बचपन में लेखक अपने मामा के गाँव चाव से इसलिए जाता था क्योंकि लेखक के मामा के गाँव में लाख की चूड़ियाँ बनाने वाला कारीगर बदलू रहता था। लेखक को बदलू काका से अत्यधिक लगाव था। वह लेखक को ढेर सारी लाख की रंग-बिरंगी गोलियाँ देता था इसलिए लेखक अपने मामा के गाँव चाव से जाता था।
गाँव के सभी लोग बदलू को ‘बदलू काका’ कहकर बुलाते थे इस कारण लेखक भी ‘बदलू मामा’ न कहकर ‘बदलू काका’ कहता था।

शिक्षा या ज्ञान प्राप्त करना हर व्यक्ति का मूलभूत अधिकार है और अच्छी शिक्षा देश के प्रत्येक नागरिक को मिलना ही चाहिए। शिक्षा ही व्यक्ति का संपूर्ण विकास कर सकती हैं। उसके बौद्धिक , मानसिक व आर्थिक स्तर को ऊंचा कर सकती हैं। उसके सोचने समझने की शक्ति का विकास कर सकती हैं।
अच्छी शिक्षा हासिल करके ही अच्छे एवं सुरक्षित भविष्य की नींव डाली जा सकती है। इसीलिए एक सुरक्षित भविष्य के लिए प्रत्येक व्यक्ति को अच्छी शिक्षा लेना अनिवार्य है। और ऑनलाइन शिक्षा इसमें महत्वपूर्ण भूमिका निभा रही है। ऑनलाइन शिक्षा से कई फायदे हैं।
ऑनलाइन शिक्षा घर बैठे-बैठे इंटरनेट के माध्यम से मिलने वाली शिक्षा है।इसलिए यह शिक्षा विद्यार्थी न सिर्फ अपने देश से बल्कि विदेशों की शिक्षण संस्थाओं से भी हासिल कर सकते हैं।
ऑनलाइन शिक्षा व्यक्ति घर बैठे-बैठे हासिल कर सकता है। जिससे विद्यार्थियों के शिक्षण संस्थाओं , कोचिंग संस्थाओं या स्कूलों में जाने वाले समय की बचत होती है। साथ ही साथ यात्रा में लगने वाले पैसे की भी बचत हो जाती हैं।
छात्र अपने समय व सुविधा के हिसाब से ऑनलाइन क्लासेस ले सकते हैं।और शिक्षक द्वारा दी जाने वाली ऑनलाइन क्लास की रिकॉर्डिंग भी की जा सकती हैं। ऐसे में अगर किसी विद्यार्थी को ऑनलाइन क्लास के वक्त किसी विषय से संबंधित कुछ टॉपिक समझ में ना आए। तो वह दुबारा रिकॉर्डिंग सुन कर अपनी शंकाओं को दूर कर सकता है।
यदि किसी विद्यार्थी को किसी विषय से संबंधित कोई कठिनाई हो रही हो या कोई प्रश्न समझ में नहीं आ रहा हो। ऐसे में बच्चे अपने शिक्षकों से अपने घर बैठे बैठे ऑनलाइन क्लासेस के माध्यम से दोबारा प्रश्न पूछ सकता है।
न सिर्फ स्कूल , कॉलेज जाने वाले बच्चे बल्कि ऐसे विद्यार्थी जो प्रतियोगिता परीक्षाओं की तैयारियां कर रहे हैं। उनको भी ऑनलाइन कोचिंग की सुविधा प्राप्त हो रही है। अब वो भी घर बैठे बैठे अपनी आने वाले प्रतियोगिता परीक्षाओं की तैयारी आराम से कर सकते हैं।
ऑनलाइन शिक्षा से घर बैठे बैठे पढ़ने की सुविधा तो मिलती ही है। साथ में समय पैसे दोनों की बचत होती है।
ऑनलाइन पढ़ाई में अनेक ऐसे ऐप हैं जैसे गूगल अर्थ , वीडियो , चित्र , एनिमेटेड चित्र , गूगल मैप्स। जिनका प्रयोग कर पढ़ाई को और भी दिलचस्प बनाया जा सकता है। इसमें शिक्षक व विद्यार्थी एक दूसरे को पीडीएफ फाइल , वेब लिंग , वीडियो बनाकर भी भेज सकते हैं।
कई कंपनीयों द्वारा लर्निंग एप्स (Learning Apps ) भी बनाए गए हैं। जैसे मेरीटनेशन , बाईजू टॉपर्स आदि। ये लगभग कक्षा 1 से लेकर कक्षा 12 तक के सीबीएसई के पाठ्यक्रम को ऑनलाइन प्रदान करते हैं। और इनके द्वारा बनाए गए एप्स में शिक्षकों का पढ़ाने का तरीका इतना बेहतरीन है कि बच्चे आराम से उस विषय को समझ जाते हैं।
इनकी सबसे बड़ी खासियत यह है कि ये अपने ऐप से जुड़ने वाले बच्चों से पर्सनली सम्पर्क में रहते हैं। और कोई समस्या होने पर इनके टीचर बच्चों की समस्याओं का समाधान तुरंत करते हैं।
यहां तक कि कुकिंग , सिलाई , कढ़ाई , क्राफ्ट , ड्राइंग , पेंटिंग आदि से संबंधित क्लासेज भी अब ऑनलाइन दी जा रही है।

Birsa Munda was a young freedom fighter and a tribal leader, whose spirit of activism in the late nineteenth century, is remembered to be a strong mark of protest against British rule in India. Born and raised in the tribal belt around Bihar and Jharkhand, Birsa Munda’s achievements are known to be even more remarkable by virtue of the fact that he came to acquire them before he was 25. In recognition of his impact on the nationals movement, the state of Jharkhand was created on his birth anniversary in 2000.
Born on November 15, 1875, Birsa spent much of his childhood moving from one village to another with his parents. He belonged to the Munda tribe in the Chhotanagpur Plateau area. He received his early education at Salga under the guidance of his teacher Jaipal Nag. On the recommendation of Jaipal Nag, Birsa converted to Christianity in order to join the German Mission school. He, however, opted out of the school after a few years

Parts
Cell Membrane
- The outer boundary of cell enclosing nucleus and cytoplasm is called cell membrane or plasma membrane.
- The cell membrane separates cell and its components from the outside environment. Also, it separates cells from one another.
- The cell membrane is porous to specific ions and organic molecules and controls the movement of substances in and out of the cells. Therefore, the cell membrane is selectively permeable.
- It gives shape to the cell.
- In plant cells, there is an additional thick layer surrounding cell membrane called cell wall. The cell wall gives rigidity to the cell. It protects the plant cells against different environmental conditions like high wind speed, atmospheric pressure, etc. We can observe cells in the leaf peel of Tradescantia, Elodea, Rhoeo or onion peel.
Cytoplasm
- It is a jelly like fluid present between nucleus and cell membrane.
- Organelles like chloroplast, mitochondria, golgi apparatus, ribosomes, etc. are dispersed in cytoplasm.
Nucleus
- Generally, it is spherical in shape and located in the center of the cell.
- A membrane called nuclear membrane separates nucleus from the cytoplasm.
- The nucleus is the control center as it regulates all the activities of the cell.
- When nucleus is observed under microscope, a small spherical body in the nucleus was seen and called nucleolus. Also, it contains thread-like structures called chromosome. These chromosomes carry genetic material (genes) and help in inheritance/transfer of characters from parents to offspring.
- The nuclear membrane is porous and allows the movement of materials between cytoplasm and nucleoplasm (Nucleolus and Chromosomes).

- Cell: The fundamental unit of structure and function in living organism.
Example: Blood cells, Nerve cells, etc.
Cell is made up of basically 3 components: Cell Membrane, cytoplasm and nucleus.

Federalism: This refers to the existence of more than one level of government in the country. In India, we have governments at the state level and at the centre. Panchayati Raj is the third tier of government. While each state in India enjoys autonomy in exercising powers on certain issues, subjects of national concern require that all of these states follow the laws of the central government. Under federalism, the states are not merely agents of the federal government but draw their authority from the Constitution as well. All persons in India are governed by laws and policies made by each of these levels of government.
