you are a student or a parent seeking information about the specific schedule for Class 9 Science in a particular school, I recommend checking with the school administration or referring to their academic calendar.

Case Study on Class 9 Science
“Green Energy Initiatives in ABC School”
Background: ABC School, a prominent educational institution, located in a metropolitan city, had been facing rising electricity costs and environmental concerns due to its heavy dependence on conventional energy sources. The school administration decided to take a proactive step towards sustainability and energy efficiency by implementing renewable energy solutions.
Objective: The main objective of the case study was to explore the feasibility and effectiveness of renewable energy sources in reducing electricity consumption, minimizing carbon emissions, and promoting environmental awareness among students and staff.
Methodology:
- Solar Power Installation: The school invested in the installation of solar panels on the rooftops and open areas of the campus. The solar panels were interconnected with the school’s electrical grid to harness sunlight and convert it into electricity.
- Wind Turbine: In addition to solar panels, the school explored the feasibility of installing a small wind turbine on the campus. Wind energy was considered to supplement solar power during periods of low sunlight.
- Energy Monitoring: To assess the impact of renewable energy initiatives, the school implemented an energy monitoring system to track electricity consumption before and after the installation of renewable energy sources.
- Student Engagement: The school organized awareness campaigns and workshops to educate students about renewable energy, climate change, and the importance of sustainability.
Results:
- Reduction in Electricity Bills: The solar panels and wind turbine significantly reduced the school’s dependence on conventional electricity. As a result, the school’s electricity bills dropped considerably over time.
- Environmental Impact: The renewable energy initiatives led to a substantial reduction in the school’s carbon footprint. The school’s contribution to greenhouse gas emissions decreased, contributing positively to the environment.
- Educational Impact: The students’ understanding of renewable energy sources and environmental issues increased, fostering a sense of responsibility towards sustainable living.
