सार

जल और वायु महत्वपूर्ण संसाधन हैं; EVS उनके स्रोत, उपयोग, संरक्षण और प्रदूषण से रक्षा सिखाता है।

मुख्य बिंदु

  • वर्षा मीठे पानी का मुख्य स्रोत है; नदियाँ, झीलें, कुएँ और भूजल इसे संग्रहीत करते हैं।
  • जल चक्र: वाष्पीकरण, संघनन, वर्षण।
  • वर्षा जल संचयन और पुनः उपयोग पानी बचाते हैं।
  • प्रदूषित जल हैज़ा और टाइफ़ाइड जैसे रोग फैलाता है।
  • वायु प्रदूषण वाहनों, कारख़ानों, जलाने और धूल से आता है।
  • स्वच्छ जल और वायु स्वास्थ्य के लिए आवश्यक हैं।

व्याख्या

  • पारंपरिक व्यवस्थाएँ (बावड़ियाँ, जोहड़) स्थानीय ज्ञान दिखाती हैं।
  • सरल फ़िल्टर दिखाते हैं कि पानी कैसे साफ़ होता है।
  • पेड़ वायु प्रदूषण घटाते हैं।
  • बच्चे विद्यालय में पानी के उपयोग की जाँच कर सकते हैं।
  • पानी उबालने से कीटाणु मरते हैं।

चरण-दर-चरण

  1. पूछी गई अवधारणा, कानून या तथ्य पहचानें।
  2. परिभाषा, सूत्र, उदाहरण या वर्ष याद करें।
  3. उसे लागू करें और बेमेल विकल्प हटाएँ।

उदाहरण

  • बच्चे हिसाब रखते हैं कि उनका परिवार एक दिन में कितना पानी प्रयोग करता है → संरक्षण जागरूकता।
  • छत से वर्षा जल टंकी में इकट्ठा करना → संचयन।
  • पत्तियाँ जलाने से धुआँ → वायु प्रदूषण।

ग़लतियों से बचें और उन्नत बिंदु

  • सामान्य भूल: यह कहना कि भूजल असीमित है।
  • सामान्य भूल: स्वास्थ्य से संबंध की अनदेखी।
  • सामान्य भूल: बिना कार्य के केवल तथ्य।

त्वरित पुनरावृत्ति

  • जल चक्र।
  • वर्षा जल संचयन।
  • प्रदूषण के स्रोत और स्वास्थ्य।
