Questions and Solutions
चलो, करके देखें
Q1. कुछ ईंटें लो। इन्हें किसी खुली जगह पर सीधी लाइन में रखो, जैसे चित्र में दिखाया गया है। अब इन पर चलने की कोशिश करो। क्या यह आसान लगा?
Q2. अपनी टीचर की मदद से चार-पाँच बाँसों को बाँध कर एक छोटा सा पुल बनाओ। उस पर चल कर देखो। (क) तुम्हें कैसा लगा? (ख) गिरे तो नहीं?
Q3. जूते या चप्पल पहन कर पुल पर चलना ज्यादा आसान होगा या नंगे पैर? क्यों?
करके देखो
Q1. चित्र 1 और 2 को देखो। बच्चे कुँए से बाल्टी खींच रहे हैं। क्या दोनों चित्रों में अंतर बता सकते हो?
Q2. इन दोनों में से किस तरह से खींचना आसान होगा-पुली (घिरनी) के साथ या बिना पुली के?
Q3. अपने आस-पास देखो। तुम कहाँ-कहाँ पुली का प्रयोग देखते हो? उनकी सूची बनाओ।
- कुएँ से पानी निकालने के लिए।
- निर्माण स्थलों पर भारी सामान उठाने के लिए क्रेन में।
- स्कूलों या इमारतों में झंडा फहराने के लिए।
- पर्दे को खोलने या बंद करने के लिए (कुछ प्रकार के पर्दों में)।
- लिफ्ट (एलिवेटर) में भी पुली सिस्टम का उपयोग होता है।
Q4. तुम भी चरखी या खाली धागे की रील से पुली बनाकर कुछ सामान उठाने की कोशिश करो।
सीमेंट का पुल
Q1. यह पुल बाँस के बने पुल से किस तरह अलग है?
- सामग्री: बाँस का पुल बाँस की लकड़ियों से बनता है, जबकि सीमेंट का पुल सीमेंट, रेत, बजरी और लोहे की छड़ों (सरिया) से बनता है।
- मजबूती और टिकाऊपन: सीमेंट का पुल बाँस के पुल की तुलना में बहुत अधिक मजबूत और टिकाऊ होता है। यह भारी वाहनों का भार भी सह सकता है।
- निर्माण: सीमेंट के पुल का निर्माण अधिक जटिल और समय लेने वाला होता है, जबकि बाँस के पुल अपेक्षाकृत जल्दी और आसानी से बनाए जा सकते हैं।
- उपयोग: सीमेंट के पुल का उपयोग कार, बस, ट्रक जैसे भारी वाहनों के साथ-साथ पैदल चलने वालों के लिए भी किया जाता है, जबकि बाँस के पुल आमतौर पर केवल पैदल चलने वालों या हल्के यातायात के लिए होते हैं।
- स्थिरता: सीमेंट का पुल बहुत स्थिर होता है, जबकि बाँस का पुल थोड़ा हिल सकता है।
Common mistakes
- Not clearly distinguishing between the function of pulleys and other simple machines.
- Underestimating the difficulty of certain modes of transport.
- Failing to provide specific examples of pulley usage in daily life.
Revision tips
- Visualize the different ways students travel to school described in the chapter.
- Draw diagrams of a pulley system and a bamboo bridge to aid understanding.
- Think about other places where pulleys are used besides wells and flagpoles.
- Discuss with friends or family about the advantages and disadvantages of different types of bridges.
Practice MCQs
Q1. Which of these is the easiest way to walk on a bamboo bridge?
Explanation: Walking barefoot provides better grip on uneven surfaces like a bamboo bridge, making it easier and safer to cross.
Q2. What is the primary advantage of using a pulley to draw water from a well?
Explanation: A pulley system helps to change the direction of the force applied, making it easier to lift heavy objects like a bucket of water.
Q3. Which of the following is NOT a typical use of a pulley observed in daily life?
Explanation: While some car windows might have mechanisms, a pulley is not the common or primary method used for opening a standard car window.
Q4. How does walking on a line of bricks compare to walking on the ground?
Explanation: Walking on a line of bricks can be easier than walking on uneven ground as it provides a more defined and potentially stable path, similar to a narrow bridge.
Frequently asked questions
What is the main theme of the NCERT Class 4 आस-पास Chapter 1?
The main theme is exploring the diverse and sometimes challenging ways students travel to reach their schools, introducing concepts like different types of bridges and the utility of pulleys.
How do the NCERT Solutions for 'चलो, चलें स्कूल!' help students?
These solutions provide clear, rewritten answers to all questions, explaining concepts like walking on bricks, crossing bamboo bridges, and the mechanics of pulleys in an easy-to-understand manner for Class 4 students.
What is a pulley and where is it used, according to the chapter?
A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt. The chapter mentions its use in drawing water from a well and at construction sites or for hoisting flags.
Why is walking barefoot suggested for crossing a bamboo bridge?
Walking barefoot provides better grip and sensitivity to the surface of the bamboo, making it easier and safer to maintain balance while crossing a narrow and potentially slippery bridge.
How do the solutions explain the difference between various bridges?
The solutions prompt students to observe and compare bridges like those made of bamboo with cement bridges, highlighting differences in their construction, material, and ease of use.
