What simple steps can students take on their balconies or school grounds to help birds during scorching summer seasons?
[3 Marks]
✅ Step-by-Step Solution & Working
Students can provide life-saving relief to urban birds during summer by:
1. Installing an Earthen Water Bowl (Sakora): Placing shallow terracotta bowls of clean water in shaded corners and refilling them twice daily.
2. Hanging Grain Feeders: Placing small wooden or recycled bottle feeders with millet (bajra), broken wheat (dalia), or sunflower seeds.

Q2 Humane Treatment of Street Animals
Why should people never throw stones or firecrackers at stray dogs and cats?
[3 Marks]
✅ Step-by-Step Solution & Working
Street animals feel physical pain, terror, and grief just like humans. Throwing stones or firecrackers at them causes severe fractures, burns, and psychological trauma. Traumatized dogs may become fearful and defensively bite innocent passersby. Compassionate feeding, vaccination, and sterilization keep neighborhood animals calm, healthy, and friendly.

🌟 NEP 2020 Competency-Based Case Study

Urban Wildlife Conflict: The Glass Window Hazard

A newly built glass office building in town reports that dozens of sunbirds and kingfishers crash into the clear glass facade every week because the glass reflects surrounding trees and blue sky like an open path.

Analytical Task: How can the building management and local children solve this hazard to live in harmony with urban birds?
Evaluation & Model Answer:
The bird collision problem occurs because birds perceive the glass reflection as continuous sky or foliage. To eliminate this hazard: (1) Apply frosted, patterned, or silhouette stickers (such as falcon decals or dense dot arrays spaced 5 cm apart) on external window panes so birds recognize a barrier. (2) Install outdoor blinds or lightweight nylon netting. (3) Turn off unnecessary bright internal lights at night to prevent disorienting migratory birds.
Rubric: Understanding reflection hazards, practical non-invasive deterrents (window decals, netting), compassionate architectural ethics (4 Marks).
