Write a factual description, in not more than 100 words, of a working model of 'Save Your Earth' that you have prepared for your school's Earth Day Exhibition.
The 'Save Your Earth' working model demonstrates sustainable urban living. Built on a recycled wooden base, it features a miniature city with a functioning solar panel array that powers LED streetlights. A central water pump illustrates a rainwater harvesting system, channeling water to a small green belt. To depict waste management, color-coded segregation bins are placed near the residential units. A motorized wind turbine on the outskirts shows renewable energy generation. The model effectively visualizes eco-friendly solutions to modern environmental challenges, emphasizing conservation through interactive components and renewable energy technology.
Marking Scheme
- 11 mark for Heading/Introduction (model name and what it represents).
- 22 marks for physical description and working components (at least 2-3 functional parts described).
- 31 mark for language coherence, factual tone, and adherence to 100-word limit.
Hint
Describe at least two moving or functional parts of the model and use technical terms for materials and components.
Quick Oral Answer
My working model demonstrates sustainable urban living with a solar-powered LED system, a rainwater harvesting pump, color-coded waste bins, and a motorized wind turbine. Each component is functional, showing renewable energy and conservation solutions on a recycled wooden base.
Analysis & Explanation
This question tests the ability to write a factual description -- a specific CBSE writing format that requires objective, detail-oriented prose without literary embellishment. The marking scheme awards 1 mark for heading/introduction, 2 marks for the physical description and working components, and 1 mark for language and coherence. The key challenge is the word 'working' in the question. Students must describe components that actually function or move, not just static displays. For example, a solar panel that powers LEDs, a pump that circulates water, or a motorized wind turbine are all 'working' elements. Simply describing a poster or a painted diorama would miss this crucial requirement. The 100-word limit demands precision -- avoid filler phrases like 'it is very beautiful' or 'everyone liked it'. Instead, use specific technical terms: 'recycled wooden base', 'rainwater harvesting system', 'color-coded segregation bins'. Each sentence should add new factual information. A structured approach works best: start with the overall model (what it represents), then describe 3-4 specific components and their functions, and conclude with the model's purpose or message. Avoid first-person narrative ('I made this model') as factual descriptions should be impersonal.
Common Mistakes
- 1Using creative or emotional language ('This beautiful model will save our precious planet!') instead of factual, objective descriptions of components and their functions.
- 2Failing to describe the 'working' aspect of the model -- students describe a static display or poster rather than mentioning functional parts like pumps, motors, or electrical circuits.
- 3Exceeding the 100-word limit by adding unnecessary adjectives or repeating the same point, which shows poor conciseness skills and costs marks under expression.
Interesting Facts
Earth Day was first celebrated on April 22, 1970, when 20 million Americans protested environmental degradation, leading to the creation of the US Environmental Protection Agency (EPA) and landmark laws like the Clean Air Act.
India generates over 62 million tonnes of solid waste annually (2023 data), but only about 20% is processed or recycled, making waste management models like the one described particularly relevant for school exhibitions.
The world's first solar-powered school was built in Auroville, India, in 1971, and today India has over 15,000 schools with rooftop solar panels under the PM-KUSUM scheme.
Frequently Asked Questions
What is the difference between a factual description and a creative description?
A factual description is objective and focuses on measurable details -- dimensions, materials, components, and functions. A creative description uses literary devices like metaphors and emotional language. CBSE asks for factual descriptions in this section.
How do I make my factual description of a 'working model' stand out?
Emphasize the 'working' aspect by describing at least two functional or moving parts (e.g., a pump that circulates water, a solar panel that lights LEDs). This shows the model is not just static but interactive.
Should I include a heading or title for the factual description?
Yes, include a brief heading like the model's name ('Save Your Earth -- Working Model'). This earns you part of the format mark and immediately orients the reader.
